Newly-built Windows 7 in Hyper-V shows black screen and flashing cursor after 1st boot

I have seen this happening a few times, mostly on Hyper-V guest machines.

The solution is simple.

Boot using the CD or ISO and press SHIFT + F10 to get a command prompt.

Type bcdedit and press enter

You should see the windows boot manager in one partition and the loader in another one. If that’s the case, then type:

bootrec /fixmbr and press enter
bootrec /fixboot and press enter
reboot computer

If that was not the case, try typing:

bcdboot C:\Windows

But make sure the Windows directory is in the C drive, if it is not, replace with the correct letter.
