I'm skipping to the bottom of this thread but some vendors have reboot to legacy BIOS as a W8 option, because the POST during secure-boot or "ultra fast" boot is complete before the keyboard is active.
You'd need to look up the specific vendor of your laptop to see if it's one of these.
You can try holding the ESC key or the PAUSE/BREAK key during secure boot too, some laptops (Lenovo, Samsung) revert to the BIOS or at least a menu with this method.
Can't reboot to legacy, sadly. I will try hitting esc and various other likely candidates during boot to see what I can get.
Nothing I can find in the literature for this laptop model about it, so we'll see...
Use google to see how to install "Linux" onto the laptop model, most likely someone will have figured it out. Some laptops now require stupid utilities because they ALSO neglected to include a UEFI loader shell.
I did come across some Linux talk, but nothing that really applied to this particular model unfortunately.
I don't have the model memorized and it isn't in front of me now. It's an Acer, but the model numbers on those things is like 20 characters. Starts in E1, ends with 4402, but there is a lot in between. Will update later...
