I successfully installed the newest NVIDIA drivers (275.33) in Windows 7 64-bit and rebooted afterwards just in case. After the reboot, I got an error about missing MBR. I disconnected the slave disk so that Windows doesn't get confused and got this message:


It seems that Windows doesn't recognize the main disk anymore. I booted from Windows install disk but the main disk doesn't get listed as possible Windows locations to repair, and I can't get to it from the recovery prompt.

The BIOS does recognize it, and I'm able to see it if I run diskpart - however "detail disk" in diskpart says that there are no volumes on the disk. I also tried bootrec /FixMbr without effect, and bootrec /FixBoot which gives the error message:

Element not found.

What else can I do? Why would diskpart say there are no volumes on the disk?

Try some of the other Bootrec – Moab Jun 26 '11 at 15:30
Its possible the hard drive has failed, download the hard drive manufacturers utility to test the hard drive. – Moab Jun 26 '11 at 15:32
Moab, I did everything the Microsoft support article suggested. Didn't help. Disk and data is fine - see my answer below how I finally resolved it. – Domchi Jun 27 '11 at 1:50

In the end, while I haven't solved my problem (see my new question), I did get a bit farther. I used TestDisk from Hiren's Boot CD to recover partitions by following (more or less) this step-by-step tutoral. Afterwards, Windows is at least attempting to boot, and when I boot with Windows installation I'm able to access my data via command prompt, as well as from Linux/Windows XP if I boot from Hiren's Boot CD.

Since I have completely different issue now, it seemed to me that it's better to simply ask another question, with proper subject, keywords etc. – Domchi Jun 27 '11 at 5:19
