Still, grub won't boot.

What is on /dev/sda4 and /dev/sda5? Post parabola /etc/fstab.

When you boot your computer and access the BIOS firmware, are you able to boot either windows (Boot000B) or Parabola (Boot0010).

When you had the other Linux systems installed, were you able to boot each of them as well as windows from the Grub menu?

I noticed that in your efibootmgr output, all the Linux entries show the drive as GPT while windows shows MBR. Not sure what that means but it usually shows GPT for windows.

You indicate Grub won't boot either OS, so what exactly happens? Black screen, blinkng cursor, other??

sda4 is a primary partion for non-OS linux files: Source code Progs (not from package manager), vids, pics, etc.
sda5 is where I install linux distros

As root
root@parabolaiso ~ # cat /etc/fstab
root@parabolaiso ~ #

It's empty

As chroot in /mnt (sda5) while /mnt/boot is binded to sda1

[root@parabolaiso /]# cat /etc/fstab
# Static information about the filesystems.
# See fstab(5) for details.

Neither, only live USB

No, I switched between Linux and Windows from the BIOS/UEFI menu

Hard reboot and only, nothing else.

Without sda1 binded to /boot what is the contents of /boot as chroot?

Without sda1 binded to /boot and as chroot in /mnt (sda5)

Code:

mkdir /boot/efi
mount /dev/sda1 /boot/efi
grub-install --target=x86_64-efi
exit
reboot

Success!

I cleaned the /mnt folder before reinstalling just to be sure, now grub works but bare bones; No OSes detected.

My guess it is safe to run grub-mkconfig -o /boot/efi/grub/grub.cfg now, right?

colorpurple21859 · 05-26-2021, 09:08 AM

Code:

grub-mkconfig -o /boot/grub/grub.cfg

Don’t mount bind the efi partition to /boot. The grub folder on the efi partition is from when you was binding the efi partition to /boot and can be deleted.

GRUB is still not detecting OSes with this, or properly configuring GUI; Still bare bone

I tried this too
grub-mkconfig -o /boot/efi/grub/grub.cfg

Ended up breaking GRUB and reinstalled it again...

Did you install os-prober?

No; just followed the documentation.

How do I do that?

Note: I'm still new to pacman and only know how to use pacstrap for now; I already tried installing

Note: Nevermind, installed it as chroot. I can't use pacman in root in live media, only in chroot.

How do I work with os-prober?

colorpurple21859 · 05-26-2021, 10:38 AM

grub-mkconfig will call up os-prober automatically

MUSTDOS · 05-26-2021, 11:23 AM

Tried this again: grub-mkconfig -o /boot/grub/grub.cfg still, grub not configured

erased and reinstalled grub with efi, no config.
