The issuew u describe remind me of grim days...
Tried all and every solution i could find.
About 2 days into this nightmare i was left with a corrupt OS, a bricked main BIOS, thank god mine has a backup BIOS built in.
What i did to fix it:
- clear cmos
- reflash older bios from backup, then updated from a usb stick.
- booted from a usb with win10 install media
- None of 4 drives could install, no idea why. 2 m.2 ssd, and 2 sata hdd.
- formatted 1 ssd, no succes. Had to wipe all of them before the installer would continue.
- when win10 finished installing, about 60GB worth of updates was done before all was in working order again.
Hope u have better luck!
And set windows update to only do security update automatically and nothing else. When a real system update comes it'll tell u.
