I need to access the BIOS but the keyboard is not recognized until after windows is loaded. There is no PS/2 port on the motherboard. I have a system that uses a USB keyboard.

Depending on the size of the ISO image and the write speed of the USB drive, writing the image can take several minutes. Do not unplug the drive until the operation completes. The boot media creation process will begin. If the drive does not appear, verify that the USB drive is connected and restart Fedora Media Writer.Insert the appropriate hardware and change the BOOT options to load from it, as mentioned above. Otherwise, you can use software like MagicISO to boot from DVD. You can use an utility like Rufus to boot from USB. Use Startup Repair in Windows 10 Installation Disk Create a bootable Windows 10 installation disc.Then I tried something else, I selected my internal keyboar/trackpad, and tried FN+F8 again, and this time it worked!

oddly enough, it did not work with my USB keyboard, where the F8 button still didn't work, even after selecting the USB keyboard in the Devices menu.

An external mouse works but only to move the pointer, clicks and scroll do not work.

While installing Ubuntu 18.04 from USB or while trying Ubuntu without installing via live USB, the keyboard and mouse dont respond (I've set trackpad to 'Basic').

Or watch for a boot selector which is usually an “F” key during startup. Also you need to make sure your system is booting from USB before the hard drive in the system BIOS.

Have you downloaded and run the Memtest86+ USB Installer.exe? Just copying the file you download onto the USB drive won’t work.

There may be a fuse for the USB that was blown. Either your keyboard and mouse went at the same time, or the USB ports went bad. I'm running Win 10 + KALI linux this way and it is working perfectly. Any suggestions? I think the problem is with GRUB, we need to put it at the partition with Android itself, not to the Windows boot partition.

It is not problem when using included GRUB, but I can't make it running with Windows boot menu.
