dual boot problem

Hi Guys

Please help.
I have installed XP in C (first) and win7 in D. Everything works fine. When I use win7 I can see and access to drive C (XP) but when using XP I cannot see and access to drive D (win7). What can I do to?

Thanks

Hello pvl10,

Welcome to 7 Forums.

See if the D drive has a letter while booted into XP. Info here. Hard Disk Partition Letter Missing in Windows 7 - Fix

Thanks Gary. Yes the drive D has a letter while booted into XP but I cannot access to it. In my computer it shows: Local Disk(D) but no file system and total size, free space.

Thanks RSVR85. I ve done what you suggested but then I could not boot into either XP or 7. I had to use Hiren CD to reactive C. Now I can boot into both Xp and 7 but still having problem as described above. Anyone has any ideal? Cheers

Do you have your Seven partition hidden from XP? You might have done this to prevent XP from deleting Seven's restore points.

See this Vista tutorial: Hide restore points, it works the same for Seven. Look in the XP registry (run regedit.exe) for the XP registry setting mentioned in the tutorial (.../MountedDevices/Offline).

WARNING! If you enable XP to see the Seven partition, XP will delete Seven's restore points. This is not a good thing.

If you absolutely must see some of the files in the Seven partition, you can simply (from within Seven) put them into a folder in the XP partition or create a separate partition that both Seven and XP can see.

CAUTION! Be very careful about using Seven to create and save files or even access files within the XP partition. Seven may apply its permissions to files it has accessed making those files unavailable to XP, it might even make those files unusable or undeletable from XP. This can cause XP to become unstable or even prevent it from running.

There are reasons that Microsoft did not allow upgrading from XP to Seven, the above reason is one of them. MS wants you to totally abandon XP and has made little effort to provide side-by-side compatibility between Seven and XP.
