Q: iMac shuts down on start up

Feb 1, 2013 7:01 AMby Shorteared,Hi thanks for that, however I may have run into another problem. It seems that my wireless keyboard is connected to my iPad not my computer. When I try to load the Startup disk and hold down C the same thing happens ( computer shuts down).
Is there a way to connect the keyboard during startup? I believe this is my issue.

Feb 3, 2013 6:09 PMby Shorteared,Hi Linc, I had to go buy new keyboard with a cord to attempt anything. What I tried was pressing Option, Apple, P, R at start up which got me to the disk utility. From their it asked if I wanted to repair a disk ( amongst other options). I attempted to repair the disk and it stated in RED:
Error: Dusk Utility can't repair this disk....disk, and restore your backed -up files.
I am worried anything I do will erase all of my files. Do you know what I should do next to prevent the loss of my files?

1. Boot into Recovery (command-R at startup) or from a local Time Machine backup volume (option key at startup.) Launch Disk Utility and follow the instructions in the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”
How to back up and restore your files
2. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire or Thunderbolt cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.

3. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.

Feb 11, 2013 3:32 PMby Shorteared,Hello again,
I have finally purchased the external drive and fire wire and have followed Lincs instruction (however just held T at start up). When I do this the fried hard drive shows the FireWire symbol but the other Mac shows a warning:
You have inserted a disk containing no volumes that Mac OS X can read. To continue with the disk inserted, click ignore.
It does not show up in the finder. If I run disk utility it shows up as 465.8 GB AAPL FIREWIRE Target media. I have tried to create a new image when I select this disk but when I do a warning comes up:
Image/device is too large
And does not create the image on the external hard drive.
The working computer is one of the old bubble computers running running Mac OS X Version 10.3.9, processor 400MHz and 192 MB SDRAM. The broken drive is new running 10.6.2.
Do you think the bubble computer is just too old? I need help.....what is my next move...anyone?
