Windows 11 disk no boot

[Stanley1843]

I tried to install Linux on a secondary disk in my PC and after a failed Linux grub installation my PC didn't boot in Windows 11. I saw the message (Reboot and select a proper Boot device).

I made a bootable USB windows 11 and I run the below commands on the cmd but with no succeed.

DISM /Online /Cleanup-image /Restorehealth
The DISM.... command shows me the error 87.

sfc /scannow
chkdsk

bootrec /FixBoot
bootrec /ScanOs
bootrec /RebuildBcd
For some reason it writes(Total identified installations 0) like there no windows in the nvme disk.

How can I repair my disk?

did the linux installer say that grub failed?
you dont have secure-boot enabled in the bios do you?

[Stanley1843]

Yes the linux installer said that.
I have a secure boot as I saw in bios (attached pictures).
Now I have disconnect and the linux disk and the only disk in my PC is the windows 11 disk only.

Try boot repair disk. That used to fix mine a while back.
