Update: I'm trying a new P2V conversion after disabling my Norton AV software, and this time I'm using an external USB mass storage device to save the disk image to.
I'm also erasing the Data partition on my HD (the partition I used to save the disk image to, which was obviously not included in the conversion though) so I can save up some space.
Last, I will include in the P2V conversion process the HP Recovery partition too, so I can have a 100% exact copy of my HD without any of my "customizations" which could make thing worse.
I will report as I'm done with it.
