Hi!
My Acer Iconia is modified witha bigger mSSD. I didn't replicate the secret partition. Original mSSD is fried. I was able to access BIOS using the WinKey + Power but recently, the installed Windows (8, 10, or 8 upgrading to 10... I cannot rememeber) did something and the machine boot directly to this:

And stalls there. Nothing works. Now, i cannot dot he WinKey + Power to access the BIOS. The device doesn't load from and USB Sticks and/or USB DVD. I found the recovery Disks (somehow: Torrents) but they proved all uselss as they are not recovery disks at all as they are dependent on some stupid partition which is beyond all reasoning. Three Disks and all fail.
I need to understand why I'm not able to access the BIOS anymore? I have the Keyboard dock attached.
Thanks.
