Using a 2012 Arch Linux release from a CD/DVD or USB stick:# mount /dev/sda5 /mnt #Your root partition. # mount /dev/sda3 /mnt/boot #Your separate boot partition (I assume). # arch-chroot /mnt # grub-install --target=i386-pc --recheck /dev/sda # grub-mkconfig -o /boot/grub/grub.cfgMostly taken from here.You're welcome.Don't forget to mark it as solved (by editing the first post).

I recently did a major number of updates of my system. One of the updates must have been to Grub, because after I restarted and grub came up, it wouldn't boot my other OS correctly, Archlinux.

Grub menu.lst help 29 weeks 5 days ago

Grub can boot from any partition so there is no need to share boot partition.

I tried to install Arch Linux onto an external hard drive, I made a root partition (ext3), and a little swap space. I flagged the root partition "boot" and I installed the grub loader onto the dev/sdb/ (not the root partition). Looked like a successful installation, but when I restarted grub was loading and quit part way with the Error 17: cannot mount selected partition...

That is, can grub use a /boot which is formatted as fat 32?The usual set up, I think, is to mount the efi partition at /boot/efi.

Hi,

Im on a HPG71, 9.10 fresh install, dual boot with Windows7 installed 1st. Jaunty/ grub works fine on 2 other machines . . . not Karmic. Im mainly a GUI guy. . . .

Below are the recommended outputs I have seen asked in threads.

This gets me in manually everytime (for two weeks): 1. ls 2. set prefix=(hdX,Y)/boot/grub

Do have a /boot partition so am a little confused as to the LINUX ../vmlinuz-linux line after reading this threadRealative paths are relative to the directory containing syslinux.cfg. So ../vmlinuz-linux should be correct.
