Ubuntu problem on PS3

So I recently decided to but Ubuntu 7.10 Gutsy onto my PS3, but, as expected, it didn't work out.

I have already partitioned my PS3 with OtherOS and burned Ubuntu onto a disc (I'm sure it is the one meant for the PS3, since it was on the site I used) and popped it into the PS3, and then came to the Kbooter which it is supposed to. Except instead of just prompting me to install, I got this message:

(not my picture, but the same error)

And I have no idea how to get it to find rootfs. If anyone could help, that would be awesome!

Thanks.

hmmmmmmm tell he how it works, and what are the advantagesoh outing ubuntu?

English?

Don't want to sound silly... but have you checked with the http://ubuntuforums.org/ people?

They are a great help - the level of free service received from them beats any commercial contract you will ever pay for... but you probably know that, just wanted to make sure...?

Yeah I checked out their forums and tried all their tips to the problem, but none of em worked =/ I'll give it another look though, thanks.

Try Hardy Heron?

Also, are there any other alternative Operating Systems that allow use on the PS3?

oh sorry lol, i was on my ipod last night, lol, what i meant was what are the advantages of putting ubuntu on your ps3, i heard about it, but i dont see anything different, lol

ok i got this error at first and this is exactly what i did

press the "enter" key on your key board

It boots Linux onto your PS3, so it could be like a computer basically. (Linux is an open source operating system

I tried that when I first got the error, nothing happened =/

yeah i know what linux is, i tried booting it on my computer, but didn't like it, lol
