Installed Ubuntu 9.10 on macbook pro but won't boot properly

[Olnex]

I installed Ubuntu 9.10 desktop x86 on my macbook pro, I selected erase and use entire harddisk, after install, I restarted, but there is only a flashing question mark on a gray background screen, if I press option when power on, I can select a disk called "windows", then it boots into ubuntu, I wonder what is the problem?

Thanks a lot!

Olnex,

Maybe the guys in the apple users sub-forum (http://ubuntuforums.org/forumdisplay.php?f=328) can help.

Have you updated GRUB2? Here's a link from DRS30 (http://ubuntuforums.org/showpost.php?p=7505203&postcount=1)5
