After my computer restarted while upgrading through update manager (yes, I followed every troubleshoot I could find), I have decided to screw it and just start fresh. I downloaded the iso, and I've mounted it to my usb. Everything is ready. But now I am realizing I have NO idea what to do? Does it wipe my hard drive? Can I get it to wipe my hard drive? Will it override my old version? Will it get bogged down because of my old version? I have no idea what to do now. Please help!

Just boot from the USB and follow the graphical installation procedure. Same as windows. How more simple can it get? :) – Rrjrjtlokrthjji Aug 7 '12 at 20:21
@Nick how do I boot from disc? In previous attempts, I've used F-12 on the startup, but it never gave me an option to boot from disc. I'll try again and comment. – Robert Leonard Aug 7 '12 at 20:24
You could enter the BIOS and change the boot sequence , in your case set the USB drive as 1st device to boot . – Rrjrjtlokrthjji Aug 7 '12 at 20:26
While very tech-savvy, when it comes to Ubuntu, I've always been to lazy to learn everything. How do I enter the BIOS and change the boot sequence? @Nick – Robert Leonard Aug 7 '12 at 20:27
At the startup screen hit F1 or F2 (to me its F1) then go to Advanced BIOS Features -> Change Boot Sequence - > move the removable device(USB) first, hit F10 to save (or exit and select Yes to the popup dialog) and you are ready to boot.(Make sure you restore the boot sequence when install the new OS)) – Rrjrjtlokrthjji Aug 7 '12 at 20:30

I want to add that when you install, you will have the option to rplace or upgrade your current installation. You can also choose "something else" & partition manually. If you choose anything beside upgrade or install along side, yes, it WILL wipe your hard drive. So if thats what you want, its thaat simple. IF you want to keep your files, run an upgrade OR install it along side your current install.
