My PC has 2 physical HDD

First HDD is 80 GB C: as Primary

Second HDD is 40 GB with extended partitions
D: 20GB Primary
E: 10GB logical
F: 5 GB logical
G: 5 GB logical
Currently have a dual boot.

I have WIN 98 on Drive C(primary)
I have Win XP on Drive D(primary)
Drives E,F and G are Data only(logical)

Want to keep the dual boot but want to split the C drive and move the
WIN XP to the split C drive and keep the D designation.

I do have an image of the WinXP drive (D)

Can this be done? Best way?

PS: all drives are formatted FAT 32

Thanks in advance
