CRC error system halted


CRC is a "Cyclical Redundancy Check", sort of an error checking service,
like ECC... and typically means that there's issues either with your
hard drive, or RAM... though there appears to be other possible causes,
including a bad CD burn, and failing CD drive.

Try following the directions here:
https://help.ubuntu.com/community/HowToMD5SUM
to verify that the image wasnt corrupted, then verify that the CD burn
went well.

If everything checks out there, then try running a memtest (use the
'test system memory' option from the liveCD menu) and see if it returns
errors... If it does, then that means your RAM is flaking out, and
you'll need new RAM.

If memtest doesn't return any errors, go to the manufacturer website of
your hard drive, download their os-independent drive-checking tool, and
boot with it, and run a check of your drive.

best of luck!
