Windows 10: CRITICAL_PROCESS_DIED after fixing mbr

I wanted to delete a dualboot Windows10/Linux to only have Windows. I forgot (It was some years ago) that I configured it to boot on the drive with Linux where they is grub, and then from grub automatically boot into Windows (or choose to go on Linux). So instead of just changing the boot order I used a CD installation of windows to use the command

bootrec /fixmbr

bootrec /fixboot

bootrec /rebuildbcd

But then, when I start my computer I have a blue screen with the CRITICAL_PROCESS_DIED error, and I can't boot even in protected mode. What can I do to boot again on Windows?
