I installed Ubuntu and everything went ok. I did it by looking at this guide
Then when it boots from USB I get this error at the begining while booting
disk drive for boot is not ready yet or not present
According to this guide method 1 I went to
grub/grub.cfg (since in GRUB 2 its no more menu.lst) and changed all
/dev/sda as the guy says in his guide, but after these changes it still gives me the same error message. Can anyone help with this issue?
