I boot ArcaOS installer on a USB stick, and to go the System Maintenance window. I'm not at an installer right now, so going from memory, I do the following
I enter Volume Management (Simple) or whatever to access the ArcaOS volume manager.
I rewrite the MBR (File menu?) Then I save changes.
When I reboot, Windows starts.
(On my X250, I tried a new hard drive, made the partitions and installed Windows. Now it's all working again. I still would love to know how to repair a broken installation.)
Hi, I did that. Boot with USB Flash, Maintenance Mode, Volume Magement, Rewrite MBR, Save, Reboot.
Airboot was gone, and on boot it only shows me a blinking cursor on the top. I guess it was trying to boot from the W10 partition.
On this sate I did:
1) Win10 USB Boot - Repair your computer -- Troubleshoot - Startup Repair. It failed and said "Starup Repair couldn't repair you PC".
2) Win10 USB Boot - Repair your computer -- Troubleshoot - Command line. (
Tried this)
- run chckdsk c: /f - just in case
- bootrec /FixMbr
- bootrec /FixBoot
-- Access is Denied
- bootrec /ScanOs
-- Scanning...
-- Please wait...
-- Successfully...
-- Total Identified Windows Installations: 1
-- [1] C:\Windows
-- The operation completed successfully.
- bootrec /RebuildBcd
-- Scanning...
-- Please wait...
-- Successfully...
-- Total Identified Windows Installations: 1
-- [1] C:\Windows
-- Add installation to boot list? Yes (Y)/No(N)/All(A)
Pressed Y
-- The operation completed successfully.
After all that, no Windows 10 boot.
I also tried the ""bootsect /nt60 sys"" on Win10 but I also get an "Access is denied" error.
After more reading I tried.
-- bootsect /nt60 sys /force
got : Bootcode was successfully updated...
-- bootrec /FixBoot
-- Access is denied.
Rebooted just in case.... Now I get.
"An Operating system wasn't found. Try disconnecting any drives...."
It still does not look good to find out what Airboot or ArcaOS did to break the Windows 10 boot.
