    How to avoid long EFI wait before GRUB without Mac OS X install disc?

    I have successfully installed Ubuntu 10.04.3 Server LTS on my Apple MacPro. Everything seems to be working just fine, except one tiny problem - it boots too slowly.

    https://help.ubuntu.com/community/Ma...elInstallation says:

    Avoid long EFI wait before GRUB
    If your Macbook spends 30 seconds with "white screen" before GRUB shows, try booting from your Mac OS X install disc, select language, then click Utilities->Terminal, and enter:

    bless --device /dev/disk0s1 --setBoot --legacy

    Assuming that the bootloader is on sda1, otherwise /dev/disk0s2 if it's on sda2, etc.

    But the problem in my case is that I do not have Mac OS X install disc. I wonder is there any other way to avoid this long EFI wait before GRUB?

    Do you still have OS X installed on a partition?
