Neither of those are helpful.
There are several needs for this boot disk. We have machines in remote locations that don't have network access and need bootworks removed.
Times past we made bootworks uninstallers that just booted up and automatically removed the bootworks partition. The new uninstaller doesn't do anything.
We also have the odd machine that gets an "Invalid LBAI" error. Removing bootworks with a disk quickly cured the issue.
WinPE2.1 bootworks uninstaller worked but we still had to run BWINST.EXE -u The new one for WinPE4 doesn't seem to work the same.
