Troubleshooting Software Related Issues
The C: partition contains the operating system and the instrument application
software, so boot problems can be caused by either a failure of the operating
system or the instrument application software. The failure could have occurred
due to a failed installation procedure, instrument application software update
failure, a virus, etc...
To correct these issues there are two procedures that can be initiated to resolve
a software related issue.
— Reload the instrument application software.
— Use the Disk Drive Recovery Process to reinstall the operating system and
instrument application software to the state it was in when the instrument
left the factory.
Reloading the Instrument Application Software
The instrument application software contains all the required components for
the instrument application as well as all software options. If the instrument
application software has become corrupt the operating system will boot but
the instrument application software will fail to start. In these cases go to
Chapter 18, “Instrument Software.” for information on how to update the
instrument application software. This procedure will not affect the instrument's
calibration or user files.
If this does not resolve the boot issue, or the instrument never boots the
operating system proceed to the “Disk Drive Recovery Process”.
