Windows 10 no bootable device

I upgraded from windows 7 to 10 about 2 weeks ago, absolutely no issues, i was happy with everything.

My computer had froze and i forced a shut down via power button. Upon starting again i was greeted with "no operating system found"

I fixed that problem now im greeted with a black screen with something like "no bootable device found please detach any devices"

What i have tried is....

Made a win10 usb with the media creation tool from another computer.

Startup repair does not work, error is "the hard drive is locked"

I have tried with the command prompt the following commands

Bootrec /fixboot
Bootrec /fixmbr
Bootrev /rebuildbcd
*rebuildbcd tells me i have 2 installed windows os. One is regular windows and windows.old*
(If i say Yes to rebuild both of those, my media creation usb stops working if i restart. I get the error 0xc00000f and have to recreate the media creation tool on the usb. Otherwise i keep getting the same error)

I have also tried different sata ports on my motherboard, resetting bios settings, changing boot order, changed sata cable.


What else can i do?

On another pc, install macrium reflect free, and create a Macrium Rescue Drive (usb stick or dvd)

Boot from Rescue drive, Macrium will load, select restore tab,and click on 'fix windows boot problems'

It should list your OS.

Just click next, finish and it will rebuild boot sectors.

booting to win10 media and going to other ,will give advanced repair [boot option], to run bootup repair
