 |
|
Hi all.
Having some issues dual booting into my Gentoo installation.
Grub gives the following error:
| Code: | grub> kernel /vmlinuz-2.6.12-gentoo-r9
grub error 13: invalid or unsupported executable format |
I was able to boot into Gentoo initially without any problems. I admit I was mucking around with the kernel in ways I shouldn't have.
After a little research on google, I decided to check the multiboot functionality of the kernel using mbchk. It returned the following message:
| Code: | #mbchk /boot/vmlinuz-2.6.12-gentoo-r9
/boot/vmlinuz-2.6.12-gentoo-r9: No Multiboot header |
Could this be the issue? If it is, how do I add the multiboot header?
I have run:
| Code: | | #make && make modules_install && make install |
I have also tried copying the bzImage /boot manually. Same issue.
Any and all help is much appreciated. Cheers. |

| Are you sure your boot partition was mounted when you copied your kernel? |

It should be. My Gentoo install is on hdc5, my boot on hdc0 and FC4 on hdc2. /dev/hdc5 has my Gentoo / and /boot. As you may have guessed, I have an extended partition /dev/hdc4. Swap is /dev/hdc3.
My /etc/fstab (more or less; booted in FC4 at the moment, writing from recollection):
| Code: |
/dev/hdc5 /boot reiserfs notail 0 1
/dev/hdc5 / reiserfs notail 0 1
/dev/shm /dev/shm tmpfs 0 0
/dev/proc /proc proc defaults 0 0
/dev/sys /sys sysfs defaults 0 0
/dev/hdb /media/cdrecorder auto exec,noauto 0 0
|
I wonder if repeating the mount and dump options for /boot is necessary in /etc/fstab. I would assume /boot would inherit these options from / as it is. As long as the redundancy does not affect anything, I do not see any harm done. Would anyone care to comment on that? |

Repeating the same partition on different lines in /etc/fstab is a big, red no-no.
The / line will be sufficient. |

Ok. Made the appropriate changes in /etc/fstab.
And that has not resolved the booting issue. And as I mentioned earlier, I was able to boot into Gentoo previously.
Any other suggestions would be appreciated. |
