[SOLVED] changing default OS

I installed Zorin alongside with Windows 7 and I would like to change the default OS to windows

One easy way would be to install the startup-manager and change it from there.
To install open up a terminal and write:

Code:

sudo apt-get install startupmanager

If this will not work (there have been some roumors that the startup manager is not working for everyone) try the following:

When you boot and the grub menu opens, count the options in the grub menu and remember which number is the win7 option. (i.e. lets say for example that the win7 option is the last one in the list - i.e. the 6th one - counting from up to down).

When you log in to your desktop open a terminal and write

Code:

gksudo nautilus

Navigate to /boot/grub/ and open the file "grub.cfg".

The file starts something like this:

Code:

GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10

Change from the 1st line (GRUB_DEFAULT=0) the "0" to the number of the grub option that you want to load automatically at start-up.
NOTE: "0" is the number of the first option (i.e. now is linux). So "0" is for the 1st option, "1" is for the second option etc. Thus, if the Win7 option was the 6th one in the grub menu, you should insert number "5" in the line above. Is this understandable?

Once you change the first line i.e. to: GRUB_MENU=5, save the file and exit.

Open terminal again and write:

Code:

sudo update-grub

Reboot and hopefully this time the load option would be win7.

Thank you very much for your help.
