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?

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).

Right clicking the hidden partition (which has vista installed) only gives the,’delete volume’ option. Now what?
