View Full Version : [ubuntu] dual boot- boot screen

February 22nd, 2009, 06:25 PM
I have a dual boot system with windows and ubuntu as the two os.
The boot screen typically shows 4 options viz
ubuntu 8.04
ubuntu 8.04 (recovery mode)

windows xp

I tryed to use 1st option on the screen i.e ubuntu 8.04 but nothing happened.
so I have to use the recovery mode.
what is the difference between the two options ??????????

Also on my friends pc both the options work properly.
why this happens ??
is it because my processor is p4 and he has core2 duo ??????

what is the use of memtest option ??

Also I want to customise the boot screen .
I want windows to be the default choice after timeout and ubuntu should appear below windows.
how to do it (how to edit the master boot record of ubuntu) ??????

memtest is exactly what the name says it is. it checks the memory for any errors.

And to customize the boot screen as well as edit the boot menu you have to edit /boot/grub/menu.lst.
mine looks like this:

## ## End Default Options ##

# on /dev/sda1
#title Windows Vista/Longhorn (loader)
#root (hd0,0)
#chainloader +1

# This entry automatically added by the Debian installer for a non-linux OS
# on /dev/sda2
title Windows Vista/Longhorn (loader)
root (hd0,1)
chainloader +1

# This is a divider, added to separate the menu items below from the Debian
# ones.
