Upgraded to win 10 from win 7 online and there was an automatic update to win 10 a few days ago and the next time i restarted the desktop I am now stuck in a bootloop

computer specs are at bottom of this post

system restore does not work.... "need to specify which installation to restore" but no options are available

automatic repair does not work

reset this pc tells me the drive is locked

pulled the drive and mounted it to another computer and ran chkdsk /f on it, it made some repairs and when i reinstalled it and tried to boot, i'm still getting the same problem.

when i run chkdsk /f a second time , no errors are found

used rufus software to load windows 10 iso to usb drive but it does not work....seems like it's not booting from the usb.

used win 10 media creation tool to create a bootable usb drive from win 10 iso, will not boot from usb drive

created a win 10 dvd from iso and it will not boot from dvd

cannot enter bios thru startup for some reason and on the troubleshooting advanced options section, there is no option for startup settings to get to bios that way.

going back to previous build does not work

system image recovery failed: system cannot find file specified (0x80070002)

System File CHecker tool from bios tells me: " there is a system repair pending which requires reboot to complete" but i've rebooted 10 times and nothing changes.

when it attempts repairs and fails, it always takes me to a page asking what language my keyboard is, i select US and then it takes me to the troubleshooting page.

how do i fix this boot looping problem?
