Installing Ubuntu 12.10 on Laptop with Formatted Hard Drive

view story

http://askubuntu.com – My Windows 7 crashed so I formatted my hard drive. I wanted to try Ubuntu so I downloaded it and put it on USB following directions. It installs. I turn my computer off then rearrange my BIOS so HD boots first. Then it says no boot disk and wont load Ubuntu even though all files are on HD. What do I do? (HowTos)
