Multiboot problems

I have a test HD that is partitioned into 3 drives. It used to have 3 different XP Pro - type OS setups. I formatted the C: drive and installed Win7 onto it. When I rebooted, there is no multi-boot screen, but it boots right into Win7. I tried some of the suggestions in the tutorial section, but none address my problem. When I leave Win7 on the C: drive, then try to reformat the D: drive with XP, the XP install goes just fine until the first reboot, when that happens, it reboots straight to Win7. I did it again, but in bios, I set the computer to only boot onto the CD (instead of hitting F12 like the last time). When I re-formatted the XP drive (D:) and it does the first reboot, it gives me an error message of missing operating system. Any ideas? Also, my third drive (E:) contains an operational XP system. Will I be able to get that one back?

Do you have some tools like partition manager? (I like the one by Acronis called Disk Director)

You will want the C: partition to be marked as active, and you want all partitions to be primary partitions (not extended or logical partitions).

If you have multiple drives, make sure any jumpers are set correctly.

You might also try a tool called Vista Boot Pro. It can help fix the Windows XP and 7 bootloaders without messing with command line.
