If you can boot into Windows, and access the files, then back them up now!
I would call McAfee support to fix it at this point, although I would say at this point a rebuild would be the easiest.
Guessing, I would say that aan MBR restore is in the offing. Did I mention that you should back up the data now??
Thanks for your advice.
I got it, with a reinstallation of the MEE client and let the security team set it to decrypt and remove.
It took me three full days to get this machine up and running. Hopefully the user is happy now.
Did I say: Thanks for your advice! ?
