Make sure you the hidden partition is NTFS!!!!
No responsibility taken if you follow these instructions and you fubar your disk. If in doubt, use a graphical tool like Partition Magic to help you out.
Open a cmd window
Type diskpart and enter
A seperate diskpart window kicks off with a DISKPART> prompt.
Find the partition you want to unhide using LIST and SELECT commands
DISKPART> list partition

I tried this and I couldn’t get it to work. It seems to work fine up until I try the SET ID=07. I have Win XP Home sp3, and there is no SET sub-command of the DISKPART command. When I try the SET ID=07 command I just get a list of valid DISKPART sub-commands. Is there something I’m missing?
Yeah, sadly a newer operating system! I would have been on vista or win 7 when i wrote that. The xp version suppprts a lot but not the set command. http://support.microsoft.com/kb/300415
Try gparted instead
neversleepz, thanks for the tip. gparted worked like a charm. I tried PartitionMagic and it couldn’t do it. Thanks again.
