I just updated to 10.5.8 and ran DellEFI with remove custom dsdt.aml, reinstall Dell Mini 9 extensions, restore 10.5.5 keyboard pref pane, and fix bluetooth checked after restarting the computer boots to the grey screen with the apple and spinning gear the shuts down.
I tried to boot to safe mode but it does the same thing.
Just tried to restore from an older backup and it failed after restarting the computer it just goes to a black screen and has
Boot0: GPT
Boot0: testing
Boot0: testing
Boot0: error
and then i have to turn it off, it just keeps doing it. I have even tried to boot to the restore disk that came with the computer and it still does it.
Anyone have any ideas?
