How to Create a Bootable Windows SD Card or Flash Drive
Here’s how to create a bootable Windows SD card or USB flash drive. This is perfect for installing windows on a Netbook or Tablet PC.
If you’re working with a netbook or a tablet computer, you likely won’t have an included DVD-ROM drive. Normally this is fantastic! It makes your overall device lighter, and less expensive. But, if you need to install or reformat Windows, then you run into some problems rather quickly. No DVD-drive means you can’t just burn a copy of Windows and throw it in there. Fortunately, most netbooks have an SD Card slot, and ALL of them support USB Pen Drives. Let’s use that to our advantage and get Windows running!
What you need to do this:
- A minimum of an 8GB* removable storage disk. This storage can be an SD card or a USB Flash Drive.
- A computer that is already running Windows.
- A Windows 7, Vista, or XP installation disk, or .iso file equivalent.
Although you only need 8GB, just grab a 32GB or 64GB from Amazon. As of 2017, it’s probably more expensive to buy a smaller drive vs. a 64GB or larger. Also, don’t forget to verify the motherboard you’re installing Windows on supports booting from a USB / removable storage drive. This is fairly common now but if you’re trying to install Windows on an older machine, something to think about if you run into issues.
Got all that? Way to go! Let’s get started.
Step 1
Alright, so you have your SD Card or a USB Pen Drive (some people call either of these flash drives.) Keep in mind that if you go the SD Card route, make sure your computer has an SD Card reader. Good news, they are cheap on Amazon so not a big deal if you need to order one real quickly.
Once you have procured yourself one of these, plug it into your computer. If you have anything valuable saved on your portable storage, backup any data you have saved on your SD/USB before we get started. In the steps that follow we’ll be formatting and completely cleaning it out in the process of turning it into a windows boot disk.
*Oh, before I forget, a great thing about USB Flash Drives, I suppose a 3GB drive would work, but as far as I know, that is a very unusual size. And besides, once you are done installing you can use the 4GB drive for ReadyBoost to improve your system performance.
Step 2
Go to the Start menu and Type cmd in the search box to open up the command prompt.
In this tutorial we’ll run into a lot of command-line, so to keep it easy I’ll just list the command for each step. You’ll need to Press Enter after each command is typed out.
First, we need to open diskpart, which is a cmd-line program built-in to Windows.
Type: Diskpart
Step 3
A new window should appear with the system32\diskpart.exe in the title bar.
Type: list disk
Some disks should appear in a small matrix (chart.) Look for the one that matches the size of your SD Card/USB drive. It might not be an exact match since actual usable disk space is about 5% less than what is advertised. For the next command, you need to enter the number that corresponds to that drive.
Type: select disk 2
Step 4
Now that the disk is selected, we can start cleaning it up and getting it ready. These commands should be the same for everyone, so just enter them one after the other.
Type: clean Type: create partition primary Type: select partition 1 Type: active Type: format fs=fat32
Step 5
Formatting will take a couple of minutes, so now is a good time to grab a snack. ;)
Once it is done, we’ll assign a drive letter to your newly formatted removable storage disk.*
Type: assign letter=y Type: exit
*You don’t have to use the letter “y” but since that is likely not taken we’ll use it for this tutorial to keep things simple.
Step 6
If you have a Windows 7 installation DVD, insert it into your DVD drive. If instead, you have an installation .ISO, then mount it on your computer using a Virtual disk drive.
Once your disk is inserted, Click the Start Menu and then Click Computer. A window should pop-up listing all of your hard drives and removable storage. Look for your DVD drive and take a note of what letter is assigned to it. If you are using a virtual drive, it might be called the BD-ROM drive instead of DVD. In my case, the DVD drive is assigned the letter “e,” so that is what I’ll be using in the next step.
Step 7
Now, all we have to do is copy the files from the installation disk to the sd card. In the example below, e:\ is my DVD drive and y:\ is my SD card.
Type: xcopy e:\* y:\ /s /e /f
This process might take a while since you are transferring a little over 2GB worth of files.
Done!
After the files ultimately transfer, you are done! You now have yourself a Windows installation portable drive.
Now for the computer that you want to install Windows on using this, all you need to do is restart the computer and spam-press the F2 key while it is booting up; or whatever the setup key is, but F2 is the standard for many systems. Pushing the F2 key should load up the system Bios. Here you have to go into the Boot Device Priority section and change the USB/SD card to #1 on the priority list. Once this is set, your computer should treat your SD/USB just like a Windows 7 Installation DVD.

Thank you, it worked perfect for my SD Card.
Leebo
Awesome thanks!
bice
cool! works perfect! i <3 you! :D

Ewww!!! :$

Awesome site…Useful Information ….
gegil1
It gives me access denied on the last step when i try to copy the files to the sd card
Aaron
I know this is very delayed but in case anyone else has the problem you need a space between the “*” and the “y”.
Zack
works well wit de space betwn * and y
anonymous
I know is a little late, but if anyone else has the same problem, you have to open the cmd as administrator. Just right click on the cmd icon and select open as administrator.
Ally
the command took me ages of trial error to get in it is :
xcopy_(your dvd drive letter):*_(sdcard letter):_/s_/e_/f
_ is a space.
suraj rawat
yes! it works sucessfully…! thanks!!!
bb
In my case Avira (antivirus) has been preventing command from succeeding.
Dragos
Type exit diskpart before make last step
stop it
run as an administrator or find a lock or write protection button on your sd card adapter.
Carl
Ok I get to “active” and hit enter and it says no partition selected. tried it 3 times not working for me
Texus Noe
type in select partition 1
If there isn’t a partition, then type “create partition primary” then verify the partition creation by typing “list partition”.
Hope this helps.
Carl
Alrighty then I switched computers and it is working now, then again I could spelled partion like this instead of the partition as I should have.
Oh well it is working
ozgur
cooooooooooool!!!!!!!!!!
Manni
its not a system disk so it will not boot. need system files to boot, xcopy will not do that
smeg off
A system disk is identified by what’s on it. If it has a bootmgr (Windows Boot Manager) it’ll boot.
Cheet
Ok so my problem is after list disk cmd my sd card isn’t shown only my hard drive which windows recognises it and I can use it so why isn’t it showing up?

Hai! i want the page detail with screen short of How to Create a Windows Bootable Install SD Card or USB Flash Drive
Dre
How do you know when the files are done copying?
jerseygadfly
the lowest prompt line shows the file being copied, when the prompt moves down to allow a new command you are done
Nelson Bailey
When files are done copying the C:\ DOS promt will appear on the lower left hand side of screen. basically this is using the old DOS operation system to issue commands.
John
It will return to saying C Drive
John
Alright. I copied the file from MY I=dvd to H=SD card.
I put the sd card into my laptop.
I get the windows install screen.
Butit doesnt find anything for driver to install ??
Finn Skovgaard
Awesome. Exactly what I was looking for while trying to save my Windows 7 with a DVD image after it screwed itself up and none of the diagnostic tools could fix it (no improvement since XP in terms of stability or repairability, if possible even worse).
However, diskpart doesn’t work as you describe on XP. It cannot select a USB key, only a real disk. It doesn’t list a USB key with list disk, only with list volume. One can select volume, but then it refuses to accept clean, since no disk is selected, only a volume. I’ll have to do it on Windows 7.
Finn Skovgaard
http://www.makeuseof.com/tag/how-to-create-a-bootable-usb-drive-from-your-windows-cd/ tells how to create a bootable Windows copy with WinToFlash. Its wizard makes it very simple. One still needs a virtual drive if the image is not on a DVD already.

i want to know how to that before window instalation i how will do bootable any sd card.
so pls help me .

Do not work. LIST DISK do not show SD-Card as ‘Disk’ (only as ‘Volume’) and can not be selected. Further action are not possible.
ill
Dude you are a dipshit leave this site you have no clue what you are talking about
Ian
tells a person to leave a tutorial site because he asked a question
lol
Paul
wtf? why don’t you go to computer -> right-click on your flash drive -> format, select FAT32 and THAT’S IT?!!!
why do you use the command line??? those commands suck! it would be much faster to format it in regular way!
jsvanc
The reason to use the diskpart command is so that you can mark the partition as active. If you don’t do this step, the netbook will not be able to boot from the SD Card.
vishwa
it is very use full
ankit
during the format process….. accidentally the sd card was removed in the middle of the process …and now the sd card cant be mounted by the mobile what to do???????
lex luther
Kick urself in the nuts for starters. try mounting to another pc.
Ron
Put the card in a PC or read it with a card reader. Open ‘My Computer’. Right click the SD card and hit ‘Format…’ Choosing a quick format is fine. Make sure ‘File System’ is set to FAT32. Hit ‘Start’ and when it’s done your SD card will be formatted, which also kind of means it got ‘reset’.
After that, just run through the steps in this article again :)
ASA
Thanks from Lithuania.
Paul
Great Tutorial Worked Perfectly!!!!!!
weiderhosen
you are awesome thnx
Mario Podrecca
thanks dude. very easy steps, good explanation
ebin
but i have no cd i have only a windows .iso file only
Steve Krause
What is it exactly you are trying to do?
Benny
Mount the iso file with Virtual Clone drive.
Marcus2012
Or use 7-Zip (free) and extract all the files from the ISO file.
Sid
Cool man its working !!!!!!!!!!!! :)
Mike
I’m getting stuck on Step 7. After a little while of lines of text appearing in the CMD, a message appears saying “The target volume does not support symbolic links”. Anyone know how to fix this?
veve
same here. you basically need to get out of diskpart by typing exit.
then once you re back to the normal cmd line, type in the line given in step 7 again
Louis Kaplan
Using a 8 GB Sdhc card. Receive a “invalid partition table” message when booting my PC using this card. Any ideas? Maybe I need a smaller (4 gb) card, non-SDHC? I don’t think I made any mistakes with the script above, tried multiple times and receive same message. Thanks for any additional guidance!
Volkan Cengen
Hi. I’ve done all steps without any problem. Now I need to delete these Windows files on my SD card ’cause I want to use the card on my camera. But it doesn’t work! When I try to format the card a message pops up: “Disk is write protected”
How can I solve this issue? Any thoughts?
Marcus2012
Make sure that the slider on the left hand side is pushed up towards the gold pins on the back.
Volkan Cengen
Thanks for the tip but it’s not like that. :) I used that SD card for the first time, I never touched any slider before and after the above mentioned steps. I finished my work (btw I had to boot from a USB hard drive because there was no boot option from SD card :D) and wanted to delete the content.
Bob
Try using the diskpart clean described above

well done. Good job.
I have never seen such an instructive and helpful post.
THANK YOU :)

Many thanks for this helpful and informative set of instructions.

thz, its helpful
MikePa
my question lags rest of the folks comments, hope someone will still answer me. The SD is ready as I follow your easy instructions. unfortunately I’m stuck not having neither the Windows 7 installation DVD not installation .ISO. when I bought the HP desktop W7 came preinstalled and no supporting hardware was included. Is factory image partition that I can use to complete the task? would someone please advice what should I do next?
Steve Krause
Hi Mike,
If you don’t have a DVD with Windows on it or an ISO, you are stuck unfortunately.
Your HP should have a factory partition like you mentioned however that is there only to rebuild your HP box back to the factory image when you received it the first time. It will take your box back to the Windows 7 fresh install. I think there is an “easy” way to use that to build a Windows 7 Install DVD or ISO.
What you might be able to do is wait for Windows 8 to release to consumers in October then goto Windows.com and buy the media for $40 to get Windows 8 DVD media. From there you will be able to build a Bootable USB drive as this article describes.
papajuju
Each time i use DISKPART and SELECT my SD CARD, the card is not readable again ! Even not by Windows !… `-(
Steve Krause
Try using this how-to article. It’s an automated way to do the same thing. https://www.groovypost.com/howto/create-bootable-windows-8-flash-drive/
Spider
Is there a way to do the same thing but rather than use an installation disc or .iso, use a vhd disk with my fully installed windows xp and use that as a kind of live windows environment?
moe
No, sorry… It isn’t possible to do that, you have to backup, clean install Windows, and then restore your data. (This is a reply for anyone else wondering the same thing).
Or you can use cloud storage or something (like OneDrive or Google Drive)
Yarys
great guide..after long time i was doing something like this and copletely forgot how to do it… nice reminder ,how quick its possible forget basics …thanks for saving me :-)

Hello,
I do not have USB/SD card option in my insyde h2o bios !
I can boot from USB but not from SDCARD, how to do ?
Thank you for your help !
Fred
Thank you, it works great !
I had to disable Antivir to be able to copy the file autorun.inf from the W7 iso,
else xcopy is blocked.
Hi Anuj Here.
Thanks u so much.really its working for me.Thanks again………………….

EXCELLENT!!!! THANK YOU VERY MUCH!!!!
Raz
Hey man, I’ve been using the commands I learned here a few times already until I decided to get a USB Stick without formatting it after installation. I am doing another one with Windows 8 now. I have a question still… is there any chance to make Windows 7 and Windows 8 bootable on the same USB Stick and afterwards, when you try to install on a computer just to choose whether you install Win7 or Win8 ? Thanks
kasperr
Hi sir,is it possible to multiboot asd card similar to multiboot usb?If yes please detail the process with each step.
sorin
it is possible to boot an tablet pc,android 4.0,1,5 gb dual core processor,1 gb ram,with this method,the tablet running android,you have an solution about that??
scott
Great! Thanks for this – I’d seen several posts about using diskpart to create the SD volume but they all seemed to miss the bit about setting the active partition – your steps worked perfectly!
Cheers
dwindel
Did fine until the xcopy command. I have the drive letters right, but Windows didn’t recognize the command. Do spaces matter? I tried several combinations.
NitchiFenk
Worked well til the part when I got in to the Setup>Boot>Boot Priority Order .
There was no ” USB/SD “. Can somebody help me ? And is there also a way to undo all of this where in you can use your SD CARD to a storage media again ?
Michael
Hi,
First of, great guide, im getting an error like this:
G:\sources\boot.wim -> Y:\sources\boot.wim
G:\zRCDIMAGE\core.wim -> Y:\zRCDIMAGE\core.wim
File creation error – The parameter is incorrect.
ive used the following parameters:
:\>xcopy g:\* y:\ /s /f
Michael
there is an /e after the /s parameter, dnt know why it didnt got copied.
Michael
Oh damn, nvm i figured it out..
Is there anyway to make this work with NTFS file system? or wont that be bootable?
Anybody?
James
Ok, I know it is 2 years later. I have an acer aspire one D250-1042. I am attempting to put XP on the new hard drive. The last one stopped working. I followed the instructions to the letter, and everything worked. Even got XP on the SD card. My problem is the netbook won’t boot from the sd card. it doesn’t even recognize it in the bios as being there. Help.
CS
I got as far as the “list disk” command. Sadly, when using that command, my SD card is not read by the Command Prompt and only my hard drive is shown. Could someone help me with this?
ayie
how to change the sd card back to normal?
Justine
Great tutorial! To enter setup on my laptop I had to push f10… it previously had Vista installed, I’m in the process of doing a clean install of Windows 7. In case anybody couldn’t get into setup pressing f2, try f10 if you were using Vista.
Roytech
@Justine is correct, just to add, you may also try F11 for the boot options when booting up your Laptop or desktops, it will provide you the list of all the devices on your computer.

Hi there is it normal that when i used the xcopy command and it didint go all the way to end that says successfully copied the installer it only stops at the intsall.wim
THT
late reply, but for others that may be reading this – it doesn’t stop there; it’s just a big file so stays on it for quite a while… just leave it to do it’s thing and once it’s finished you can type in a new command – that’s when you know it really is done :)
Jeffrey Duke
Worked Great. It’s not too bad I’m using a Highspeed 16gb SD Card and so far doing what it’s supposed to great job thanks. :)

Last command don’t work for me. Could you please tell what letter is what? Thank you.

Formatted and copied successfully and boot priority set on SD Card, however when attempting to boot i get:
“File: \Boot\BCD
Status: 0xc000000c
Info: An error occurred while attempting to read the boot configuration data.”
Any ideas? Thanks in advance.

I tried a boot disk and I can’t find the original OEM win 7 disk … grand dad isn’t helping … can’t remember anything …
What can I do ….????

NEED HELP!!!
I have a UMPC and it has only one boot option. boot from “SD SLOT1: Flash memory device”. I need to make a bootable sd card that works for builtin sd card slots. All these methods and other softwares work for USB or USB Card Readers.
KSMaseed
Dear Austin Ruthruf,
It is very good post but I need your help. when I type “list disk” this just show my hard drive but a memory stick. this shows only when it is typed “list volume” but after that next steps can’t be followed because again we have to type “disk number #” while the stick shown is in volume not in disk. Now how to make this as bootable. I am new to this but can do fine; appreciate all yor posts.
thanks and regards.

Hi, I still didn’t find the solution. sd card is not showing in list disk.

My installation DVD consists of 3 nos.(1 of 3, 2 of 3 & 3 of 3), I need to XCOPY one after one? or can I copy all these using normal way: click the DVD drive, copy all files & paste to SD drive?
Thanks,
Owen
The title of your article is misleading. You are giving instructions for making a Windows installation SD or USB, NOT a Windows SD or USB. Big difference. The instructions in this article are all over the internet, the other is harder to find.
Manuel Franco
Exactly! The problem is that it’s not specific enough, and obv it can be Interpreted both ways. Although technically both are boots from removable media; only with different final intent. &BTW, I came searching for the latter reason too ;)
Vojta
I know it’s late, but I have a problem. A quite SERIOUS problem. My computer doesn’t have an OS, and my disc installation media is broken, so I’ve chosen this way. When I try to boot up the PC to the setup, it reads: “An operating system wasn’t found. Try disconnecting any drives that don’t contain an operating system. Press any key to restart.” I’ve done everything right – making the drive itself, giving the flash drive number 1 on the boot order, etc… The drive is not corrupted, I’ve tested it… Please someone help me…

YEAH! It actually works now i have Bootable Windows 7 on 4GB micro sd :D Thanks Mate it just took me 1 and a half Hour .So easy!

What should I do in .iso file case do I have to extract it directly by some iso burner?
Shaun
Download power iso and click mount, then click set number of drives to 1, then go to the iso file, right click and mount it to the drive you just mounted. Then you’re set to copy.

Have enjoyed the comments nearly as much as the tutorial!
The only comment is Have- besides TNX 4 the post- it was well planned-out is that [ coming from a DOS – Disk Operating System] and Pre-DOS background ],
that it ought to be noted that the XCOPY command, rather than using the “_” character to designate a SPACE ( CHR$(32) is usually written with a “^” carrot. C:\>XCOPY^F:\*^Y:\^/s^/e^/f
REM F: is the SOURCE and Y: is the TARGET
and /s /f /e portion are the flags so don’t get the SLASHES mixed.

Most comments are from ppl who missed a step or made a mistake during a step, if anyone is having a problem – Start Over and follow the steps carefully!

Lastly – If you’re in FLORIDA – GET OUT NOW !!

My notebook doesn’t come with the CD. What do I do to xcopy the files to the SD card drive?
Thanks for your kind attention and assistance.

I have successfully completed your steps and have the bootable sd formatted and mounted correctly (I think). My problem now is, the Nextbook I am trying to implement this on has a detachable keyboard that no longer works. So, I cannot use the f2 key to start Windows 10 from the sd. I have been researching this issue and have come across some mentions of sd card drivers that are necessary. Can anyone tell me if this is accurate and, if so, how to get them? Or any other workaround to start the device using the OS on the sd card?

Step 4, Active: The selected disk is not a fixed MBR disk.
The ACTIVE command can only be used on fixed MBR disks.
I have a MicroSD 64GB
