Re: factory reset

If there is no serious hardware issue, you can get into the computer again after the factory reset, so you can start working again.

One minor problem: you lost all you current work that you forgot to backup. To solve that, boot from an Ubuntu disk (free download and burn, see their site for instructions) and copy all those files to an external disk.

If there's a hardware issue and neither the factory reset nor Ubuntu work, you'll have to take the disk out and try to get to your data on that disk on another PC. If the broken thing is the HD, you'll have to pay a data recovery company to get it back.
Only time will tell what will happen.
