Hi,
I did what you recommand and I now see my XP partition. The problem is that I cannot boot in XP. It says that there is missing files. I had to re-install the xp boot loader and then re-install 7. Am I the only one who had this problem?
Thanks
Thanks
Great, thanks!

I have another trouble – after access from Win7 my WinXP was ‘dead’, means most system applications won’t to load (I just run task manager, but explorer and etc couldn’t run).
That fixed the problem. Have been searching for a solution for a while, thanks.
brilliant.
Thanks a lot :D
wow, that works….it was a new drive and i had formatted and partitioned it and had about 80gigs that did not show up…i found your blog and tried the fix and it worked….wow…thanks
This works great. Fix my problem. Now I have all my partition recognized by Windows. Thanks !!! :)
thanks so much, windows 7 didn’t see my secondary partition cause of an error in the name. this one fixed. great! windows 7 is very cool
Right clicking the hidden partition (which has vista installed) only gives the,’delete volume’ option. Now what?
thanks so much, i accidently set my new partion for w7 as logical, no primary, didnt click till i had 7 installed, and couldnt find my drive, this was very helpful, all my drivers etc are on the the now unhidden drive.
