Hey Ubuntu forums, here comes a active member to the community since I'm going to use Ubuntu as my main OS.

WELL my native hard drive failed, so I'm going to go buy a external USB hard drive from RadioShack sometime this week. I installed Ubuntu 10.04 on my usb flash drive last year and still have it. It works for my other 2 computer but it doesnt work with the one with the failed hard drive anymore after the hardrive failed, I keep getting /dev/sr0: no medium found error. So how do I install Ubuntu to this empty external USB hard drive?
