For some reason Grub (I'm assuming) won't boot OSX right.

turn off machine
reboot holding 'Option' key
Choose OSX

your are my hero....

anyway i can get rid of ubuntu?

Disk Utility in OSX - Erase that disk and delete partition. Drag your OSX one back over it.

didn't work..

what disks does it list? You may have to unmount them. It took some fumbling on my part to get mine back to full OSX.

Bootcamp
diskos7
diskos5


tryed unmounting and eraseing and nothing...

When you select diskos7, is it black or grey? select it and go to the Erase tab and try to format it as Mac OS Journaled then once it's done, click on the main drive and under the Partition tab, minus the space for diskos7.

no luck it says its deteleing them and they still show up

post screenshots of your Disk Utility using Grab (⌘ +Shift + 4)
