Unlocated boot problem
 
By the process of elimination I'm humbly lead to suspect a problem somewhere between HW and BIOS; because the same problem occurs with SATAa and SATAb. (And because there is no POST beep with new mobo bundle of components in my pc.)...

I have installed Ubuntu 10.04 twice now on SATAa but it halts during boot with:

Code:

Gave up waiting for root device: Common Problems:

-Boot args (cat /proc/cmd line )

Which returns...

Code:

BOOT_IMAGE=/boot/vmlinuz-2.6.32-21-generic root-UUID=45Fba1ab...
Code:

-Check root delay = (did the system wait long enough?)
(Yes I think it did)


Code:

- Check root= (did the system wait for the right device?)
(again BIOS seams set up ok)

Code:

- Missing Modules (cat /proc/modules; ls /dev)
These scroll of the pge.

Code:

ALERT! /dev/disk/by=uuid/45fba1ab-2864-4e2f-97a7-be780f8e355d does not exist. Dropping to a shell!


BusyBox v1.13.3 (Ubuntu 1:1.1.13.3-1ubuntu11) built in shell (ash)

Enter help for list of commands.

(initramfs)


On advice, I've edited the Grub menu several times; See:


"I don't see a problem with your results. (Of a Boot script.) I'd like you to try to boot by editing the menuentry from the Grub2 prompt.

1. Remove the entire "search" line.

Quote:
search --no-floppy --fs-uuid --set 45fba1ab-2864-4e2f-97a7-be780f8e355d

2. On the "linux" line, change the part "root=UUID=<long number>" to "root=/dev/sda1" with X being your Ubuntu drive and Y being your Ubuntu partition. Leave the rest of the line as is.

From:

Quote:
linux /boot/vmlinuz-2.6.32-21-generic root=UUID=45fba1ab-2864-4e2f-97a7-be780f8e355d ro quiet splash

To:

Quote:
linux /boot/vmlinuz-2.6.32-21-generic root=/dev/sda1 ro quiet splash

3. CTRL-x to boot."


I have also tried the edit:

Quote:

recordfail
insmod ext2
set root='(hd0,1)'
linux /boot/vmlinuz-2.6.32-21-generic root=/dev/sda1 ro single
initrd /boot/initrd.img-2.6.32-21-generic

But Ctrl_x doesnt lead to a sucessfull boot.

Now I find SATAb with a perfectly functioning os previously installed on another pc from the same live cd, halts on the same problem pge only with an Alert for a different UUID.

Doesn't that mean the problem is not with the SATAs?

Thanks for your interest.


My new mobo is GeForce6100PM-M2
