So uh. Linux drive doesn't show up in boot menu. BIOS does recognize it, and Windows does too. Did I fuck up grub?

I haven't been booted into Linux for a few days, but have been using Windows. I did run chkdsk on an entirely unrelated drive (making sure to specify the specific drive) which I guess could have done something because of Windows strangeness

see if you can enter grub EFI from "UEFI shell" if you have it, or you can flash "super grub disk" on usb to boot linux
once you booted, run grub-install which should add it to the boot menu (which btw you can use efibootmgr to see from Linux)

#

I can't. GRUB isn't showing up at all

#

I suspect my only option is to boot into an arch setup environment and chrooting

loud burrow Sep 30, 2022, 10:23 PM

#

uefi shell is like a command line, not all bioses include it

#

super grub disk wouldn't require chrooting if it works

#

I've never seen the option in my BIOS. For reference it is an ASUS Prime X570-P

loud burrow Sep 30, 2022, 10:25 PM

#

oh ok, I have it on msi in the boot options

stiff light Sep 30, 2022, 10:25 PM

#

Ah, I don't. Only Windows Boot Manager and Enter Setup (which takes me to the BIOS)

loud burrow Sep 30, 2022, 10:26 PM

#

I'm not sure if I have it on that menu, I meant in the bios settings

stiff light Sep 30, 2022, 10:27 PM

#

Ah okay. Let me try and see, I know my bios does have a search feature

#

Oh wait there is something there

#

Would this do the trick?@loud burrow

loud burrow Sep 30, 2022, 10:29 PM

#

possibly

#

does it give you a list of FS and BLK

stiff light Sep 30, 2022, 10:30 PM

#

Warns me to disable secure boot. It is already set to other OS though so i wonder what's up with that

loud burrow Sep 30, 2022, 10:31 PM

#

I guess it can't be used with secure boot. so that leaves us with archiso or trying super grub

stiff light Sep 30, 2022, 10:33 PM

#

Guess I'm doing archiso then

#

Brb making USB drive

#

oh lol i literally didn't erase my last arch iso usb, guess that's positive lmao

loud burrow Sep 30, 2022, 10:42 PM

#

lol

#

can you boot it with secure boot enabled nowadays?

stiff light Sep 30, 2022, 10:43 PM

#

i mean nothing has changed since then and now so i should be able to

stiff light Sep 30, 2022, 10:44 PM

#

loud burrow does it give you a list of FS and BLK

It does when starting with the archiso usb actually

loud burrow Sep 30, 2022, 10:45 PM

#

thonk

stiff light Sep 30, 2022, 10:45 PM

#

Like if I boot the archiso i can get into an EFI she'll where it shows me blk

loud burrow Sep 30, 2022, 10:46 PM

#

oh nice

stiff light Sep 30, 2022, 10:46 PM

#

Now just to figure out which one is my arch partition lmao

loud burrow Sep 30, 2022, 10:47 PM

#

ok if you want that method then do ls FS0: for each FS to find the EFI partition, then FS0:\EFI\grub... with the EFI file

stiff light Sep 30, 2022, 10:51 PM

#

Okay, found the one with grub. What then? @loud burrow

loud burrow Sep 30, 2022, 10:51 PM

#

type the path, and enter

stiff light Sep 30, 2022, 10:52 PM

#

So FS4:\efi\GRUB\grubx64.efi in my case

loud burrow Sep 30, 2022, 10:52 PM

#

yep

#

I think it uses tab completion?

stiff light Sep 30, 2022, 10:53 PM

#

Yup that does throw me into grub as I know it. And yup it does

loud burrow Sep 30, 2022, 10:53 PM

#

cool

#

so it was just gone from the boot menu

stiff light Sep 30, 2022, 10:54 PM

#

Yup. I've managed to get back into Linux. Let's go ahead and rerun grub-install then. To the wiki i go

#

Looks like I'm good to go. Certainly efibootmgr shows grub as it should now so

#

Yup, thanks for the help!

yw!

trail citrus Oct 19, 2022, 2:27 PM

#

I am facing a similar issue

#

I just installed arch linux and ran grub-install and grub-mkconfig but the boot menu doesn't show arch's grub

#

it only shows my other distro's grub on a different ssd

#

i can boot to arch using that grub but idk what i will do after removing that distro
