Missing a drive partition

I have a dual boot system with WinXP and Win7 on the same drive, partitioned out. I also have a second drive which contains most of my data files.

For some reason, Win7 isn't seeing my XP partition, however it has no problems seeing my data drive. XP can also successfully see the new Win7 partition when I boot into XP.

Is there a reason why Win7 can't see my XP partition? Is there a way to fix this? Doing a search on this was quite hard. I kept getting all sorts of irrelevant results (most about full missing hds which isn't my problem).

Hi again guice,

Win 7 does that on purpose. If you wish to see your XP partition while in 7, do this :

Boot into 7, go into Disk Management, right click the XP partition, and assign a drive letter - best accept the one it offers by default.

Good idea to reboot

Hope it helps

i got this problem too

on windows xp. i have 2 disks.

first disk, with 2 partitions ( C:/ and D:/)
second disk with 1 partition ( G:/ )

windows xp is installed on C:/

and i already installed windows 7 on G:/

ok, then i got dual boot...

when i use Windows xp i open windows explorer and i can see all partitions ( C:/ D:/ and G:/ )

When i use Windows 7 i open windows explorer I can see only C:/ and G:/

i already tried to change the D:/ drive letter but this option is disabled. can someone help me with this?

Assign a drive letter to the hidden partition under disk management while logged on on Windows 7 .

C:/ same as G:/ on windows xp
E:/ same as C:/ on windows xp
