You'll have to try and boot from the CD - rather than from the hard drive (because, I presume, that's the disk error that you're getting).
To do this, you'll have to provide more information about the make and model of your system.
Then, if you need directions for the hard drive test, you'll have to provide us information about the maker of your hard drive. If you cannot open your case to get at the hard drive, then I'd suggest this free test: http://www.hitachigst.com/hdd/support/download.htm#DFT
Read the user guide thoroughly, and ensure that you use an ISO recorder to put the test onto a CD. If you don't use the ISO recorder, then the CD won't be bootable - and you won't be able to boot to the test.
