I installed Ubuntu 9.04 some months ago, and then installed Ubuntu 11.04 64bit a few months later without un-installing Ubuntu 9.04 (I assume it will have over-written the old version?), the computer worked fine (acer laptop) but I noticed a very slight reduction in performance from time to time. I logged on to windows as I have a partition and tried to open a file and the computer crashed, I was unable to move the curser etc. I restarted the computer and I got the message "error: no such partition. grub rescue>" From here I need help.
