I've install arch on a partition on my system (sda9) however my boot partition is not large enough to add the boot loader info for arch. It is only 100mb.
I need some help in being able to see Arch in my GRUB menu I can launch Arch from the menu as I do with the other OS's on the system?
Here is my lsblk info.
The boot/efi contents and the /boot from the /dev/sda9 folder.
Let me know what other info might be needed.

Maybe if I do it enough it would sink in.
Thanks for your help.
Please be patient with me.

you can start by removing all those unnecessary initrd/vmlinuz files, im guessing ubuntu ? that should clear up plenty of space, should be under add/remove kernels i think, havent used ubuntu in a long time.
EDIT: https://help.ubuntu.com/community/RemoveOldKernels , their documentation seems to be rather old, even when i was using debian before arch i was using 'apt' instead of 'apt-get' but hey it should still work fine.

I now have this .
What is next to do?
root@LM21:/boot# ls
config-5.15.0-83-generic grub initrd.img-5.15.0-83-generic System.map-5.15.0-83-generic vmlinuz-5.15.0-83-generic
efi initrd.img initrd.img.old vmlinuz vmlinuz.oldOnline
if you now have enough space then install your bootloader.
also you have "initramfs-linux.img vmlinuz-linux" in your /boot/efi which can be deleted too, they should be in /boot.
i see you also have the efi partition mounted to '/boot/efi' which would imply that you dont want /boot on the efi partition, which would save space too having your boot files on the root paritition (sda9).

All that sounds good.
If I put the boot files on the /boot on sda9 will that mess up Windows which is also on this system?
What commands would I use to accomplish this?
Thanks
Online
ok now im really confused, you say arch is on sda9 yet your lsblk shows root (/) mounted to sdb2.
Offline
Arch is installed on sda9 but I don't have a menu choice to boot into it.
I am booted into Linux Mint on sdb2.
Does that make sense?
Thanks
Online
ok you need to boot from the installation media and do the following in this order:
make sure that /dev/sda is in fact the correct drive as drive assignments can and do change, if the drive is sdb or some other then adjust following commands to suit.
mount /dev/sda9 /mntmount /dev/sda1 /mnt/boot/efiarch-chroot /mntgrub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=GRUBgrub-mkconfig -o /boot/grub/grub.cfgmkinitcpio -Prebootthat should work hopefully
EDIT: sorry missed a step, make sure to run grub-mkconfig as well, have updated the list

When booting to my installation media which is a arch installed on a usb flash dirve see this for lsblk:
All of the sda entries are the same as above except there are no mountpoints on any of them
I have sdc
sdc1 10M
sdc2 500M /boot
sdc3 3.3G /
How does that change the above instructions?
Online
When i got to the grub-install line it said
grub-install: error: /boot/efi doesn’t look like an EFI partition.
Online
so long as sda is the right drive dont worry about it.
post output of this from the arch-chroot where grub-install fails:
lsblk -f && fdisk -lEDIT: and i guess i should look at the fstab too:
cat /etc/fstabLast edited by jonno2002 (2023-09-18 07:19:48)

Ok i have a file with that info in it.
How do i get it here from the command line.
Do i use pastebin or something like that?

you havent mounted the efi partition, either you missed this step:
mount /dev/sda1 /mnt/boot/efior you need to create the dir first, here is the whole list again in order:
mount /dev/sda9 /mnt
mkdir -p /mnt/boot/efi
mount /dev/sda1 /mnt/boot/efi
arch-chroot /mnt
grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=GRUB
grub-mkconfig -o /boot/grub/grub.cfg
mkinitcpio -P
rebootEDIT: i messed up, this command should have been run BEFORE arch-chroot:
lsblk -f && fdisk -lLast edited by jonno2002 (2023-09-18 22:05:52)

rm /boot/efi/vmlinuz-linux /boot/efi/initramfs-linux.imgalso you have "initramfs-linux.img vmlinuz-linux" in your /boot/efi which can be deleted too, they should be in /boot.
should work after you remove those files

Ok I did read that but I thought I did all of that . I obviously missed that . Sorry.
That got me a little futher.
Now I got this error:
After running mkinitcpio -P

First thanks for sticking with me on this.
Ok that got me through the initial process .
The grub menu showed up but the only entry in it is:
UEFI Firmware settings as a choice.
That happened after I did the grub-mkconfig command
Online
did you run grub-mkconfig again after running 'pacman -S linux' ?
