edit the grub boot sequence in Ubuntu 7.04 Fiesty Fawn

installed ubuntu 7.04 day before yesterday. this will be my 3rd or 4rth attempt at migrating to linux.

first thing, was to either write enable my other windows partitions, so i can continue my torrents from linux..

.. since i couldnt manage that, i decided to edit the grub loader and make windows vista the default os...

that wasnt as easy. i'd forgotten how i did it the last few times...

so for future reference am putting this here:

1) to edit the boot sequence, you need to edit the menu.lst file under root/boot/grub/

2) the file is of course write protected, the only way to edit it is with "root" priviledges. for the linux nooby, Root is like the default Administrator account on Win xp.
so log out and try to log in as root.....
didn't work? well thats coz the guys behind ubuntu realised, that allowing us noobs to log in as root was like giving a 2 year-old a stick of dynamite and a blowtorch.

3) anyway, your expected to use "sudo" (don't ask me what that is i don't know yet).....
don't know how to use sudo? then look online and findout yourself or... just read on coz i already went all over the web and figured out what to do :) .

4) heres what you do:

open a terminal ( that thing that looks like the command prompt in Win XP)

type this

gksudo gedit /boot/grub/menu.lst

hit enter

voila the menu.lst should open with save options enabled.

5) now at the top or near the top, theres this value:

default=0

this is the only thing you have to edit.

the "0" refers to the first OS listed in your boot list...by default ubuntu something or other.


just scroll down through all the mumbo jumbo untill you come to a list of all your bootloader OS options - something like:

linux....

linux safemode....

linux something or other mode...

non linux partition detected....

windows something or other...

note that windows is the fifth on the list here...
therefore go back to the top of the file and change
"default=0"
to
"default=4"

basically the entryies are numbered from 0 onwards... so 0 represents the first item on the list... and so on

thats it. save and close. now when you restart the system, windows will be the befault otion in the grub loader
