*If not… we suggest a final attempt to fix this before re-installing!! Now your server should be up and running!! If Bootmgr and Boot folder show up in the list, you did well!įinally execute the below list of commands to update the BCD fileīcdedit /store c:\boot\bcd /set device partition=c:īootrec /fixMBR “D:” will stand for our CD-rom /.iso mount folder in this case.Īt this point you should check that files are correctly copied using the below command Now we have to copy all missing files to the selected BOOT particion, command Robocopy will help us on that. Again there we go…ĭISKPART> list disk ĭISKPART>list partition The idea of the second attempt was to check whether the partition containing BOOT was there, and if so we could use Robocopy command along withBootrec and Atrrib to replace/plant the BOOT files at the correct location. On the other hand of course, you could choose “N” or NO and move on to try the rest possible solutions we describe below^^! If so, you obviously type Y or Yes and then reboot your PC… problem solved! D:\Windows Add installation to boot list? Yes/No/All: Successfully scanned Windows installations. If you are lucky (not like us) you will get the below message: This command will search for Windows installations not included in the Boot Configuration Data and then ask you if you’d like to add one or more to it. iso and enter Command Prompt from the REPAIR list. All of them will be described below, apart from repair from CD/.iso tried already, which didn’t help…įor all below actions, you will have to boot from the equivalent OS CD /. 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.
For some reason (which was revealed later) the backup overwrote \windows\BOOT, due to faulty assignment of sata cables on the motherboard. Upon rebooting, BOOTMGR seemed to be damaged and we couldn’t get it run.
After having a “few” updates required for our Hyper-V and Backed Up we restarted the server. Recently we encountered a weird case which had to do with Windows Server 2012 R2 booting.
