 Posted: Sun May 28, 2006 1:11 pm Post subject: grub fills screen on new install .. {SOLVED} |
 |
|
I'm in the process of installing Gentoo again on my server (swaped a BUNCH of hardware, now it's freshen up time).
I did my usually Jackass install, edited grub to fit the hard drives, emerged the basics, and rebooted .. to ..
| Code: |
grub grub grub grub grub .. ...... until the screen is full
|
Little fdisk for ya:
| Code: |
livecd / # fdisk -l
Disk /dev/hda: 1083 MB, 1083801600 bytes
16 heads, 63 sectors/track, 2100 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes
Device Boot Start End Blocks Id System
/dev/hda1 * 1 497 250456+ 83 Linux (/boot)
/dev/hda2 498 746 125496 82 Linux swap / Solaris
/dev/hda3 747 2100 682416 83 Linux (/home)
This disk has both DOS and BSD magic.
Give the 'b' command to go to BSD mode.
Disk /dev/hdb: 20.5 GB, 20525137920 bytes
255 heads, 63 sectors/track, 2495 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/hdb1 1 2495 20041056 83 Linux ( / )
|
Here is my grub.conf
| Code: |
timeout 1
default 0
fallback 0
splashimage=(hd0,0)/grub/splash.xpm.gz
title Gentoo Server
root (hd0,0)
kernel (hd0,0)/vmlinuz ro root=/dev/hdb1
|
I've got two more hd's yet to go in (Big storage hds)
I've ran grub a couple times .. grub > root (hd0,0) > setup (hd0) >quit. No errors, just the plain ext2 stuff on boot.
It's been a long time since I had an issue with grub, I've been hammering away with Gentoo on my server for about two years.
Thanks much,
Justin

The repeating "GRUB" problem means that the harddrive geometry in your partition table doesn't agree with what the BIOS wants.
Most BIOSes use LBA by default, and set the geometry to 255 heads, but your partition table is setup for 16 heads.

The easiest thing to do is to change the BIOS settings to 16 heads, and then it should boot correctly.
If this is not possible with your BIOS, then you will need to repartition the harddrive, and force the correct geometry (and then restore the harddrive contents from a backup).
| Code: | | # fdisk -H 255 /dev/hda |
