 Posted: Wed Oct 05, 2022 9:18 am Post subject: Pentoo&Ubuntu dual boot |
 |
|
Greetings to all, I had this issue for a long time now, I have googled and tried a lot of stuff but couldn't manage to configure this properly.
As a lot of instructions suggested, Ubuntu should always be installed second, since its logic is smarter in making dual boot work as desired, and that is what I did.
I have one HDD, Pentoo (based on Gentoo) was the first to be installed. Installation wizard created 3 partitions (I see these numbers from Ubuntu Gparted):
/dev/sda1 - fat32 - /boot/efi
/dev/sda3 - btrfs - Pentoo partition
/dev/sda4 - linux swap
Later, I have used Ubuntu live USB, opened up Gparted and took some space from sda3, left in without formatting. Then, I have started installation, Ubuntu recognized existing OS as Gentoo and offer to install Ubuntu alongside it and I chose the free space for it.
After rebooting, Grub is opened and I see both Ubuntu and Gentoo (Pentoo) options, but Pentoo just wouldn't boot (i will edit this post and include screenshot of error).
Running blkid in terminal, gave me this:

Running efibootmgr -v gave me this:

I have tried pentoo telegram group but I am getting godlike tier answers, but I am so far away from it with my knowledge.
However, when I am running Ubuntu, Pentoo partition is sometimes visible and sometimes is not and my current fstab file (when its not visible) looks like this:
| Quote: | # /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
# / was on /dev/sda2 during installation
UUID=ebc0a870-0408-477c-bbe1-eb0b1c9c30ba / ext4 errors=remount-ro 0 1
# /boot/efi was on /dev/sda1 during installation
UUID=9AF8-BEF8 /boot/efi vfat umask=0077 0 1
/swapfile none swap sw 0 0 |
Pls help, I need both since I am using Pluto+, GnuRadio and HackRF for my SDR tasks.
I need both since I can compare GRC packages and versions, as older ones have working Osmann blocks and Pentoo comes with all dependencies preinstalled. Also, I can run it easily everywhere from Live USB.[/code] |

Plz chroot into your pentoo via ubuntu and run
| Code: |
rm /boot//efi/EFI/Pentoo/BOOTX64.EFI
grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=Pentoo --recheck
exit
reboot
|
If successful in Pentoo run
| Code: |
sed -i '/PROBER/d' /etc/default/grub
echo "GRUB_DISABLE_OS_PROBER=false" >> /etc/default/grub
grub-mkconfig -o /boot/grub/grub.cfg
|
BUT

maybe you somehow messed your btrfs.
Plz post Pentoo's
/etc/default/grub

I found a way of booting Pentoo successfully, and here's how:
When Grub start menu appeared, I have chosen Pentoo installation, pressed E to open up boot commands and params. Last line was:
| Code: | | initrd /intel-uc.img |
However, I took a pic of the menu when I only had Pentoo and the booting was normal. I compared the two and found the difference at the last line, so I added it:
| Code: | | initrd /intel-uc.img /amd-uc.img /initramfs-5.18.13-pentoo.img |
After this step, I was able to boot into Pentoo correctly.
I was trying to use grep to find which file contains this command but couldnt find it. There is /boot/grub/grub.cfg file containing the same params, but this one should not be edited since its created by /etc/grub.d and /etc/default/grub
30_os-prober is the file that generates these lines in grub.cfg, but I dont know how to add these two images to initrd

At this point, my Pentoo boot dir is completely empty, probably run over while installing Ubuntu.
Thanks for the help (:

these two are mutually exclusive.
If /boot is /empty then where does
/initramfs-5.18.13-pentoo.img
reside?
Plz do this
| Code: |
Plz chroot into your pentoo via ubuntu and run
Code:
mount -a
rm /boot/efi/EFI/Pentoo/BOOTX64.EFI
grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=Pentoo --recheck

It was a little misunderstanding on my side, after googling how to mount Pentoo and chroot into it, it was clear and I have followed your steps.
After running
| Code: | grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=Pentoo --recheck
Installing for x86_64-efi platform.
Installation finished. No error reported.
|
I have Pentoo folders in both /EFI/ and /EFI/EFI.
However, after rebooting and opening edit commands in Grub meny, images are not there at initrd line.
When I try to boot after correcting it, I get two EFI stub errors:
exit_boot() and efi_main()
Now, my Pentoo /mnt/pentoo/boot/grub/grub.cfg looks like this:
| Code: | #

Ok you can safely remove the /boot/EFI files and only keep the /boot/efi/EFI ones provided that /boot/EFI does not contain the ubuntu folder.
Try
I guess you have two folders:One for ubuntu and one for Pentoo.
Ok now run from within chroot
| Code: |
### PLZ FIRST REBUILD YOUR INITRAMFS then
grub-mkconfig -o /boot/grub/grub.cfg
efibootmgr
efibootmgr -n <Pentoo-id> ### not really necessary to set next boot because you re-installed grub and by default Pentoo is the one to boot into.
exit
reboot
|
Hopefully you will boot into Pentoo.
