Grub disappears after entering bios [solved (?) ]

johane · 2017-11-06 13:42:10

My grub is completely gone after a visit in bios. I dont even have to change anything there, just enter bios and exit and my grub is gone.
The same thing happens if I turn off my computer, unplug the drive, start and turn off the computer and plug the drive back in. Grub disappears.
How can I avoid this phenomenon? It is quite boring to chroot and reinstall grub every now and then.
Other ditros grub like manjaro doesnt disappear.

UEFI? Dual boot with Windows?

Yes, uefi and dual boot with windows. But this happens even without windows.

https://wiki.archlinux.org/index.php/Un … boot_order have you tried this? If yes, are you sure the boot order in your bios is correct?

So the first thing we need to establish is that "BIOS" has nothing to do with this. That term has no place in UEFI at all.

Use efibootmgr; see what's there before and after you enter the firmware settings.

Both me and the OP meant the mobo's settings menu, referring to it as "BIOS" is just old habit, at least for me.

Not an Installation issue, moving to NC....

This is usual behaviour with a lot of UEFI systems, if the drive isn't present when booting then the relevant entries are deleted from the NVRAM. I'm not sure why this happens when you enter your firmware menu though.

Indeed. the proper terminology is 'firmware menu', which is applicable to both BIOS and UEFI systems.

Thank you all.
I have not done anything yet but it seems the problem has been "solved" by it self.
