Change Your Default Boot Selection

After messing around with kernel 3.2, trying to get my machine running on:

yuvi@yuvi:/boot/.bak$ uname -a

Linux yuvi 2.6.35-32-generic #64-Ubuntu SMP Tue Jan 3 00:47:07 UTC 2012 x86_64 GNU/Linux

to recognize beceem wimax chipset with no luck, well, at least until now, my boot list is now like a scrambled eggs, see this boot.cfg below, count how many entries i've get, now im desperately trying to get rid of it. I've tried moving all the images in /boot and run grub-mkconfig afterwards ... doesnt work.

It took me a while to notice just this line:

set default="0"

in grub.cfg and change it to 2 and by default, it goes directly to my third entries as default.

I know there is much cleaner way to update default entry for boot, but ... to be honest playing around with this is much more fun ;)
