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?
