Fix boot Windows Server 2012 R2
Hi, I stuck at repairing boot on Server 2012R2, which initially stuck at Windows Updates, rebooted twice (so Last known Good is inbetween two reboots...lol), customer has no backups, and one proprietary software is installed there, which is PITA to reinstall. PROCEDURE: I must use install DVD to FIRST select Install wizard just so far to be able to inject RAID Ctrl drivers. Otherwise Windows installation is not found. Then I
CANCEL INSTALL and select REPAIR --> COMMAND PROMTP From command prompt I then TRY to repair boot with: bootrec /rebuildbcd ...but it fails, as it does not find any Windows installations. In order to workaround, I manually delete BCD record, then I repeat the above command, and this time it FINDS 1 Windows installation and does it's job. BUT after that, no Windows installations are
found. MAYBE, just maybe it is because this last update was probably major update, and manipulated BCD in such a way, that my 6 years old install DVD is not compatible with existing BCD on disk. Maybe. Reinstall and keep apps is NOT available. I am lost here...I know boot is damaged, but I am out of options. Web resources: http://www.howtogeek.com/howto/7728/troubleshot-startup-problems-with-startup-repair-tool-in-windows-7-vista/ Some Methods: Start Windows using Last Known Good Configuration. If you’ve just made a change to your computer that you suspect might have caused Windows to stop booting properly, starting with the Last Known Good Configuration could help. Start Windows in Safe Mode and then use System Restore to undo recent changes. Windows could freeze, stop, or reboot during the startup process because of damage to a driver, important file, or part of the registry. A System Restore will return all of those things to their last working order which could solve your problem entirely. You can also start a command prompt from the System Repair dialog box.
