iMac G3 350MHz slot-loading hanging on Apple logo after installing OSX 10.3

After installing Mac OS X 10.3 onto my iMac G3 (350MHz, indigo, slotloading), on booting I get the normal boot chime, brief hard disk activity, the Apple logo, a little more hard disk activity, and then... nothing. The Apple logo just stays there as the hard disk whirs away without any audible activity. (chose eMac as the device option here because there's no option for the iMac G3)

A prohibitory symbol, which looks like a circle with a line or slash through it, means that the selected startup disk contains a Mac operating system, but it's not a version or build of macOS that your Mac can use

Try to boot the machine using the installation media. Is it works?

Hi,


First of all, I guess that it would be correct to assume that the appropriate firmware update had been installed earlier.

iMac Firmware Update 4.1.9: Information and Download


Is it a retail Mac OS X Panther 10.3 disc (not a model-specific version for another Mac)?


How much RAM is installed (the Mac OS X 10.3 minimum requirements were 128 MB)?


Any information about the hard drive size, formatting, and free disk space?


Also, the answers by Allan Jones in an old discussion (albeit for Jaguar) could perhaps be of interest to you:
