Windows – Grub rescue command line, chainloading Windows 7 installer

bootgrub2intel atomuefiwindows 7

I currently have grub2 installed on a Baytrail tablet along with Ubuntu 14.10 (64-bit) and Windows 8.1 (32-bit). The tablet comes with 32-bit UEFI only firmware, and a 64-bit atom processor.

Using Grub2 (IA32) I can boot any number of 64-bit linux os's, but I've yet to find clear instructions on how to chainload a windows 7/8 installer using the Grub command line.

As of now, I have a (legally obtained) Windows 7 "Home Premium" recovery ISO made into a bootable USB drive.

Does anybody have clear and concise instructions on how to boot/chainload a windows 7 installer from a USB drive, using the Grub2 command line?

  • Just have been there too (where you are right now) And if you tablet is a Toshiba 10"... we are brothers in arms... ;-)

    Just add this entry to your GRUB2 menu

    menuentry "Windows 7" {
         insmod part_msdos
         insmod ntldr
         insmod ntfs
         ntldr (hd0,msdos1)/bootmgr
    }
