Surface Pro2: Stuck with locked disk after win8.1->10 upgrade

Current situation: MS SP2 that does not boot, and the ssd is not formattable because it seems locked (same lock as when you hibernate the pc)

I tried to upgrade from W8.1 to W10 with the upgrade tool in Win8 on a MS Surface Pro 2.

The computer hangs on 56% so I reboot. It tells me "the installation is failed, so go back to win 8". I accepted.

From there it showing infinitly "Restoring previous windows version".(It shown in dutch, so maybe it a bit different in English.

It is in this state for a month now and I tried everything listed below. Maybe you can help me

I tried creating a Win 10 disk, and do a fresh install from there. Result: Cant get the drive to boot

Tried creating a Win 8 disk. It boots, but it won't let me format my C-drive. It seems to be locked because it failed the recovery to the old Win8 install. I can remove all the partitions, but it gives an error when I try to install on a newly created partition. After a reboot, all partitions are back.

I tried booting to command prompt with windows 8 usb disk and remove the partitions with diskpart. It failes the format command. "attri disk" does not show read only

I tried an ubuntu live disk. It does not show my NTFS partitions

So the problem is:

• I can not access my data, but I accepted it is lost (and I copied some things via command prompt)
• I cannot get into windows
• It wont let me install windows
• I cannot format my harddrive
• I can not remove the harddrive because I cant open the tablet without breaking it.

Its now a very expensive brick. I hope you have some tricks to help me.

One of the things I thought is to make a USB with win10 running on it, but most of my flash drives are to slow and booting from a Sandisk extreme 32gb seems impossible.

Have you disabled secure boot? See the following

How to turn off secure boot in Surface Pro windows 8 | Microsoft Surface tablet

Yes. I disabled secure boot. It boots the windows 8 boot disk, but anything I want to change to the partitions is blocked somehow.

Same goes for access via Linux, drive is blocked.

I just want to format the drive and install windows, because my surface is dead now. Hope you can help me.

Have you tried the following?

Fix - The drive where Windows is installed is locked

He did it on a virtual drive, but the process should apply as well to your actual drive.

I tried these options.

I got the response from: "sfc /scannow".

"There is a system repair pending which requires reboot to complete. Restart windows and run sfc again".

Any ideas?

Have as look at this guide:

It's the most comprehensive one for trying to get out of an automatic repair loop. Try the bcdedit one for preventing the repair loop. If that doesn't work, try the other ones for a gpt/uefi device.

Thanks,

now tried sfc /scannow /offbootdir=d:\ /offwindir c:\windows (hope that d:\ contains system files)

Now its showing for 20 minutes "Beginning system scan. This process will take some time".

How long should this take? I dont see any counters.

Can it be that some of these tips dont apply if you boot from a recoveryusb?

bcdedit /set {default} bootmenupolicy legacy does not do anything on reboot (pushing F8)

Can't imagine it would make a difference whether you booted from a recovery USB flash drive or from a recovery DVD running on a bootable external DVD drive.

What keyboard are you using? The type cover? See this
