FAST BOOT Causes Lockup After Welcome Screen?

Laptop is Lenovo X220 that had Windows 7 Pro and upgraded to W10. It has had already 5 vanilla installs of 10 Pro 1511 on it.

2x install with an old 3.5" 5400 RPM stock HDD drive and the 4-5th and final install with an upgrade to an SSD. The HDD was changed to SSD because of me thinking the HDD was dead and was causing the computer to lock up at boot.

Tried 3 different operating systems on the machine as well, Windows 7 (no problems) (stock with computer), Windows 8.1 (with Fast Boot) enabled and no problems on Windows 8.1 O/S and finally W10 PRO 1511, vanilla from Microsoft directly.

For some reason after W10 installs, does its updates, reboots, drivers are updated and everything seems fine after a couple of reboots and such. Works normally, wakes up from sleep. Only 3 programs get added. Firefox, Chrome and WinRar.

After that shutdowns OK, but when she boots up it gets past the welcome screen and hangs on the desktop. Complete hang everything becomes unresponsive, but the mouse pointer. I can dance the pointer around but No keyboard input no GUI input, nothing. Only way to come out is with a POWER BUTTON DOWN. Was trying to solve this issue since December and never found any solution, thought it was drivers or internet, or hardware but nothing, no dice. Even if it didn't connect to the internet after install and a program or 2 were added via USB and I shut down it would hang upon next boot.

So I did reading and reading and researching and I came upon a thread that mentioned W10 hangs on welcome screen with Fast Boot on, I thought no this can't be it because I make it past the welcome screen. I hang on the desktop when I'm actually in Windows. I can manage to click Start button and the system will hang. Only way to get it to respond is to hold down the power and power it down. Temps seem OK, MEMTEST came back fine, replaced HDD with SSD, only other thing I could think out was drivers or hardware (mobo) failure or something else ....

Then I decided to clean install update drivers via Internet, reboot and then disable FAST BOOT via @Brink regedit hack, because for some weird reason, on this machine on every clean install, FAST BOOT IS NEVER SHOWED in the POWER menu. I could not understand this. I do not have this option at all like @Brink has in his diagram photo. The option is just not there!!! But the registry though the hiberbootenabled value is set to "1".

So two questions, why is it checked and greyed out (that I cannot uncheck it) and 2, the only way I was able to change the value was manually via @Brink registry edit.

OPTION 2 - using a bat file because option 1 was unavailable.

Once I disabled FAST BOOT, the laptop has been fine since. No locking up anymore period!

SSD is 850EVO and W10 PRO is the only O/S on the machine, legit with digital entitlement upgraded from W7 PRO key on the Lenovo, because its an X220 thinkpad so 'business' series. No problems since.

#1 Fast Boot option to disable on startup is not avialable on the machine? Value is "1" in registry but cannot make changes to it via control panel as it simply is just not there. (This was the case with both HDD and new SSD). Windows 8.1 shows the option, not 10.

#2 Hangs on startup after welcome screen

#3 Only way to prevent is to run the .bat file from @Brink or manually edit value in regedit, save, exit, shutdown, go on with life.

AFAIK value in REGISTRY is set at '0' and machine works ....

Brink has this option on his machine via control panel but I do not on the laptop. Brinks:

My PC does not give me that option at all. Is if it doesn't even exist.
