- system recovery
- cmd bootrec with fixmbr, fixboot, rebildbcd, then chkdsk /r, sfc /scannow, ... without success

With bootrec /rebuildbcd give me error total windows instalation 0.
After another restart I have sometimes error depend of options I try, described in upper text:
- \BOOT\BCD, press ENTER and restart
- 0xc0000006b (00000000,00000000,0000000) and restart in loop
- lunch recovery repair or start windows normally if chose all of this two options win restart in loop

Anyone have a quick resolution of the problem or I need to reinstall win 7?

Thanks, I try this but the error is the sam, windows restarting in loop.
If I press F8 at startup and disable automatic restart, they give me blue screen with error PROCESS1_INITIALIZATION_FAILED
STOP: 0x0000006B (0x0000000000000000, 0x0000000000000000, 0x0000000000000000, 0x0000000000000000)

They make a crash dump and stop.

That error code happens when the Bootcat.cache file is corrupted.

Try this:

-Boot up with your Windows installation and get in to the repair console command prompt. Type the commands in bold.

-Type C: and press Enter
-Type cd Window\System32\CodeIntegrity and press Enter
-Type del bootcat.cache and press Enter
-Type exit and click Enter

-Click Restart and restart your machine.

Install Service Pack 1 on to your machine as this includes a hotfix to prevent the error happening.
