Windows system not recognized anymore RRS feed

    Hello, here's the situation :

    I have two hard drives : C and H.

    The C drive used to be my main drive containing the system. One year ago, I installed Windows on my second H drive and placed all the contents of the C drive in the trash and cleared it (some could not be removed due to lack of authorization, namely 3 folders : programs, program data, program files (x86)).

    It has been working fine ever since.

    When cleaning up my system yesterday, I decided to finally remove these 3 folders from the C drive. I boot up the computer from a Windows 10 installer on a USB drive and went in the command prompt to execute DISKPART and clear the C drive altogether.

    When rebooting, I had the "bootmgr is missing" message, even when disconnecting the C drive from my motherboard's SATA port.

    I reinstalled Windows 10 on the C drive and checked the H drive : all my data is still here, *including the system*.

    Strange thing is, the latter is not recognized my either the bios ("An operating system wasn't found [...] ") or the msconfig window.

    Any idea on why this was caused and how to get my initial system on H drive back up and running ?

    Thanks a lot for reading and taking the time to answer !
