Installing Symantec Endpoint Encyption (SEE) on systems that have the Virtual PC Health Check installed may cause the system to stop booting.
Symantec Endpoint Encryption and Windows 7 with Virtual PC Health Check
When you try and boot the system you will be presented with the "Press F3 for Virtual PC Check". During a normal boot, you would ignore this message and let it timeout. However with Symantec Endpoint Encryption installed after the message has timed-out, it will simply re-appear and the boot process will not continue.
If you press F3 you will get a message that says "NF" and the system will not proceed any further.
Installing Symantec Endpoint Encryption on a system that has the Virtual PC Health Check installed. Virtual PC Health Check uses boot code that doesnt work when the partition layout is changed by programs such as Symantec Endpoint Encryption.
1. If you are deploying an Operating System image, use the option in your disk imaging software to remove Virtual PC Health check by deleting the entire contents of the hard drive (for example, use the DISKPART CLEAN command).
2. If you are not deploying an image, or if you are already at the point where the system cannot boot, you will need to use the recovery process below:
Stage 1 - Boot from the Windows 7 DVD
Stage 2 - Start the Recovery Command Prompt
Stage 3 - Repair the Master Boot Record (MBR)
This will have now stopped Virtual PC Health Check from running as the Master Boot Record (MBR) will have been replaced. This should allow the system to complete booting while Symantec Endpoint Encryption is installed.
