You should've burned the recovery discs when you first got the computer, but if you didn't, you should be able to get HP to send them to you for a small fee.
When you've gotten your system back like you want it, I urge you to get yourself an external hard drive and a good 3rd party backup program. You can set it up to do everything automagically at the time and frequency of your choice. 1 TB external hard drives are about $70 these days and a really good FREE backup program is the Easeus Todo Backup Free which you can download from
http://www.todo-backup.com/products/home/free-backup-software.htm . That can save you a lot of time and frustration the next time something like this happens. Sooner or later it happens to all computers for one reason or another.
Recently I was wanting to try Ubuntu alongside win7 just out of interest. I downloaded the iso and made a bootable flash drive and proceeded to use the wubi installer. I have 2 hard drives in my computer, the primary (where windows 7 is kept ) and a secondary (empty). I attempted to install Ubuntu specifically to my secondary hard drive to AVOID interfering with windows 7, but somehow that didn't work and Windows was ruined. I've installed ubuntu and other linux OS's many times before but never tried to install it to a secondary hard drive, and apparently that wasn't a good idea. I tried recovery but couldn't manage to get it back. After that I decided to just accept the loss and try to stick with Ubuntu. So pretty much what I have now is a freshly wiped clean computer that once had win7 and is now running only Ubuntu.
Now here's the problem: I want windows back like crazy. I mean Ubuntu is alright, but compared to windows its terrible. Is there any way to get it back at this point??? Am I going to be forced to put up with Ubuntu until I buy a new version of windows????
Here is my computer model and everything- http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01949110&lc=en&dlc=en&cc=us&product=4107708
The secondary hard drive is one I installed myself, its a 7200 rpm Seagate 200gb.
