My partions are set up as such:

Disk 1
C: (XP Partition) - Primary Partition
D: (Vista Partition) - Primary Partition
G: (Extra) - Logical Partition

Disk 2
H: (Backup) - Logical Partition

I have noticed though that when I boot into Vista my Vista partition is listed as being the C drive and XP is listed as the D drive, but I assume that only has something to do with the fact that I booted into Vista. When I boot into XP it looks as listed above.

My bcdedit.exe looks like this:

When I first edited this file I had put XP to boot from partition C:, but this caused XP to not be bootable from the startup options. When I noticed that Windows Explorer listed my XP partition as D: while booted into Vista I changed my boot.ini file to reflect this and was then again able to dual boot. The only problem I'm getting is the NTLDR missing error and even that goes away if I have a system disk in my CD drive. Hope this information is useful.
