Basically, it was running slow so I tried system recovery, it failed half way and now it won't even boot. It says Ctrl alt delete to restart (hard disk error), but when I do it it keeps going back to the same screen with this message.
"Hard disk error" typically means the hard drive is faulty, in which case you need to replace it with a new one.
To double-check that the HDD has failed, you can test it from a bootable CD.
