[QUOTE=Bare Foot Kid;1130079]Hello thenoo, welcome to Seven Forums!
Before we make any specific recommendations will you please post a snip/screen-shot of the entire disk management drive map with a full description as to which drive/partition is which, so we can see what you have going on as there may be a fairly simple way to resolve the situation.
Ok here is a snip of the entire disk management drive map attached.
This shows the situation with WIN 7 booted which is installed in the 20 Gbte Partition on the C: drive on the first of the two hard drives. The Unallocated Space of just under 15 Gbtes shown to the left of this C drive is where the XP OS is installed.
When XP is booted this becomes the C:drive and the WIN 7 drive is then shown as 20 Gbtes of Unallocated Space.
Hope this gives you the information you need.
