Hi. I am attempting to install Ubuntu 10.10 desktop on a Dell T7500 with two SAS drives in hardware RAID 0. Running from the CD works fine. The install process works fine. I have configured several different filesystems for /, /usr, /home, etc. The problem is that upon reboot after install, during initrd the system complains "ALERT /dev/sda1 does not exist dropping to shell". From within the initramfs shell I am able to mount all partitions successfully. Can anyone tell me what might be wrong or how to diagnose this?
