I have a WinXP machine that won't boot after installing the Lenovo ThinkVantage updates (which includes things like WIFI and video drivers).
Regular boot hangs just after the WinXP Splash Screen.
The machine fails to boot in Safe mode (mups.sys last line)
Complicating the matter is the machine has PointSec full disk encryption. Using UBCD4Win with the Pointsec plugin I can get access to the machines drive.
When I add the following boot.ini: /BASEVIDEO /BOOTLOG /SOS The machine does the following: * PointSec Authentication * List of drivers is displayed * A blue info screen showing things like: 2 system processors, blah blah, boot logging is enabled
Then appears a black screen showing the message Checking file system on C: The volumne is clean. windows has finished checking the disk.
That is as far as the system gets. I am really stuck for ideas on how to fix this (manually trying to copy in the old drivers didn't seem to help), or even to determine which update is causing the problem.
I'd appreciate any trouble shooting tips for failed XP boot ups.
