IT problems and solutions from our everyday IT life, worth writing and remembering. Knowledge should be shared, NOT KEPT!
Recently we encountered a weird case which had to do with Windows Server 2012 R2 booting. After having a “few” updates required for our Hyper-V and Backed Up we restarted the server.
Upon rebooting, BOOTMGR seemed to be damaged and we couldn’t get it run. For some reason (which was revealed later) the backup overwrote \windows\BOOT, due to faulty assignment of sata cables on the motherboard.
Thus, we tried out a few ways to recover boot files needed to get it back on the road again with the less possible collateral damages.
We tried 3 ways. All of them will be described below, apart from repair from CD/.iso tried already, which didn’t help…
For all below actions, you will have to boot from the equivalent OS CD / .iso and enter Command Prompt from the REPAIR list.
