I have an old iMac G3 that had OS9 and Tiger (10.4.11) on it. I had to repartition the HD and in removing the second partition and expanding the first to take up the whole drive, I lost the "blessed" OS9.2.2. The iMac still runs classic, but if you go to the Startup Disk preferences, OS 9 on that disk is shown and if you choose it, it stall because it can't find a startup disk and worse, if you restart it with the options key, OSX bootup option is no longer shown. To remedy this problem I want to either reinstall OS9 without partitioning or reformatting the HD, or if this isn't possible, to set it in a way so that Classic still works but the option to boot from OS9 no longer shows from Startup Disk. (I will be selling this Mac and I don't want an inexperienced user to run into the same problem I did.) I actually have an OS9 install disk (9.2.1) - can I just reinstall OS9 onto my HD with this disk in a way that doesn't remove OSX?
