iMac boot problems
Hi,
I have a iMac(iMac9,1) here which experiences some boot problems. If you try to boot "normally" it just sais "No bootable device". Keycode's don't work so I imagened that the firmware password was active. And indeed; holding the option key gets me to a password an after that a screen where I can choose where to boot from.
If I start from the harddisk, most of the time Mac OS X starts. But it takes a very long time and the performance after starting isn't that great either. I repaired the harddisk using the disk utility on the Mac OS X DVD and tried to delete the firmware password(so I could try to reset the NVRAM at startup). But it just doesn't reset, althought it should(I even couldn't change the password while starting from the DVD). That seemed very odd.
By the way; using the startup disk utility gets me nowhere either.
Also if I reinstalled Mac OS X, it would do fine until the very end, where I got an error. The installation works but with the same boot problems.
Since the "no bootable device"-problem seems to be a Windows problem, I tried to recreate a windows partition so I could after that delete it again. But opening the bootcamp assistent just gives me an error saying that I need to update my ROM-software, which I can't update because it has the newest version already.
Is there any way to just reset the EFI?(there is no firmware restoration disk for this mac)
I hope someone can help!
Regards,
Dennis
