Forums: 

i have Win 7 and Debian 8.5 on two different hard drives which I'd like to mount both in one computer. Do I need to modify the GRUB MYSELF in Debian or will this be looked after automatically when I boot up with both drives in the computer? Will l have to amend the BIOS and place Debian in first boot position?

If both hard drives are installed in the computer when you install Debian, all will work as expected -- Debian will detect Windows and configure an appropriate GRUB entry for Windows, and of course it'll set Debian up in another GRUB entry.

If you're reconfiguring after you installed Debian (meaning reshuffled/changed drives), then remember that you can boot off the Debian install CD in emergency mode, and get to a command prompt (the command "update-grub" will redetect OS' and reconfigure GRUB) or to reinstall GRUB entirely.
