Ubuntu 10.04, USB sticks and MacBook

[3fps]

I've got a MacBook 2.1 without a working internal harddrive. My goal is to run a ubuntu livecd from USB. However, as you may know, this is not easily done as the mac bios does not support booting from usb.

I've screwed around a lot with rEFIt on a small HFS+ partition on the beginning of the USB drive, but I have not managed to chainload linux. My next step was to do something similar to this

My question is, how is this done in ubuntu 10.04? Grub seems to be totally redesigned...

Thanks

Thanks for your replay, I must though admit that the information availible from that post is a little above my level. My question was more like; is there a guide for the same purpose (boot cd to usb)?

If not, can I download old grub somewhere and use stage2_eltorito and menu.lst to follow the guide for 9.10 i linked to?

Intel Macs, including the Macbook, can boot to USB.

10.04 includes a utility for creating a 'live USB' stick. See http://www.jonathanmoeller.com/screed/?p=1645 for details.

In essence, you boot to liveCD, and run the "Create a USB Startup Disk" utility.
