Hello.
I have an ACER laptop (w8) that as soon as it's powered up it shows the message "No bootable device -- Insert boot disk and press a key to continue"
Funny thing is I cannot enter BIOS no matter what. Tried tapping F2 key repeatedly. Tried with an external keyboard. NO dice. Both keyboards seem to be working but I cannot enter BIOS.
Any ideas?
Partial success: After removing the hard disk, I CAN boot w10 installation from usb.
Any ideas on how to proceed from here?
SUCCESS!
After connecting hard drive on the fly, now press F2 and press F12 keys appeared on main screen.
I was able to enter BIOS. Loaded setup defaults and reconfigured bios to allow F12 key to choose boot device.
FWIW: Someone has destroyed the original ACER w8 GPT partitions and installed Windows 7 MBR. Installing w10 now (GPT). That's why it couldn't boot. BIOS had reverted to UEFI boot.
Well, you're sorted now, but for the future - F2/F12 won't appear as options at boot if the Acer thinks it is resuming from something like fast startup rather than performing a cold boot. A hard reset would be a way around that. It would appear that after replacing the drive that's effectively what you had done.
Assuming you hadn't cloned or otherwise turned the new drive into a spittin' image (pun intended) of the old one, getting a new system/boot drive up and running would definitely do the reset thing, though, wouldn't it? That was my thinking, and my source of amusement in the original response. Thanks for reminding me that there are many more ways to get into (and out of) trouble in Win10 than you or I can come up with on our own. That's we hang out here at TF!
Thanks, as always, for your input and ideas here on the forums.

I would image that on the HDD removed and then replaced, that a flag had been set, and the hiberfil.sys was intact.. So, it picked up where it left off, grabbing it's "where am I?" from the hiberfil.sys. Guessing out loud............
