I am trying to dual boot XP and Windows 7. I followed the directions I found on Windows 7 Forums and have both OS's installed. XP is on my C: drive (IDE) and Windows 7 on a separate IDE drive designated F:. Upon Boot, I am supposed to get a screen that lets me choose the operating system. However the screen, does not appear and I boot directly into the XP OS. The dries are on the same IDE cable, with the XP drive as the primary and Windows 7 as the secondary (no jumper). Do I need to make a change to the boot sequence in the BIOS? Does the W7 or both OS drives need to be on SATA drives as opposed to be the IDE drives? Thanks!
