Re: ? imac g4 ? problem starting
This looks to be a hard drive issue....if you are familiar with the machine enough to take off the bottom plate.....requires a torx tool. I would take off the bottom plate and disconnect the hd, and then see if the machine will boot to cd...if it will then boot to cd then it is a hard drive... i would be careful though as there is a pad on the processor that cools it and if it becomes dislodged you can overheat the processor....

It can not find the hard drive or the startup folder on the hard drive. Try and fix that by putting in the original boot cd/dvd and repair and choose your hard drive start up folde as boot device. If you can not your hard drive may have died.
First hold down the right hand shift key down when you start, this does some housekeeping, The next step is if you have an install disk or tiger disk then start up from it by holding the "C" key down when starting and inserting the dvd, if this loads then go through the install menu, dont worry you do not need to actualy install just select language and then you get to a screen where you can select utilities from the menu bar, then select disk utility and repair permissions, after that do a repair disk then quit disk utility and change the startup disk back to the hard drive and restart, if for some reason you cannot repair the disk, this refers to the catalogs it uses to keep track , not the data itaelf, in that case you need a 3rd party utility like Disk warrior.
Try reinstalling MacOS on your laptop, as far as I know, all Mac come with recovery disks. To boot of off a disk, make sure the disk is in the drive , reboot the computer, and press C while the chime is playing. You SHOULD be able to reinstall. What your describing usually happens to very old iMacs that have bad, incompatible, or no RAM installed. If none of the above works, take it to an Apple Store, they were very helpful when my iPod had a bad battery
Some of the start up files have been corrupted or are missing. Start up from the OSX system disc and them run Disc Utilities from the installer toolbar. Check the hard drive for errors. Repair any errors if they are found. If it's not possible for Disc First Aid to repair the hard drive you will need to replace the drive and re-install OSX.
You have mentioned that you are looking at replacing the hard drive with a SATA one. Since the G4 iMacs use PATA hard drives (an older standard) you will have to make sure that the drive you use is a PATA.
Aside from that, you should be able to upgrade to a reasonably large hard drive up to 500GB and then format the drive for a mac.
The only real trouble you will have in my opinion will be the installation as the process for taking apart a G4 iMac is very advanced. There are a few guides on how to do this, just make sure that your skill level is advanced enough to attempt the upgrade. Also, of course, make sure you have backed up all of your data and everything before you start... that can mean a world of difference to you later on if anything goes wrong.
I would personally take a trip to the Apple store and talk to a genius about this sort of upgrade, or look at other upgrade options such as a bigger external hard drive because there are many complications in this upgrade and those two options are easier.
If you are interested in attempting the upgrade yourself you can look at this explanation of the process, it is quite thorough and has pictures showing internals and the process. http://www.xlr8yourmac.com/systems/imac_g4/imacg4_takeapart.html
If at the end of that you want to go ahead and open your box up by all means do and I will be here to offer as much support as I can.
Well the flashing question mark means its not finding a bootable device meaning the hard drive has no OS on it. You should be able to put jaguar on it if its a retail version and not one from another mac product. Let me know how this works for you
it won't read it because the new os disk is double layered and the g4 drive you have probably won't read double layered dvds. best solution is to buy or borrow an usb external dvd drive. i did this last week and it worked fine.
It;'s not a great Idea flipping the mac over they have a special stand to put them on when working on them. But it should be able to cope with it. Your mac is relatively old now. With all the moving around it could have just given up the ghost.
They are quite tricky to work on with the hard drive sitting on top and the cables running over and down the side there is a stack of heat generated there. Just make sure you put ll the thermal back in. If it's not a miss seated connection it could be a number of things. Cable, heads. Trouble shooting is quite tricky. As it is a desktop, in a lot of cases it is cheaper to buy an external DVD reader/writer. They are faster now!
You should be able to install OK when it is in terminal mode. You could run disk utility but more than likely you'll have to run the installation again.
sounds like hd is getting hot via firewire try and use the usb lead if same problem then get your files off quick and repace drive any thing above 80 gig will get hot in use that's why I use harddrive coolers on my large 300gig 400gig internal and only use my 250 gigs and 160 gig only when i need the files off they are turned off all time
