It’s been twice my OS boot selection been removed after installing Crunchbang Linux (based on Debian Squeeze). After search on Google, I found this link (although it was meant for ubuntu, but it works fine on me)
Maybe that tutorial a little bit hard to novice user. I found another simple way to do this.
- Run your favorite console & Install OS Prober program by typing this:
sudo apt-get install os-prober
- running it using console
- Update your grub by run this command
Reboot and it should fix your OS boot selection menu.
PS: if you run sudo command, you’ll be promt to enter your administrator password.
