installing XP?

Somehow my Acer One netbook will not boot, giving error "NTLR is missing".

I cannot find & install NTLR but, I have XP home on a stick.

1. Can I reinstate the ACER now to manufacturer's condition?

2. How do i go about reinstalling XP?

3. please Note that I installed Ubuntu 11.04 (using) Wubi in Windows, & the netbook dual boots in Ubuntu OK, but not XP

 

Luckily on the last reboot I noticed a linux menu with 4-5 option, & one was "Acer eRecovery Management" which did the XP installation all on its own giving the option to save & install all files & programs.

Then, I went & installed Ubuntu 11.04 from my USB stick but, & now on boot-up it does not give the XP boot.ini Menu but, the "GNU GRUB" menu with 11 choices for Ubuntu (default) or XP, which is very complicated.

The rub now is how do I change the default to XP?

Any easy way?

by These:-
You can change the default menu
entry to boot by either going to the

/boot/grub/grub.cfg file and near the top of the file changing the entry: set

default="0" to another number. Count the menuentry lines until you get to xp.

Put that number in the set default. Grub counts in this case from zero, so if

your xp is the 5tn entry, put a 4 there.

To keep grub with default boot set to XP, you may use the GRUB_DEFAULT option
on /etc/default/grub (as already said by yancek) or change the
/etc/grub.d/30_os-prober file order.

Then :-
sudo gedit /etc/default/grub ......This brings up grub in editor & change to what ever No. you require.

sudo update-grub ..........this in a new terminal updates Grub.
