Problem: Using rEFIt so I can dual boot between Mac OSx and Windows 7. Every once and a while, the menu to choose what operating system to use disappears. For what seems to be no reason..
Solution: According to rEFItâ€™s website, running OSx updates might disable rFIt but it doesnâ€™t do it all the timeâ€¦ Run the following commands within your Mac OS and the menu will come back.
- Open Terminal
- type cd /efi/refit
- type ./enable.sh
- you will then need to put in the administrator password and youâ€™re golden.
