Windows – When creating a bootable USB drive with Tuxboot, error “the file does not have a program association with it for performing this action”

The ms-sys command is important. With the -7 option it creates a Windows 7 compatible boot sector on your flash drive.

You can't use dd because ISO's use an ISO Filesystem such as UDF or ISO9660, where-as your USB drive only properly supports disk file systems such as ext3, FAT32, or NTFS

Would be better use rsync instead of cp -r ?

Not really. cp -r works perfectly fine. Just realize that NTFS handles permissions differently to Linux, so using rsync to keep everything intact doesn't matter too much. All that really matters is that the files from the ISO are on the USB and that the boot sector is formatted correctly using ms-sys -7

You can do all the steps as root if you want. The only 2 steps that really require root are mkfs and the 2 mount's

If you're getting permission problems even as root, you may need to mount your USB using ntfs-3g /dev/sdb1 as some Linux Distributions only supply a Read-Only driver for NTFS.

I managed to fix it by following the instructions at SevenForums.

So basically, if you have this problem, download PowerISO, format a USB drive, click Create Bootable USB drive, select the Windows Recovery Disc (you can download it online), boot from USB, click command prompt, and do what it says there.

For me, bootsect wasn't there, so I typed in Bootrec.exe /FixBoot and then Bootrec.exe /FixMbr like a link in that link says. Then I restarted my computer and it worked.
