Dell Prec T5500 (Xeon E5504) with two 1T drives, 24G ram, NVidia Quadro NVS420


Windows 7 Pro 64 bit was installed first and works fine

SATA 0 is Win 7 Pro 64 bit , 1 NTFS partition
SATA 1 is partioned as follows
8G swap
200G EXT4 mounted as /
800G NTFS

I booted from Ubuntu cd, ran install chose manual partition scheme and set up SATA 1 as above.

Grub2 boots into Windows 7 with no problems and I can see/use NTFS partition on SATA1

When I try to boot into default Ubuntu the screen goes black and then loses video signal and nothing happens, doesn't sound like the disk is doing anything.

Grub for the linux boot is as follows
recordfail
insmode ext2
set root='(hd1,2)'
search --no-floppy --fs-UUID --set a05...yadayada....b7a
linux /boot/vmlinuz-2.6.32-21-generic root=UUID=a05....yadayada...b7a ro quiet splash
initrd /boot/initrd.img -2.6.32-21-generic

If I boot into Live CD I can mount EXT4 on SATA 1 partition and everything looks fine, e.g the files /boot/vmlinuz-2.6.32.21-generic and initrd.img-2.26.32-21-generic are both there and the UUID of that drive is the same as referenced in GRUB2.

Any ideas appreciated

Have you run
sudo update-grub from the terminal within the LiveCD?

Let's get a better look at your setup & boot process. Boot the Ubuntu Live CD/USB. Choose "try ubuntu without any changes", when the desktop loads come back here and do the following:

1. Download the boot info script. There is a link in my signature.
2. Once downloaded move the boot info script to the desktop.
3. Open a terminal and run the command
sudo bash ~/Desktop/boot_info_script*.sh

This will create a RESULTS.txt file on the desktop. Paste the entire contents of that file back here. Once pasted highlight all text and click the # sign on the toolbar to place code tags around the text.

See here (http://bootinfoscript.sourceforge.net/) for more info on the boot info script.

Thanks uRock and presence1960
I downloaded the bootinfo script, ran it from livecd terminal and Results.txt is included below I think I see the issue in Results.txt it's looking for /boot/grub on the wrong disk but not sure how to fix that.
I DID NOT run sudo update-grub first. Will this fix the issue?

There are two ways to fix this. Boot the Ubuntu live cd (10.04) and boot to the desktop. Open a terminal and run
sudo mount /dev/sdb2 /mntThis will mount your 10.04 / partition

Next in terminal run
sudo grub-install --root-directory=/mnt/ /dev/sda

Reboot without the cd and boot to ubuntu. Open a terminal and run
sudo update-grub

Or the method I personally prefer is to put GRUB on the MBR of the disk that has ubuntu (sdb). Boot your machine with the 10.04 live cd and go into BIOS. Set the sdb hard disk as first to boot in the hard disk boot order. Save changes to CMOS & continue booting the live cd. Boot to the desktop and open a terminal and run
sudo mount /dev/sdb2 /mnt

Next in terminal run
sudo grub-install --root-directory=/mnt/ /dev/sdb

Reboot without the live cd and boot into ubuntu. Open a terminal and run
sudo dpkg-reconfigure grub-pc When you get to the last window use the spacebar to deselect sda and then use the spacebar to select sdb. This will insure all grub updates go to the MBR of sdb.

Thanks so much for taking the time with this. So far no luck.

I tried option 1:

boot to Ubuntu 10.4 liveCD

sudo -s
mount /dev/sdb2 /mnt
(ls /mnt to confirm it's my ubuntu partition)

grub-install --root-directory=/mnt/ /dev/sda

This resulted in a Grub configuration identical to the one that Ubuntu created when I installed the OS and likewise fails to boot Ubuntu on sdb2 though does boot Win7 just fine.

When it tries to boot there is disk activity for a couple of seconds, then screen goes black (still showing signal) and finally screen goes into no signal mode, no disk activity.



I tried option 2
Change Boot order so system boots from SATA1 (sdb) first, then SATA0 (sda)
(confirmed this by unplugging SATA0 and booting, got the No boot device message)

boot to Ubuntu 10.4 liveCD
sudo -s
mount /dev/sdb2 /mnt

(ls /mnt to confirm it's my ubuntu partition)

grub-install --root-directory=/mnt/ /dev/sdb

Try rebooting, get Grub menu (hit e to look at it, same exact config as previous) fails to boot ubuntu, and boots win7 just fine. Double check it's using sdb Grub by disconnecting SATA0 and looking at Grub config via e, identical to all previous configs.


I'm going to try reinstalling ubuntu directly onto sdb2 with sda disconnected from the system entirely and will report results.

thanks again for taking the time

Ok....so it looks like it's a problem with Ubuntu 10.0.4 and Dell T5500 and/or the nVidia Quadro NVS420.

Found lots of problems with people trying to get ubuntu onto various incarnations of the Prec T3500 AND T5500.

To simplify things I tried an absolutely default install, reformat, let ubuntu pick partitions etc on just a single drive (sda) and the system failed to boot in exactly the same way. (i.e. disk activity for a few seconds then black screen, then no video signal.

adding nomodereset to linux line in grub got the system to boot. From there I assume I can get updated drivers (or live with the limited resolution until a fix).

So all the things that looked like Grub problems are most likely video problems. Odd that the liveCD boots up just fine with no video issues.

It was a video driver issue nomodeset fixed everything

Gritty details:

Removed SATA0 (Win 7 system with Grub bootloader)
Connected SATA1 drive to SATA0
Boot from Unbunu 10.0.4 LTS cd
Do stock install letting it format my drive, took all defaults on installation
System fails to boot, black screen, some disk activity, then no video signal, then no disk activity.

Reboot holding down shift to get in to grub
edit linux line, add nomodeset to end of linux /vmlinuz.... ro quiet splash nomodeset

System boots to login screen, lots of flickering/blinking
Login and run System/Administration/hardware drivers
system puts up dialog for installing nVidia accelerated drivers I took the recommended version

Reboot and all is well.

Shutdown
connect Win7 drive with grub as SATA0
connect Ubuntu drive at SATA1
reboot

invalid (or not found) UUID
grub recovery>

Grub fails as expected due to different UUID for SATA1
Boot to live CD
from terminal


sudo -s

mount /dev/sdb1 /mnt

grub-install --root-directory=/mnt/ /dev/sda

Reboot into Ubuntu

from terminal
sudo update-grub

all is fine

Can now boot into Win7 or Ubuntu

not sure about nomodeset but based on perusing the web it seems it doesn't hurt to have it so I put it in as default. Seems to be less flickering on login screen



sudo -s
nano /etc/defaults/grub

change
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"

change
GRUB_CMDLINE_LINUX=""
to
GRUB_CMDLINE_LINUX="nomodeset"

grub-update
thanks for the tips and help
