How to make Windows 7 USB flash install media from Linux?

StackOverflow

• Install ms-sys - if it is not in your repositories, get it here. Or alternatively, make sure lilo is installed (but do not run the liloconfig step on your local box if e.g. Grub is installed there!)
• Check what device your USB media is assigned - here we will assume it is /dev/sdb. Delete all partitions, create a new one taking up all the space, set type to NTFS (7), and remember to set it bootable:

# cfdisk /dev/sdb
or fdisk /dev/sdb (partition type 7, and bootable flag)

• Create an NTFS filesystem (if this step produces error, you may need to reboot):

# mkfs.ntfs -f /dev/sdb1

• Write Windows 7 MBR on the USB stick (also works for windows 8), multiple options here:

# ms-sys -7 /dev/sdb
or (e.g. on newer Ubuntu installs) sudo lilo -M  /dev/sdb mbr (info)
or (if syslinux is installed) sudo dd if=/usr/lib/syslinux/bios/mbr.bin of=/dev/sdb

• Mount ISO and USB media:

# mount -o loop win7.iso /mnt/iso
# mount /dev/sdb1 /mnt/usb

• Copy over all files:

# cp -r /mnt/iso/* /mnt/usb/
or use the standard GUI file-browser of your system

• Call sync to make sure all files are written.

...and you're done.

• After all that, you probably want to back up your USB media for further installations and get rid of the ISO file... Just use dd:

# dd if=/dev/sdb of=/win7.img

and reverse if/of next time you want to put the Windows 7 installer onto USB.

As always, double check the device names very carefully when working with dd.

Thank you for this guide!

Windows 10?

Gracias, me funciono perfecto. Thank you.

Windows 10?

same process

mount -o loop win7.iso /mnt/iso returns mount: /mnt/iso: mount point does not exist. If I create the folder /mnt/iso and use mount /dev/sdb1 /mnt/usb, it returns fuse: failed to access mountpoint /mnt/usb: No such file or directory. If I create that folder, I get fuse: mount failed: Device or resource busy.

I get that error too sometimes. idk how to actually fix it I just reboot

I couldn't get it to work. I used windows2usb from the AUR instead.

Yeah, can't boot my USB disk using a Win7 ISO with this method. I'll try woeusb instead.

Doesn't work on me. Computer hangs trying to boot, I only got a flashing cursor :(

You need to set boot flag in gparted

I did that. Not solved that way.
Time has passed, I solved using a different software (I don't remember how, sorry)

windows2usb worked for me

pretty cool way of copying the ISO contents, thanks for the guide!

mount -o loop win7.iso /mnt/iso returns mount: /mnt/iso: mount point does not exist. If I create the folder /mnt/iso and use mount /dev/sdb1 /mnt/usb, it returns fuse: failed to access mountpoint /mnt/usb: No such file or directory. If I create that folder, I get fuse: mount failed: Device or resource busy.

All the commands are launched with root privileges. Try append to your command sudo.
