 Can you please boot into sysinst, then use the Utilities menu to start
 a shell and show us the output of
 
    disklabel sd0
 
 ?
 
 I suppose the Tru64 installation left something on the disk that we
 misinterpret - and sysinst needs to validate and clean that.
 
 If you want a quick workaround: after copying the disklabel output for this
 ticket, do something like this to clear the start of your hard disk:
 
   dd if=/dev/zero of=/dev/rsd0c count=200
 
 and reboot. I guess sysinst will work then (but this may fail due to label
 sector write protection).
 
 Thanks,
 
 Martin
