how are you booting to Ubuntu? Also how did you install ubuntu?

I have a MBP rev2 and installs fine with 8.04 X64 RC Alternative Install.

neway

in OSX download and install rEFIt. Its a boot manager. Reboot and dont hold alt or c or d or anything. Let rEFIt install, and choose Partitioning tool. It will run and ask to update the MBR
choose "y"

this will rewrite the drives MBR allowing grub to boot. Will also allow you to use fglrx or nv drivers and enable glx (glx requires BIOS functions and requires mbr to be enabled)

hope this helps

I have installed holding "c" no problem but rEFIt works nice too.

good question, but it sounds like an issue with refit since you never make it off the refit splash page.

thanks every one
i am writing now from ubuntu 8.04 rc
and every thing works fine except isight of course
the trick was
1- update mbr.
2- shutdown the computer.
3- turn it on and boot into mac osx.
4- restart and enjoy linux!!

To get iSight working in Hardy, you need iSight-Firmware-Tools:

I would restart completely just to be sure, but restarting hal should do it too. Also, make sure the firmware shows up in /lib/firmware/

I have similar problem with final 8.04 on Macbook 3,1
After rEFIt screen, cannot start Ubuntu. The message says "No bootable device -- insert boot disk and press any key"

I had no problem with Beta version. Some thing is really wrong. I followed the instruction. Applied Mac updates, EFI firmware update, even new eEFIt 0.11. But no success getting into Ubuntu even after several restart.


Any help... Thanks in advance...

Any help... Thanks in advance...you need to select the partitioning tool in refit to sync the partitions.

The reason is that the hybrid GPT/MBR partition table confuses ubuntu installer.
Gusty installer decides to use the GPT and leave the MBR table untouched.
But Hardy installer decides to erase the MBR table completely and turn the disk to GPT only. This is bad because grub still needs an MBR partition table. And if there are still other "legacy" OSes on the disk like XP, vista, they will also become unbootable.
I encountered this problem yesterday, I was quad-booting OS X/XP/vista/ubuntu, and after installing Hardy, i can only boot into OS X. i ran fdisk /dev/rdisk0 and found the MBR table was gone. I rebuilt the MBR table manually in terminal. ( i forgot that i can use the refit tool to sync tables) Then i can boot all the OSes but vista said it needs to be repaired.
