G’Day,
I thought I’d be brave and just go ahead and install CentOS 5.4 linux on my macbook pro (late 2009 edition). Part of the thinking was that if I have problems, I’ll get to learn more about the macbook. I backed up my drive, and I plan to replace the drive with an SSD anyway, so I was feeling pretty fearless.
After a few tiny hiccups, It was installed (I decided not to install grub figuring it might mess with the boot loader (and I had already installed refit). But reboot .. nothing .. just a dreaded error
I tried a few keys to see if I could get any kind of bios settings. Nadda. So a little googling, and holding down the “option” key when booting gave me a nice looking icon with Macintosh HD, so clicked on that, and bingo. Back in mac land. And then the mac continued to reboot just fine after that.
I imagine other people might have the same problems when installing Windows XP, vista or windows 7. I also imagine that I did something not quite right.
