WIndows 7 cannot boot - bootrec reports FS not found or corrupt

I solved the problem using diskpart to fix the apparently 'corrupted' filesystem ("... does not contain a recognized filesystem") and then recreating the BCD using bootrec.

C:\> diskpart
DISKPART> select disk 1
DISKPART> select partition 1
DISKPART> active
DISKPART> extend filesystem
DISKPART> exit
C:\> bootrec /rebuildbcd

Be sure to run chkdsk /f after booting to Windows.

I also suggest looking at the EasyBCD program. I have not tried it myself but it looks promising.

Just for the record, I had increased the size of my NTFS partition using Gparted, that's why I used extend filesystem in diskpart.

I had the same problem, I tried exactly the same solutions, and it didn't work.

Then I tried disconnecting all my other hard drives, leaving only the one with my Windows installation on it. I rebooted with Windows7 recovery disc, and ran the automatic repair, it recognized the drive and the windows installation (until I disconnected all my other drives the "System Recovery Options" list was always empty), and it said there was an error with that volume, and that it was successfully fixed.

I rebooted again, ran automatic repair again, and voila, everything was fixed and I was back in Windows.

Unfortunately, none of these answers worked. After 10 days of trying everything I could find and think of, I wiped the drive and reinstalled Windows.

I just had this same issue, which lasted for weeks. For whatever reason I decided to shrink Windows 7 and grow Ubuntu 10.10 using GParted.

Anyway, I followed the same steps you followed over and over again. The trick (and the fix for me) was after setting the partition active, also run RESCAN. Then, exit and run bootrec /rebuildbcd. For good measure I also ran the GUI boot fix. After a reboot, I was back in Windows.
