This has probably been addressed numerous times, I've done various forum searches to arrive to where I am now. Attempting to Boot from USB via firmware, i've attached an image of how far I get until it reads 'LOAD-SIZE too small', and I'm wondering what this means? Is the USB memory too small to boot from? 4gb holding a condensed 2.7 dvd.toast of OS x 4.11. Instructions I've read from other ibook g4 14' owners state that the last instruction should automatically force a boot from USB, yet I am stuck. When the usb is inserted and 'C' is held during boot the USB drive flashes 3 times, so i assume the system is searching for a os to run? But it does not show (again, image attached, only HD X is present and refresh and boot button. When I insert the usb drive into my Emac, i open the file itself, and then go to Startup Disk in System Preferences, it says it is available to boot from?? (Again, image attached). The disk is (2), partition is (10) if this is helpful ( i did reference these during attempts in firmware but got nowhere). thanks Any ideas or suggestions please and thankyou in advance.
