Im trying to dual boot between mac 10.6.8 and ubuntu 11.10. I have a macbook pro 8,1.
So i installed from a 10.04 disk because the install window makes more sense to me, and it doesnt give me errors or anything. Also, any versions of ubuntu after that dont boot from disk for whatever reason. (i think its having to do with the efi boot thing. i have to get ubuntu 11.10 to boot from a usb with folders boot>efi>boot.iso) Then my plan after that was after the ubuntu 10.04 install took care of all the swap and stuff for me without being messy, to upgrade to 11.10.
So here i have 10.04 booting successfully back and forth from mac osx no problem. I put in my 11.10 usb and the installer gives me the option to "update 10.04 to 11.10" bingo, jackpot, thats what i want.
Everything proceeds as normal, as EVERY OTHER install of ubuntu i have ever done, then the installer finishes and says HEY! im finished! Continue testing or reboot now!
So i reboot, and what do i get??? A black screen that says the file system isnt found, to enter a boot disk and press any key.
so i boot the 11.10 installer again from usb, and select "erase 11.10 and install 11.10", installer proceeds normally, and asks me to reboot.
I reboot and get the SAME THING.
Please, someone, help me get this right here. This is my first time actually dual booting between mac and linux. Usually i just wipe off osx completely and install ubuntu but i actually need to keep my mac partition this time. I have successfully installed 11.10 on this machine before, but that was when i did a clean install.
