I am judging the boot time from a stopwatch not the system and it is most certainly much longer. The Windows load screen seems to hang around for around 15 seconds. Whereas before it would be around for approx 2 seconds max. I can observe this 2 second waiting period with the hibernation function, but not the shutdown function anymore.
I have read this article to try and understand what is going on:
How Windows 8 Hybrid Shutdown / Fast Boot feature works - TechRepublic
Windows doesnt seem to be saving much to any file when i press shutdown as it shuts down really quick and I dont see much hard drive activity. & startup seems to be much longer due to not having the files and just performing a cold boot instead.
