Do you have to have OS X already installed before you can run the OS X 10.1 Upgrade CD? Or can you run it directly from OS 9.1?

You have to have OS X installed. p

You can install the full OS x from that upgrade CD; 1.Insert your MacOS X 10.1 Update CD 2.Fire up "Disk Copy" from /Applications/Utilities 3.Select from the Menubar "Image | New Image from Device..." 4.Select your CD-ROM drive's contents from the resulting dialog 5.Image it as a "DVD/CD Master" type (this will take a little while) Modifying the CD contents 1.Control-click (or right-click) on the resulting disk image 2.See that it's mounted 3.Navigate with the Finder to System/Installation/Packages on mounted image 4.Select the "Essentials.pkg" file... 5....by right-clicking on it and select "Show Package Contents" 6.In the pop-up Finder window, navigate to Contents/Resources/ 7.Drag "CheckForOSX" to the Trash and close all these Finder windows Burning your new Install CD 1.Go back to Disk Copy and select from the Menubar "Image | New Image from Device..." 2.Select the mounted volume you opened up above and make another "DVD/CD Master" image 3.Now select from the Menubar "Image | Burn Image..." 4.Select your newly modified .dmg file 5.Burn it to CD and enjoy

The checkosx file has been removed but still when I try to install, there is no harddrive viewable to install OS X. I currently have os 9.1 installed. Please help.

What Mac? What size hard disk? Is there enough room on the hard disk to install OS X? If it's a beige G3, original iMac, or pre-Pismo PowerBook, are you trying to install on a partition that is entirely within the first 8GB of the hard disk? p

It is a Powermac 233mhz G3 Beige minitower with 288mb ram. It has a 4.2gb drive. The drive is not partitioned. When system boots with os x cd there is a disk utility that is available for use but I can't get no where with it. Any help would be appreciated.

Bob, does the aforementioned process of using the OS X Upgrade CD work from OS 8.6 as well? Thanks!
