Complete Hard drive corruption, OS not working at all

[pronewb]

So I have a fairly new computer, and long story short, I failed to get an anti-virus software in time. Eventually I got a pretty malicious virus that corrupted my entire hard drive. I mean I was on the ie9 and then it disappeared along with all the other files on my desktop. Pretty soon(like a few seconds later) the start menu and everything it contains along with all the start up icons vanished. Some how I got a critical alert that has something along the lines of my cpu had reached critically high temps. My fan started buzzing like a nest of wasps. I turned off my computer, because I always act impulsivley. I restarted it, and I go into what seems the screen where you can choose to start windows normally or safe mode it, but it wasn't. The screen told my the OS was basically done with.
I dealt with some pretty malicious viruses before, but this one took the "lets see which code can destroy more stuff" award.
I've formatted a hard drive before, but it was on a toshiba. I have an HP dv7t win.7 64 bit. I just ordered a recovery disk.

My question was, can I format my hard drive through the recovery disk or must I do it from the Bios screen? I need to know so I can stop worrying about this upcoming semester. And when I format my hard drive, must I redo the partitions in terms of their sizes or is it an automatic thing? Im assuming that all of my questions will be answered once I boot from the recovery disk, or at least thats what i'm hoping for. Also does anyone think that this virus could have permanently damaged anything? I've never encountered one that worked so hard, so fast.

No I just got the recovery media. I'm hoping that doesn't make a difference? I was old this recovery disk would restore my computer to factory defaults along with formatting my hard drive.

There may also be a hidden recovery partition on the hard drive about 14GB in size.
