dual boot windows 7 and windows vista
First I had XP 64-bit running on first partition. Then I installed Vista 64-bit to second partition of the same HDD. Vista boot manager created entries for both XP and Vista and everything worked smoothly for last year.
Now the time has come to format XP partition and install Windows 7 on that partition. The bad thing is that I already did that, so there is no going back. Windows 7 runs smoothly from that partition even now.
But I can’t access the Vista anymore. Windows 7 did not detect Vista on the other partition and did not make me a boot manager entry for it.
I can not format or reinstall Vista, have there important things.
Vista partition isn’t even marked as System.
How do I revert changes to Boot Manager, so I can log in to the Vista again? And dual boot with 7.
