Boot Fails windows 10. Disk Locked seen in Repair PC.
Posted on 2016-10-05
Upgraded to Windows 10 Pro from Windows 8.1 Pro. System motherboard MSI NF980-G65 a gaming board. Run C:\ drive as a Raid 5 array with 1.36TB.
Ran several months productively but with lots of updates from Microsoft. Two weeks ago lost boot capability - unavailable system.
From system recovery disk entered command prompt. Ran C: Chkdsk /f == no errors found. Ran C: dir, all software on C: is as expected (windows, system32, etc). Ran most of DISKPART.EXE series of commands to observe DISK 0 (system) and Partition Volumes status. Attributes of Disk andeach Volume show all NOs for parameters.
Suspected Read-only status but parameters show none. Tried resetting boot record for C:/Windows/system32 drive using BCDBOOT.EXE and bootrec /fix and bcd commands. Both techniques show same failed boot.
Ran Attributes Disk Clear / Set Read-only command but they fail with cannot Clear / Set Read-only. However, Attributes Volume Clear / Set Read-only works ok.
Net: Looks like the BOOT DISK is locked and cannot fix it. Malware or other blocking may be happening but can't prove it.
Tried Repair PC recovery. It fails with "Disk Locked" status.
