Well, since you can boot with Live CD’s, I’d first check to see if the HDD is still good. Hiren’s may be able to check that for you. If the HDD is in good condition, then a malware expert will be contacted for you for other ways to restore your system back to working order.
Let us know. And first back up all your personal files on at least two different media that you wish to keep, if able, before proceeding.
