I have a system running Windows - works perfectly.
I decided to install Natty Narwhal on a separate hard disk (disconnected all other hard disks). After installing Ubuntu, I see the following message on the BIOS screen and the boot-up stops:
WARNING !! Now system is in safe mode Please re-setting CPU frequency
When I Ctrl+Alt+Del, it does not come a second time. But when I reboot via the Ubuntu GUI Shutdown menu, then that warning shows up again.
Any ideas on how to fix this?
Ps. I have in the past tried this with Maverick Meerkat, it has the same problem.
