Hello, I am new to Ubuntu and Linux.
I am trying to install Ubuntu on to a computer.
It came with no operating systems.
It is a RAID hard disk or something. I do not know much about that.
I wanted to go to the usual routine of putting the install disk into the computer, booting off of it, and installing to the Hard Disk... but I ran in to a problem.
The computer boots only from devices with operating systems already installed.
I tried booting from the Ubuntu DVD many times, but failed.
I decided to install Ubuntu to a USB, boot from it, and then install Ubuntu directly to the Hard Drive from there.
So I went on a normal netbook, booted from the DVD, and installed Ubuntu to the USB. I followed the tutorial on the Ubuntu Wiki. It works fine.
The tutorial is at:
However, this tutorial says:
This tutorial must be very old, for GRUB2 does not have the menu.lst it used to have. I do not know how to change the boot references with GRUB2.You will also need to manually edit the menu.lst file of the new USB installation to change the boot references to /dev/sda, rather than /dev/sdb (or /dev/sdc etc.).
Although it says the step is not always necessary, I do not want to fail to boot into Ubuntu (Nor do I want to turn on the very loud computer too many times.) How do I change the boot reference in GRUB2 from sdb to sda?
