Hello everyone: This is my very first post in this forum so please bare with me. So i have a iMac G5, and every time i boot up the machine i get blank gray screen for about 3 minutes and after that, a small icon of a folder with a question mark. I downloaded Mac OSX Leopard to preform a clean OS install, then i burned it to a DL-DVD as an image (.iso) and finally, tried booting the iMac using the "C" key but it only reads the disc, ejects it and goes to the same screen with small folder icon. What i did next was, took out the hard drive and plug it into my macbook (via USB) and erase all the content using disk utility. At that point, my macbook recognize the hard drive so i thought that i would work if i put it back into the iMac. However, i keep getting this black gray screen and a folder with questions mark right after. I'm not really sure what to do next, should i replace the hard drive? or should i format the hard drive to an specific file system? Please advice Thanks a lot.
