1. You saied, you're dual-booting Ubuntu, so please enter "sudo lspci -nn" and "sudo cat /proc/cpuinfo" on Terminal and post the results, this will give us detailed infos about your books hardware.

2. Your parameter is wrong, as rd=disk0 just defines a harddisk and is missing a partition, correct would be rd=disk0s1 for the first partition, on the first harddisk.

3. Please take your iphone or something and post a photo of the error message your getting "blah blah" isn't very helpfull in this case.
