Re-installing windows 7 from disk, have 3 un-needed partitions?

I tried what you said, but it is a bit too technical for me. I do not know what EFI bios means? I attempted to do normal install, but did not know when to hit shift F10 since when I tried it, it didn't work!

Go to step six in this tutorial:
Partition the Hard Drive in a Windows 7 Install

That's what the blue links are for. You click the one for UEFI BIOS vs. Legacy BIOS - YouTube to watch a video explaining the difference between UEFI and the old BIOS, so you can decide or ask back more questions.

If you want UEFI then you use this link for extra steps to install: UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with - Windows 7 Forums

If you don't have or want UEFI then just install normally proceeding with the steps I gave you.

Do you even have a UEFI BIOS? Check around the settings in BIOS setup, by tapping the key given for that on first boot screen.
