OK so I was trying to fix a friend's ssd so I connected it to my pc and I reinstalled windows on it, then I connected my ssd back and the windows didn't boot at all it showed me some error on boot so I booted windows installation from a flash drive and ran chkdsk wich fixed it, then after a reboot the windows showed the boot logo and then it just turns black, the monitor doesn't show any signal and when I try to boot into safe mode it does the same thing, I tried running chkdsk again on the windows recovery command prompt and also startup repair and other things in the recovery console and nothing worked, the chkdsk runs fine but doesn't find any problems and all the other fixes in the recovery console fail. I really don't know what to do anymore. I don't want to have to reinstall windows
