Nothing really to work with here.

You’re going to need to provided errors, a log, something.

It wont boot is very generic. For all we know it’s powered off.

The server has been stuck in BIOS since restarting, unable to enter the system,no errors,So I cannot provide it. :joy:

Virtual or physical?

If it’s stuck at BIOS, that sounds like a hardware issue, so knowing if it’s virtual or not will help.

Have you powered it off and waited to see if a few minutes off helps?

  1. boot to a USB stick running Ubuntu and restore using the time shift backup that you definitely created. :wink:

  2. if you didn’t create a time shift backup, boot to a USB stick running Ubuntu and reinstall the GRUB bootloader
