I upgraded to 11.04 from 10.10 yesterday on a dual boot on a desktop system with Vista. Everything was acting fine until the upgrade. The upgrade appeared to be running properly and I went to do something and when I came back, the screen was black and I couldn't get any response from the PC. I reset the sytem. Here is the problem, on boot the GRUB menu appears normally(but with the 10.10 system displayed instead of 11.04) I can select the VISTA OS and the system starts normally. If I select the Ubuntu OS, I eventually get the following error:
init: udevtrigger main process (448) terminated with status 1 init: udevtrigger post-stop process (452) terminated with status 1 init: udevmonitor main process (447) killed by TERM signal
The disk drive for / is not ready or not present Continue to wait; or Press S to skip mounting or M for manual recovery"
All partitions are recognized by fsck -l. I tried to boot from a live cd of 11.04, but I keep being sent to the GRUB menu. Can someone help me get past this hiccup? It seems that GRUB didn't update and just needs to be directed where to look for linux package. I am just learning about Linux, but am willing to put some time into it. I just need some direction. Thanks!
