How to boot windows automatically? [duplicate]

I recently installed ubuntu (dual boot with windows).

I want to boot windows automatically unless I manually choose ubuntu.

I use grub and startupmanager (yes I know obsolete). I am running ubuntu 14.04 and windows 7.

Can someone tell the procedure to do this?

Solution 1:

• Press Ctrl+Alt+T, type gksudo gedit /etc/default/grub press Enter and enter your password.

• You will see the following contents:

  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=""
  

• You can change the default from 0 to any number, corresponding to the entry in the Grub bootup menu (first entry is 0, second is 1, etc.)

• Then run sudo update-grub

Important: To get grub file in /etc/default/grub if not exist, run this command:

sudo apt-get install grub2 grub-pc

Then run

sudo update-grub

Solution 2:

Use a program called grub-customizer to modify your grub files - this will allow you to select the windows installation as the default boot.
