My desktop computer has multiple hard drives. Here's how they're currently set up: Note the Windows 7 loader on the XP drive.
My plan for 12.04 was to install it over my XP/Wubi set up and dual boot just Win7 and Ubuntu. However, I'm unsure about installing GRUB2. Is the Windows 7 loader required for me to maintain a dual boot setup? If I were to format sda and install GRUB there, would I have problems? I ask because GRUB on my laptop doesn't point to Windows 7 on some partition but rather the Windows 7 loader on some partition.
