Hi, recently i wanted to upgrade my iMac 24`, os x ´to 10.5.7. At the very end I`v got the empty screen (light blue) with only the pointer for a rather long time. I tried with manual restart and got the message: Debugger cancelled (panic) .... Kernel trap at 0x00000000, type 14 = page... error code 0x000000010. It asks to restart the comp and after the restart the same message comes again. I tried with inserting the original os x DVD (iv got with the imac) but it wont start the reinstallation. ´ I disconnected the power cord for 2 min. still nothing. Basically, i can not do a thing. Is there any possibility to reinstall the os x from the beginning.
