    Hello Macrumors!

    I am loosing my patience. IN the previous post i tried dual booting os9 from the universal disk and that failed.

    So! I tried os 9.2 from an imac retail restore cd installed os 9 booted into it, then installed 10.4 and now i can no longer boot into the os 9 partition! i made one partition when installing os 9 then the second when installing tiger. What am i doing wrong?!

    I'll try doing it myself. However, I'll be using 10.5.8 and doing a dual boot since I don't have a disk for 10.4.11 or any 10.4 version.

    I now checked the Os 9 partition and it has nothing in iT!!!! ARG. i did this a while back when i set up my os9 and 10.2.8 setup. I install os9 in one partition reboot setup second partition with os9 drivers and install it. after the tiger install the os 9 has nothing in it so im installing it again.

    Alright, I was going to boot off the disk, but for some reason this disk won't work. It shows up in OS x, but won't let me boot off of it

    I do this all the time.

    There's no reason why you even have to have separate partitions. OS 9 and OS X can be installed on the same partition.

    Boot off the Tiger disk and use Disk Utility from the installer to initialize the HDD as with however many partitions you want at the size you want, set them as APM(should do this by default) and install the OS 9 drivers.

    Then, boot off the OS 9 disk, and run the OS 9 installer. As I said, you can put either on a separate partition or on the same partition. If you use the same partition, use "startup disk" to select which one you're going to boot.

    Try doing it exactly as per instructions from bunnspecial - there's no reason why this shouldn't work, unless there's a problem with either the install disk, optical drive or hard drive.

    Well i installed Os9 on one partition, then installed osx on the second which for some reason didnt erase the os9 partition but it erased its contents. I simply then just installed os9 back on the other partition. it works now. Thanks

    Don't think that I think you are stupid, but just in case you maybe overlooked it or so. DId you perhaps choose the wrong partition upon your first try?

    An additional note for future readers: This is for iMacs with a DVD/CD slot in drive. For the iMac G3 with tray loading Drive there was something about an 8GB partition where either OS X or OS 9 had to be in. I don't remember right now....
    Also when installing OS X the first time you need to install the latest firmware under OS 9 first http://docs.info.apple.com/article.html?artnum=86117 and then install OS X.

    As far as I know, the most common problem is formatting a drive before installing OS9 (or OS X) and forgetting to check "Install OS 9 disk drivers." (like bunnspecial said)
    Does that fit your situation?

    No, I meant, for tray loaders and slot loaders there is a different procedure.

    For slot-in-iMacs (like the DV):
    1. - just format drive with OS 9 drivers via disk utility on your install disk
    2. - install OS 9.2.2 and update the firmware (if you not already had done so anyway)
    3. - then partition what you like and install OS X and OS 9 where you like

    For tray load iMacs (those with the uneven MHz numbers: 233, 266, 333MHz):
    1. same
    2. same
    3. partition not more than 8GB (something like 7,7GB) and the
    4. MY QUESTION: is the 8GB partition needed for OS 9 or OS X in order to work? The reason is an ATA restriction behind it. The files essential to the system to work have to be in the first 8GB.

    I don't have a (working) tray loader but have dealt with several OWR macs with the same restriction. As far as I know, it's only for OS x.

    I didnt have the OSX partition even partitioned. So when i was in tiger i didnt touch the os9 partition created tigers partition selected os9 drivers and began the install. nonetheless i just reinstalled os9 back on the first partition.
