My mini 9 will no longer boot after 2 years for flawless service. I put the disk in another identical mini and it won't boot there either. I can boot into ubuntu from a usb disk and I an see my disk and disk utility says the disk is fine.
I no longer have any of the original instal media.
It won't boot into single mode either. When I boot -v i see the complaint about a checksum cookie not valid.
It then shuts down.
It was running 10.5.8, has a 32GB runcore SSD
, and has the A04 bios. Chameleon v1.0.12.
Any ideas of how to fix this without my install media is greatly appreciated. If I can't get it back I will have to install linux.
