My Superdrive is broken and I can't burn dvds. So, in order to install Ubuntu 11.04 on my Macbook Pro 5.5 I thought of booting from a USB disk and install it that way. I have tried using dd and UNetbootin but neither seemed to make the USB disk bootable. I have rEFIt installed and when the computer boots up, I get to choose from OSX, Windows 7 (I have a partion for that) and the USB disk with Tux as an icon. Once I select the USB disk is just starts Windows.
I even tried pressing F8 when it seems to load Windows and I get the Windows Boot menu, the thing is, it only shows Windows 7 as a boot option.
Is there any way I can boot up from the USB?
