I have a Windows 7 iso file which I wish to burn into a usb to make it bootable. I tried with the Disks utility "Restore Disk Image" and it copied the iso files into the drive but it didn't make it bootable. I tried using Etcher but when I selected the Windows iso file I got a message saying that Windows iso files required a special burning process to make them bootable and that I had to use a tool such as Rufus which isn't available for Linux and Wine couldn't run it properly.

I always use dd for this, and it has never failed. Yes, it works for Windows ISO's too.

Here's how I normally go about it (as root -or use sudo):

dd if=/path/to/your/iso of=/dev/sdX bs=4M;

The X in sdX is the where your USB device is connected. Be very careful tho choose the right one! Otherwise you might overwrite the wrong disk/partition.

One way to find out the right device is to issue ls -l /dev/disk/by-id/.

Below is an example, where you see that the USB device is located on /dev/sdb:

ls -l /dev/disk/by-id/

Edit: The Arch Wiki has a good guide for this.

    You can also use the /dev/disk/by-id/ names directly with dd. So just do dd if=/path/to/your/iso of=/dev/disk/by-id/usb-SanDisk_U3_Cruzer_Micro_3512330F5580ED45-0:0 bs=4M

  • the /disk/by-id/ is really great. Also for things like software RAID systems, fstab, etc. You always get exactly the drive you expect. If the drive is not there you will get a decent error message. While using /dev/sdX causes a lot of trouble if you replace the drive, or if you re-wire your drives. - The only real drawback is: if you clone your drive and replace it with the clone it will not work until you changed your config - but I like this sort of explicit handling.
