A while ago, as a way of researching and trying out new things, I installed Ubuntu on a second hard drive on my computer and made my PC dual-boot at start-up (GRUB2), choosing between the two OS's. Since then, I decided that while Ubuntu was certainly nice, I didn't really use it all that much and decided to get rid of it. So, I wiped my second hard drive clean and got rid of GRUB2. That seemed to do the trick, except that when booting up, the OS loading screen is *WAAAYYYY* slower and takes longer to kick in. It does, eventually, but it's driving me a little nuts that there's some kind of residual junk that's probably in the MBR or something that's causing this.
Question: is GRUB2 running off my motherboard or the hard drive? I ask because either today or tomorrow, I get my new hard drive to do a fresh install of Win7. If it's on the hard drive, then the problem is already solved. If it's NOT, however, and it's a problem that's on the motherboard, will clearing the CMOS and resetting BIOS do the trick? Does that bring BIOS back to its original factory version and I have to flash it again to the newest one?
Thanks a bunch.
