I had a messed up windows install disk one time stuck in my drive and it caused this, try holding eject from power up, this may force the disk to eject. also if u can get to the firmware there is an eject command that force ejects disks.

Your computer cannot find a valid startup folder. Either your system is corrupt or your hard drive has failed. Try starting up from your original system installation disk by inserting the disk and restarting holding down the "C" key. Go to the second screen pull down menu to Utilities > Disk Utilities. See if your drive shows up in the left hand column. If so click on it and see if you can repair it. If not the hard drive will need to be replaced. Let us know your results and we can proceed. I also can't tell if you have an iMac or MacBook. Please give us the last three figures of your serial number so we are both on the same page.

okay i'll try that Mr. Mayer.

its an IMac(Intel) model A1207 i have to search for the original system installation disk , i own a macbook too. insert the disk number 1 into the iMac drives and hold "C" while starting but nothing happens . i'll go now and try again. if nothing happens i'll have to search for the iMac original system disk.

i'll brief you back as soon as something new comes up.

thank you Mr. Mayer

I have the M A1207 model too...my died like this a year 2 years ago. Every once and a while I'll try turning it on following all the ideotic suggestions like hold down shift, hold down space bar, hold down letter d on start up ... noting works. What a joke. My computer came pre-set up so there is no disks to try...nothing.

Fustrated as it died after the 3 year warranty had expired. What a waste of $1500 for a better product
