Can't access BIOS on Samsung Slate XE700T1A

When I turn on the tablet, I always get a screen for "SAMSUNG" but then:

Windows Recovery Environment. Your PC needs to be repaired. A required device isn't connected or can't be accessed. Error Code 0xc0000185. Your PC doesn't have the Windows Recover Environment installed. ...

Any attempt to access BIOS (Holding Win Key while turning on or holding Volume Key while turning on) fails to produce any results, although sometimes this does result in a split second screen that says "Windows Devolper Preview. Preparing automatic repair", but then continues to the Error screen.

I'm attempting to get into the BIOS to turn on the boot order to boot to USB first so I can overwrite the OS.

Is this thing a brick now?

I had the same BIOS entrance problem so many times. The problem is Windows has fast startup option to reduce the time it loads OS.

To do this it overwrites legacy Options in BIOS.so you cannot enter BIOS with old key combinations also you have limited time to press hot key.

Default hot keys are Del + F8 , Or Del+F10 or Del + Esc or Del with something

Windows button is not usually used to enter bios, but for the Samsung slate, which has no keyboard, the windows button is used to enter the bios. Immediately after turning the power on, depress the windows button and hold it down until the bios pops up. Then you can navigate in the bios using the volume buttons, the lock button (next to power button) as enter, and the windows button as esc.
