 Posted: Mon Mar 16, 2009 8:02 am Post subject: [SOLVED] Wont boot after install. Grub seems to work but.... |
 |
|
Hi,
I installed Gentoo using the GUI on the live CD, and that went fine without any hitches. I used 3 partitions, 100MB /boot, 600MB /swap, 8GB /, as standard.
However, in order to get the Live CD to boot in the first place I had to bypass the ultrastor module ('gentoo noload=ultrastor'). Again, this installed fine and after installation I was asked the restart. So I did.
Grub starts up, says 'please wait...' and then hangs at a blank screen with '_' at the top.
Whevener I press enter after that stage, it starts to boot gentoo but with ALL the modules, so naturally it gets to 'scanning....ultrastor' and hangs.
Is there some way I can bypass this normally? I can't seem to get Grub to give me any boot options after installation.
Do I press a certain key? F1 has no effect.

Hi, did you put some splash image in your grub.conf? Something like this:
| Quote: | | splashimage=(hd0,2)/boot/grub/splash.xpm.gz |

No, I haven't been able to access any grub configurations.
I'm a complete noob to Linux, so maybe some help on how to edit grub without booting Gentoo first?
I've downloaded the RecoveryCD with all the tools on it, but I'm not entirely sure which partition to mount so I could edit the grub files. Do I mount /boot? or root? |

mounting boot of the rescuecd would be enough to edit the grub.conf file
using the handbook's grub.conf as a refrence:
| Code: | # Which listing to boot as default. 0 is the first, 1 the second etc.
default 0
# How many seconds to wait before the default listing is booted.
timeout 30
# Nice, fat splash-image to spice things up :)
# Comment out if you don't have a graphics card installed
splashimage=(hd0,0)/boot/grub/splash.xpm.gz
title Gentoo Linux 2.6.24-r5
# Partition where the kernel image (or operating system) is located
root (hd0,0)
kernel /boot/kernel-2.6.24-gentoo-r5 root=/dev/sda3
|
you can add to the kernel line so it looks something like:
| Code: | | kernel /boot/kernel-2.6.24-gentoo-r5 root=/dev/sda3 noload=ultrastor |
Since it sounds like you are not getting the grub menu you would want to double check the line 'splashimage=' as was said previously if the line is there make sure it is uncommented (remove the #) also check that a splash image is present in the directory, so if /boot is mounted to /mnt/gentoo
| Code: | | ls /mnt/gentoo/grub |
and look for splash.xpm.gz
mine looks like this:
| Code: | $ ls /mnt/gentoo/grub | grep .xpm.gz
splash.xpm.gz
|
(I used the grep command to cut out the rest of the files irrelevant to what we was looking for)

|

it just occured to me that my problem might be very similar to one of the grub stickies in the forum.
adding the noload=ultrastor line didn't work. I think grub isnt loading menu.lst. I'm gonna try that now. |

If after that the module still gives you problems the other option would be to chroot into your install and blacklist that driver to prevent it from loading at all.
If you need help doing that I will try and post a step by step for you.
also google found this segment:
| Quote: | | During boot of cd it got stuck on loading ultrastor and took me a while to find this was the on board firewire 1394...disabled from bios got me up into the install. |
you may want to try that and see if it lets you boot into your install. If it works you can then blacklist the module and re-enable the firewire from the bios if it is needed
EDIT: another thing, if all modules are getting loaded I'm guessing you are using genkernel, compiling your own would mean the only thing that gets loaded would be things you need

| Yeah, turns out it was splashscreen after all. I think that's like 30 noob points for me. |
