What is Fast StartupHave you observed how fast Windows 8 boots up when compared to Windows 7? Pretty fast, isn't it? With all the brand new features came a feature called Fast Startup. What this feature does is, when you shutdown your Windows 8 computer, it stores some data, like kernel session, device drivers, system information, in a file in the system level memory and when you switch it back on, Windows uses data stored in this file to resume your system and since reading this file and re-initializing of device drivers is much faster, it significantly rises up the boot speed and if you have a UEFI supported motherboard, then the boot time will be even faster.
Why should it be DisabledIt isn't actually supposed to be disabled but there are certain things that doesn't like this technique. First let me tell you a simple problem I faced. When I switched my laptop on and logged in into Windows 8, the Modern UI was not getting initialized or loaded. I was getting a blank screen and had to restart my laptop to get things working again.
Note here that the Fast Startup doesn't come into picture when you Restart your system. And disabling fast startup solved my problem. But this isn't enough reason to turn it off.
The Main ProblemDo you plan to Dual Boot your system with any other operating system? My answer is, Yes. Then here is your biggest headache. Shut down windows, boot into the other OS, restart and boot back into Windows 8. Voila..! You've got a corrupted Windows..! What happened here?
Here is the explanation, Windows stored this file, we talked about, in the system level memory. When you booted into the other OS, it needed system level memory. It found some junk. It ripped it off and cleared the memory so that it can use it. There goes your Windows! When you booted back into Windows 8, it went like WTF..!
