Unable To Make Browsing Happen On A 64bit Windows 7

So, after going through every trick in the book, I was unable to make browsing happen on a 64bit Windows 7 (any and every browser would randomly hang the system completely), so my only option was to switch to 32bit.The first installation failed and got stuck in a black screen with a frozen cursor. After a restart the installer told me I could continue the installation after a reset, so I did that, only to be greeted with the same message. This happened over and over a few times, so I figured it's not going to work and I'll have to make a fresh install. Then something mysterious happens and I'm not yet sure what exactly happened. In any case, the end result was that I still had some of my 64bit installation remaining including some files I downloaded while trying to make it work in addition to my 32bit installation on my other drive (which I was not planning on formatting). The only explanation I can come up with is that I somehow managed to format the wrong drive, not once, but twice.

And this is where my current problem begins. I'd very much like to format the drive with the 64bit stuff, but Windows won't let me. I've tried doing it from the command prompt but it says "Access Denied as you do not have sufficient privileges. You have to invoke this utility running in elevated mode." I'm the system admin! How can I not have sufficient privileges? And what is "elevated mode"? Ok, so on we go to the Disc Manager. This time I'm greeted with "Windows cannot format the system partition on this disk.".Actually, now that I think about it, I suppose booting from the CD might do the trick. Still, for some reason the installer takes its time starting (was much faster in for the 64bit version) and I'm getting tired of playing with the boot order, anyway.So, I'm wondering if there is any way to format a disc with system files from another Windows installation without going through the CD boot.
