Hi all. I have a problem with my windows server 2012R2(VMware). Someday, after reboot, i've got a message like this: an operation system wasn't found.
So i've found a post from here : https://social.technet.microsoft.com/Forums/lync/en-US/481f5a00-1b49-4521-9a3c-3e4ae5025d81/windows-server-2012-quotan-operating-system-wasnt-foundquot?forum=winserver8gen
and from here: https://neosmart.net/wiki/recovering-windows-bootloader/
tried all from there but nothing helped.
When i'm trying to do bootrec /scanos, i see 0 windows installations
Any ideas how i can repair bootloader?
Thanks

Sounds like something has broken with the hypervisor. You may need to ask VMWare what has happened.

Nope, i've tried to use another bootloader and it works fine
Might try booting the install media and Repair your computer

Yes, i've tried every method which I know to repair OS included from cmd: checkdisk, bcdedit, bcdboot, bootrec (also with delete old bcd and create new and write new bcd pointed to first partition), sfc /scannow, dism... but error still existing.
