Need help changing boot order ~ Zorin ver 8 installed on iMac

chriscareaga

I have searched a lot of places and have been unable to find an answer to this.

I have Zorin ver 8 installed on an iMac. I want to install Zorin 9 and I have it on a CD as well as a USB thumb drive (bootable) My problem is getting the iMac to boot to either the CD or the thumb drive.

I have tried to get into the MAC BIOS by holding down the Windows key, Alt, O & F keys (I don't have a MAC keyboard) but it does not work.

Any ideas/ help would be greatly appreciated.

Thanks in advance!

Thanks for your quick response. However, I had read that by doing a Google search and it just causes the machine to hang.....more than 5 minutes worth.
Thx anyway.

What model Mac have you got? Is it a PPC or an Intel? Have you burnt the correct disk?

It's an iMac 24", Intel. I burned the ISO that I downloaded from http://zorin-os.com/free.html using Ultra ISO. The disk, as well as the usb boot on my win 7 just fine.
