View Full Version : [ubuntu] 12.04 won't boot; AHCI problem

January 26th, 2013, 12:56 AM
I installed 64 bit Ubuntu 12.04 LTS and the computer won't boot. This is a Dell Precision Workstation 690 computer, which has a BIOS dated in 2006. It was running Red Hat EL 4 quite well. The Ubuntu installation proceeded without any problems. After installing Ubuntu 12.04, it has the following messages:
Controller Bus #00, Device#1F, Function#02: 00 Ports
No device found
AHCI BIOS not installed

I tried switching from AHCI to ATA in the BIOS, which eliminated these particular messages, but it still wouldn't boot.

Can anyone help? The computer is now essentially dead.

gbozo; Hi !

Try this and advise results:

Boot up ubuntu; as soon as the bios screen clears, hold the shift key-> grub menu;
In the grub menu select the "recovery" kernel-> choose "resume normal boot";
Do you boot to a GUI (degraded state) log in ?

just try'n to help
