Cannot log on after sanitizing hard drive

[leiterterry]

Pardon me for asking again, but it seems my last question with replies was deleted.
I have a hp 620 that initially had a problem with a virus on it. I looked for a way to either restore to a previous day or to set it back to factory specs.
One of the things I did was to sanitize the hard drive.

From then on it was all down hill. I am now not able to boot up I get a non system disk or disk error
replace and stirke any key when ready.

Now I had some people nice enough to comment and if I could get some explanations on their suggestions I could be back in business.

One suggestion was my reboot was in disrepair and he suggested to fix it.
If I could get a discription of how to do that it would be helpful.

If I could also get some help on how I could do a full system restore without a disk.

If I have to I will order one from HP. But would like to find out if there are other ways to purchase one without going through HP.

Thanks again for your help

You can buy a (legal) Windows 7 System Recovery Disk on Amazon.com for about $6, just search that name there. This is only a recovery disk and not a full system, but you need to get 32 or 64 bit version depending on your OS.
