Windows not booting after deleting hiberfile.sys

I had problems with my SSD and I had to check and repair the disk through a Linux live USB. To do it I encountered the problem it could not run fsck because of windows hibernation, so I deleted the hiberfile with

mount -t ntfs-3g -o remove_hiberfile

Disk repair went successfully then, but when I try to reboot my windows 10 it fails with error code 0xc000000f.

What happened? What can I do to repair windows without having to download their ISO again?

The 0xc000000f error on startup means that the bootloader did not find the BCD file, which is the database for all boot-related options and settings.

Although there are methods for fixing the BCD, I would rather suggest to create a new Windows installation media on another healthy Windows 10 computer, and use it to repair the startup code.

For details see the article How to Run a Startup Repair in Windows 10.

There is no guarantee the disk can be made as good as it was before the problem happened. I would suggest to have a look at the SMART data of the disk to see if the disk has suffered a catastrophic error and should be replaced.

I would suggest first, before doing anything else, to use Linux to backup all data for which you don't already have backups.
