Dual booting is somewhat of a problem, I would like windows xp for older games, which cant be played on win 7 or linux.

If someone could post up a guide, it would be good.

No problem, San Migs. Ideally you should install Windows first. I know you have a debian or ubuntu based preference from what you have said before- so once you have Windows inhabiting the whole hardrive, just boot up your ISO and install and go for the 'install alongside' option. When you get to the drop down options for where your grub-bootloader will be installed make sure you check it because it may be set on installing the bootloader on the sodding DVD -disc and if so then at some point installation will abort-and then you'll be in shit street. Make sure you choose the hard drive.

Now then-if you have Linux already it is a bit more complicated; and when you have installed Windows you will not be able to start Linux. If you really don't want to reinstall Linux-easy-peasy get back to me, but Linux is so easy to reinstall.

If you want to change the boot order-say you want Windows to start by default just follow this-

sudo gedit /etc/default/grub
You will got something like this :
GRUB_DEFAULT=0
#GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash”
GRUB_CMDLINE_LINUX=””
# Uncomment to disable graphical terminal (grub-pc only)
#GRUB_TERMINAL=console
# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo’
#GRUB_GFXMODE=640×480
# Uncomment if you don’t want GRUB to pass “root=UUID=xxx” parameter to Linux
#GRUB_DISABLE_LINUX_UUID=true
# Uncomment to disable generation of recovery mode menu entrys
#GRUB_DISABLE_LINUX_RECOVERY=”true”
Now to change the boot order, you need to change the GRUB_DEFAULT Entry, for example you have� windows7 in the 3rd position and you want to set it as default, to do that set default to 3:� GRUB_DEFAULT=3
2- Now update Grub using the command:
sudo update-grub
Oh yes- some distros will use 'pluma' instead of gedit-if that is the case, replace gedit with pluma.
