taken to initramfs when starting computer

[marcus aurelius]

after installing the 3 important security updates from yesterday, after the restart and successive logons to ubuntu, i'm taken to the initramfs screen and there is an alert saying that one of my partitions does not exist.

i've since re-installed ubuntu, but have not done any updates yet.

i'm using unr ver. 10.04
