I have a 21.5" iMac (Intel based), and I recently installed Ubuntu on a 90GB partition. After I installed Ubuntu, I noticed that whenever i boot my machine I get GRUB where I can select my OS (Mac or Ubuntu). GRUB came after I installed Ubuntu and it is using the Ubuntu color scheme, so I know it relates to Ubuntu.
Problem is, that when I am in GRUB my apple wireless keyboard is not working, and after 10 seconds Ubuntu gets auto-selected, and I can not boot into Mac OS X without a USB keyboard.
So I wondered if it is possible to solve this problem, and if not - how can i replace GRUB to a mac boot menu or maybe to rEFIt? Thanks for any help!
