The other day at a customer I had the following problem
One of their physical machines had a problem starting. When trying to boot it went straight to System Recovery Options… not good
I tried all of the alternatives such as Safe boot, Last known good etc to get it to boot… no such luck ?
After some research I found the tip to rebuild the boot records using
bootrec /rebuildbcd. When I tried this I got the following information:
Scanning all disks for Windows installations. Please wait, since this may take a while… Successfully scanned Windows installations. Total identified Windows installations: 0 The operation completed successfully.
So the solution here was to remove the BCD store and then rebuild it like this…
First we back up the BCD Store:
bcdedit /export c:bcdbackup
Then we need to change change attributes on bcd folder in order to change it
attrib c:bootbcd -h -r -s
… and then we rename the bcd store to be able to replace it
ren c:bootbcd bcd.old
… and last but not least we recreate it

bootrec /rebuildbcd
Bootrec Rebuildbcd Total Identified Windows Installations 0 3
Hopefully everything is ok and we get something like this:
Successfully scanned Windows installations.
Total identified Windows installations: 1 [1] C:Windows Add installation to boot list? Yes<Y>/No<N>/All<A>: Bootrec Rebuildbcd No Installations Found
Which we respond Yes to and then reboot the computer

We've just had a Windows 8.1 Lenovo laptop that stopped booting. It reported attempting Automatic Repair and kept failing and rebooting through the same cycle.The advanced options after that has failed also gave you you a startup repair option. That wasn't able to fix the fault either. The usual fix under those circumstances is to go into advanced options, choose command prompt, then load Diskpart. From there you can fix the drive letter order if its got changed, remove unnecesary drive letters. Then fix the boot table using the bootrec command - often a chkdsk followed by deleting/renaming the existing Boot folder, then running bootrec /fixmbr, then bootrec /fixboot, and bootrec /rebuildbcd, will do the job. ![]() Bootrec Rebuildbcd Show 0The error reported was Total identified Windows Installations: 0 In the end the fix was from the command prompt option, but we had to go into C:WindowsSystem32Config and rename the registry files (Default, Sam, Security, Software, System), eg. default.bak. Then copy the replacement files from the Regback subfolder where there is a recent backup. The laptop rebooted with no bootrec tweaking needed.
