Insert the system CD, restart the computer holding down the C key until it boots using the CD. Then run through the initial screens as though you are going to reload the system software until you are given a menu bar. Select Disk Utility from the menu bar when you can and then you can run disk first aid and 'Repair disk'. ![]() If this works OK then you are back up and running after a restart. Otherwise you will have to reload the system. Note: when you have booted of the CD, you should be able to access the hard disk and retrieve any files you want first to an external disk or memory stick before reinstalling the system software. Good luck - TT Posted on Dec 13, 2008. Teraterm macros. Check all cable connections/power connections to the CD drive. You should be able to boot the G4 with the CD in the drive and holding down the 'C' on the keyboard, as has already been said. It should make no difference what brand of USB keyboard you use, just be aware that there may be some key mapping differences: such as the CMD key on a Mac keyboard will be the Windows key on a windows keyboard. I am currently using a Dell USB keyboard w/ my G4, whatever is handy with my Macbook, and a Compaq keyboard with my G3. Have you tried zapping the PRAM, it shouldn't help an issue like this, but is worth a try. Restart your computer and hold down the CMD-OPTION-P-R keys during startup, wait until you have heard 3 chimes then release the keys and let the machine boot. Also, What are you using to boot the G4 with? Since certain mac install disks will run on certain hardware. For example, you cannot go any get Mac OS X SL (10.6) and expect it to work. Neither will 10.5 (L). The last OS X release that will run on G4 Machines that is 100% is Tiger. (10.4) But getting a OE copy or Retail copy of tiger now a days can be difficult. And it may take a few tries to get it to install on the machine. (It took my G4 3 tries before the install finally took). Another thing, what G4 style is it? Since there are many different sub-models. Each one has different hardware specs, Some may run 10.5 others wont. Hardware is key with Mac OS's. Booting your iBook G4 from a USB stick So I spent the better half of the night trying to figure out how to make my iBook G4 boot from a USB stick. I have the Leopard ISO, but none of my DVD drives will burn Dual Layer, so I needed to use the USB route. IBook G4 1,42 Ghz with USB Stick: ) Reply Delete. (Unless your installing Mac OS 9.2 on it) Is it a burnt cd/dvd? Because Macs in general do not like booting on burnt disks and require the 'special' boot sector to boot on. What happens if you leave the machine on for about 5 mins does it load the cd? The reason why I ask is with my G4 with a transplanted HD out of a normal pc (formatted as NTFS) it wouldn't load the cd using the shortcuts on the keyboard. ![]() And it finally boot the dvd for me. Usually clearing the PRAM will only help with non-boot / start issues where the machine won't turn on. Coming in on this late, and I apologize if it's already been solved. I haven't seen any indication that the machine is starting and loading firmware correctly. Do you hear a 'chord' as the startup chime? (In particular, NOT a series of beeps or 'bird chirps', which among other things is the way the Mac tells you it has a bad memory chip). There 'should' be a functional internal speaker if you unplug any external speakers -- but just in case, you might want to have a known-good set of speakers to plug into the back. I have never had difficulty using a USB keyboard to get my G4 towers to boot from CD by holding the 'C' key (but nothing else!) down immediately after you hear the chime. This does presume: 1) that your CD drive is connected and workable; and 2) that the CD is actually inserted in the drive when the system goes through power-up.
