[CS-FSLUG] Ubuntu and busybox

If you are right, and it is booting into Busybox then the solution might
be much simpler than anything suggested so far. At the screen where you
are required to enter your password in the boot process, there should be a
way to make some choices about the session.  I´m not familiar with
busybox, but that option might be labeled ´session´. If you can choose
session, and then choose the ´x´ theme that you want, before you enter
your password, then when you go on, you will be in the more familiar and
flexible default ubuntu system.

Either way changing the order at boot is pretty simple in Grub unless you
have the new version of grub. If you can get a ´shell prompt´ (try
´control-F1´ or ´Alt-F1´ It slips my mind which, and I´m in an internet
cafe right now limited to windows <with a Spanish keyboard>, so can´t try
it to see which). Then type:

and when you get the prompt for your password type it.
then type ´gedit /boot/grub/menu.lst´

That sequence of commands puts you into a text editor as ´root´, and calls
up the menu list so you can edit it. If it calls up a blank page to edit,
then you probably have the new version of grub and <i can´t tell you where
to go from here. But if it calls up a text file you can edit it.  move
your cursor down until you find the lind: ´default 0´ and change the zero
to 1.  If you don´t find such a line add it in on a line all by itself
near the top of the file (perhaps all those lines that are commented out
by starting with #). When you reboot, it should choose the second choice
in the menu, which you give us to understand is Windows.

:One sinificant caveat: If you installed <ubuntu using ´wubi´ I haven´t
the slightest idea how to do anything with it.
