I have a pc that has Windows 7 on it, and a hard drive that I recently installed and put Ubuntu 12.04 LTS on.
The problem I encounter is that grub does not load Windows 7, and gives me an error when I try to load from grub. Instead I have to go to the bios and select the other HDD in order to get to Windows 7.
Ideally I would like to be able to use grub to decide which HDD to boot. However, even another boot-loader that allows me to select which HDD to boot would be nice.
