Windows 10: Stuck on boot at "Please press DEL or F2 to enter UEFI BIOS Setting" message.

Stuck on boot at "Please press DEL or F2 to enter UEFI BIOS Setting" message. I unplugged all USB devices and restarted the computer. I haven't changed any of the hardware GFX card, RAM etc. It won't move on from that screen. Please help.

PC stuck on "Press Del or F2 to enter UEFI BIOS". What to do?

I have a Dual Boot Setup with Windows 10 on a 250GB SSD (SSD1) & Ubuntu on a 128GB SSD (SSD2).
Running on a Z97-Pro Gamer Motherboard with an Intel I7-4790K, Nvidia GTX 970 & 16GB of RAM.

Until last monday everything was fine. Then I was browsing the internet from Firefox ESR under Ubuntu and for some reason, the PC got stuck. Nothing reacted so I had no choice but to reset the PC. After that it rebooted, but got stuck on the "Press Del or F2 to enter UEFI BIOS".

Reading up on the issue (from my cell phone) I found out it might be caused by a USB device. So I unplugged everything USB (end went a step further & also unplugged anything not essential inside the case as well), leaving only my wireless keyboard & mouse connected.

Booting it up got me into Windows just fine. Then I unplugged SSD1 & plugged SSD2 back in. Booting went past the "Press Dem or F2 to enter UEFI BIOS" but was very sluggish & eventually produced an error being unable to load Ubuntu.

Assuming something wrong with the Ubuntu install, last night, I formatted SSD2 & re-installed Ubuntu. After that, I was unable to choose Windows from the GRUB menu since there was no entry. I was reading up on fixing that when I went to bed. This morning, firing up the PC, I once again found it stuck on the "Press Del or F2 to enter UEFI BIOS".

And I'm clueless (besides a potential faulty SSD?) what might be causing this. And how to solve...

Stuck in UEFI after reset to default.


and if your Bios is set for UEFI booting. You would have to enter bios setup to confirm that which is usually pressing DEL repeatedly, (or it could be F2, or whatever the key is for your particular motherboard) when first turning on the computer.
