If i have to delete Mac OS 9 before what do I use to put Mac 10.4 on then?

Answer 1

Don't try to remove OS 9 first, use the OS 10.4 disk. Put the disk into your computer and start the installer. This will reboot your machine from the disk. Once there you'll be given a set of install options. The best one (if you have room on your drives) is an archive install (this puts all previous system folders into an archive folder, rendering them un operational yet you can still retreive anything you might want.) Clean install will reformat your hard drive first and delete everything on it. Importantly, check your machine spec. If you are running OS 9 then you'll not be on an intel based mac so there may be an upper limit to the level of system you can use. Theres a full compatibility list on the apple site but if I remember correctly, anything after the G4 mirror door should be ok.

Answer 2

Who told you to delete OS 9? You don't need to delete anything as long as you have at least 3 GB of free drive space so if you have that much, install OS 10.4. For that matter, if you have enough partitions and they are formatted correctly, you can have OS 8.6, OS 9.1, OS 10.2, OS 10.4, YellowDog Linux and BE OS all installed on the same PPC MAC. Choosing from among all of them at startup is another kettle of fish. Here are the requirements given by Apple for OS 10.4:

* Macintosh computer with a PowerPC G3, G4 or G5 processor
* Built-in FireWire
* DVD drive for installation (unless you have the CD set)
* 256MB of RAM
* 3GB of available hard disk space (4GB if you install the developer tools)

Archive and Install will not affect the OS 9 System Folder. It will still be there and ready for use. You can only use Archive and Install if you already have installed OS X so it will not be an option at the first install of OS X. The Archive and Install option is intended to save a previous OS X installed system (the folders named "System", Library", Applications" and, if you choose to save users, "Users") so it doesn't care about OS 9 which uses folders named "System Folder" and "Applications (Mac OS 9)".

If your OS 9 system is version 9.0.x and you boot to OS 9 after installing OS 10.4, you may not see the option to select OS 10.4 in the Startup Disk Control Panel of OS 9. To solve this, either launch Classic while booted to 10.4 which will install an update of the Startup Disk Control Panel in OS 9 or put the OS X CD in the drive, but just open the Utilities folder on that CD and you'll see a Startup Disk 9.2.1 item. Drag that out of the CD window and drop it onto the "System Folder" (not the "System"). You'll get a message that it needs to go into Control Panels, click OK. You'll get another message "already exists, do you want to replace it?", click yes. Now when you open the Startup Disk Control Panel, it will show the 10.4 option.

Answer 3

Don't try deleting OS9, your computer is sometimes in need of the backwards OS.
