Hey... That worked. Wonder what was in the /usr folder....
Anyway. Doesn't look like it will work, since most of the services that is shown on the boot up list fails
If I understand, your system boots now but lots of failures.
It might be possible to recover the /usr folder from your dead disk.
Connect the disk as a slave drive. When booting up your computer, go into the BIOS and select NONE for the dead slave disk (tell the BIOS there is no slave disk there). Linux might be able to quickly copy the files from the disk.
The easiest thing to do might be to use the Live CD again.
Connect the dead drive as a slave.
Change the BIOS for the dead drive.
Boot the Live CD.
Attempt to mount the dead disk.
Copy /usr from the dead disk to /usr on your main disk.
A shell script to do this quickly may be a good idea.
