hello, have been using ubuntu few months now, , has been hard learning things on own, code in windows, fun.

1 thing modify settings in gnu grub boot last used os, can me? tried read manual, lets it's big, big, , few instructions found related wanted turned out useless.

as far know there no option boot "last used" os. can show how edit grub configuration file on default os booted. important here how many grub entries have, default should normal dualboot:

code:

linux headers  linux headers (recovery)  memtest  memtest 86  /dev/sda windows

making total of 5 entries, starting @ 0. last entry, in example windows, have entry number 4. once booted ubuntu can open terminal , type

code:

gksu gedit /etc/default/grub

open configuration file. there edit line says

code:

grub_default=0

there change number entry number of os boot default (change 4 if want windows shown in example). can edit line

code:

grub_timeout=10

on how many seconds grub bootloader supposed "wait" input before loading default os.

after done changes, save settings.

type command in terminal

code:

sudo update-grub

changes take effect.

done
