I managed to screw up one of my machines last night with font problems -
so I ran Time Machine overnight to do a complete system restore. It all
seemed to work - but it won't boot - just get the Apple symbol and the
spinning cog at startup. I don't really want to do a a piecemeal restore
of the system as it will take ages - any ideas how to make it boot? The
info is:

� Mid-2009 Mac Mini with self-upgraded disk and memory
� Disk is in two partitions - restore done to one partition
� System restored is latest Snow leopard, from Time Machine backup on a
USB drive
� Installer DVD says system is bootable and shows it as a startup disk
� Running Disk Util and repair does give a final message 'Updating boot
support partitions for the volume as required' - and reports the disk OK
otherwise.

Is that last point a big clue - it doesn't fix it.

A better clue might be in the details of how/why it doesn't boot. Try a
verbose boot, or a single-user boot.

I've just reset the PRAM and that now gives the startup chime (which wasn't on before). But still not booting.

Single-user boot shows:

'can't load kext com.apple.driver.AppleFW0HCI - not found and kextd not available in early boot'

Also 'Root device is mounted read-only'

can't see any other info that looks wrong - there's a long string that begins 'Got boot device = etc'

I would try DiskWarrior followed by - if that failed - the last combo
update.

That's probably OHCI, not 0HCI. Have you got anything attached to the FW port?

That's what happens during single-user boot. It tells you what to do to
continue IIRC.

Anything else from a verbose boot?
