Hello,

I am working mainly with ubuntu 10.04 64bits, sometimes with windows XP 

and I keep ubuntu 10.04 32bits as a "spare wheel"

Ubuntu 64bits hangs at boot and I have the following message when I 

start in safe mode:

> http://www.cijoint.fr/cjlink.php?file=cj201110/cijY98ZhkL.jpg

Kernel panic...the program hangs.

I start with acronis boot manager, I select the os, get the grub loader 

window and I get the mauve window with ubuntu in white , the caps lock 

and scroll lock   begin blinking and that's all. The white dots under 

ubuntu do not get red.

I searched on the web, tried to modify grub to propose 2 different 

kernels via ubuntu 32bits but with no results.

I also tried the boot repair cd...

I made a backup of the main folders (home, etc, opt...)

I think of reinstalling but before I ask whether someone can help me !

Thank you for possible tips.
