Hello and welcome Jooshy Well not to put too fine a point on it my friend what you should have done was to burn a bootable Ubuntu disk when you boot from it you choose the non install option. I use this on quite a few occasions to solve hard drive problems when Windows will not boot or someone has lost their password.
However whats done is done. I don't know if that Ubuntu install would have wrecked the partition that is installed at the factory that you can use to do what is known as a factory default. Now if you are game you can try this > On power up tap F11 and it takes you into a repair install.
If the partition is gone then you are going to have to do what you are doing now. That being the case then you are going to have to keep at the driver site.
Also can you confirm that model number please as I cannot find any reference to the one quoted in the HP site. Plus can you give us a shot of the disk > Control Panel > Admin Tools > Computer Management > Disk Management and send the pic back so that we can see what there is on the C: drive. (see my pic)
