I have a Dual-Boot USB I created with Multisystem for booting into PartedMagic, Ubuntu 11.10 & Windows 7 Install. Problem is Windows 7 says it can't install on a GPT partition.
Googled, and found that I need an UEFI system (on ASUS H67M-PRO, supports UEFI BIOS, so this shouldn't be the problem). I also need to have the correct efi files. I find efi files in my USB, so I think that's fine. But I think the files might not be loaded or something?
So I am thinking, do I need to do something special to boot into the UEFI installer for Windows 7 or something? For that I need to configure the GRUB on the USB? How?
