10.4 Boot problems after upgrade

[wbjr]

Hello,

I just used update manager to upgrade from 9.10 to 10.4
It told me it couldnt load all the packages but after a reboot i believe everything loaded. i was able to restart several times with no problem. Got the new desktop and everything. I left my parents house where i did all the upgrade and when i got home it wouldnt boot.
The laptop starts to boot up and when it gets to the Ubunutu splash screen a second or 2 later it flashes messed up little rectangles and then goes away and nothing happens.

I have replace the quiet splash with nomodeset with no luck
tried adding vga=771 didnt work either.

I downloaded the live cd and couldnt get any further with it.
I do have a few files on the laptop i would like to not loose if at all possible.
I can get to grub and tried recover with no luck either.
I can get a command prompt and see the hd partitions.

Thanks for any ideas.

I have the same problem after upgrade and I dont understand why Canonical ignore all of us who have this problem. I see posts evrywere of this problem but no explenation why and how to fix it.
I have an thinkpad R51 with intel graphics.

I have same problem, it asked if I wanted it to fix the problem on startup and it ended letting me go to desktop. Sadly a lot of the options like the "go to desktop" button don't work, no background and can't change from the crappy new theme. Now I can't even revert to how my system was when it was stable.

I am extremely mad at this stupid update, all they did was ruin my PC and put window controls on the left side.

I also have this problem. Both my laptops got partway through the update to 10.04, crashed, and are now not functioning.

I'm trying to boot off a USB key but I get the message "NO BOOTMGR"

What do I do?

-- Try the Super Grub disk - download and burn CDROM or Floppy version, it's what I use to boot:

-- May or may not work, but it should find Linux on the HD and try to boot it.

Has this problem been fixed? Can i safely run the update manager on my thinkpad r51 now to update to 10.4lts ? How do i find out?

If you know the difference between a drive sda, sdb etc and a partition sda1, sda2, sdb1 etc then there never was a problem. But many do not and the upgrade instructions that say to install grub to all drives and then they did present a confusing list of all drives & partitions. So everyone installed grub to all partitions overwriting the windows boot info in the windows partition boot sector.

I think the fix will be in the 10.04-1 release that will be out soon.

Only offer partitions containing /, /boot, or /boot/grub for
grub-install; installing to other partitions may have harmful effects
such as making Windows unbootable, and installing GRUB to every single
partition is likely to result in confusion anyway (LP: #576724).
