Nested Paging and 4.2

Description

Today I installed 4.2 and I have an error booting my live Windows 7 partition. It has worked in previous versions of Virtual Box with no changes. Unchecking Enable Nested Paging allows me to boot this VM. This setting considerably slows down the VM. The message is a -1012 error which seems to have something to do with privileges. I noticed that the new version has this in the change log, "VMM: improved VM context switch performance for Intel CPUs using nested paging" I'll be happy to provide more information if requested.
