Hi John French!

Apparently you are able to boot live?

I have had problems with certian hard disk drives.  The last time I
had something like that happen it went away when I reformatted the
disk using the Ultimate Boot CD utilities for the disk.  It needed a
fairly low level format.

Other than that, you may need to use the alternate CD and turn off ACPI.

My two thoughts.

Good Hunting!


Ok, you should also Google "ACPI : Unable to locate RSDP" or portions thereof.
