Elitedesk 800 G5 - restore bios factory setting without a monitor

[safrem]

due to a wrong bios setting the video output of my Elitedesk is disabled. To restore the bios factory setting using only the keyboard (assuming it works!) I need to have the complete step-by-step procedure, i.e.:

1) Press the Power button to start the computer and repeatedly press the F10 key to enter the BIOS setup menu;

2) press F9 to select and load the BIOS Setup Default settings;

3) Press F10 to Save and Exit;

4) Use the arrow keys to select Yes - how to select Yes?? Shall I move the arrow key Up or Down or Left or Right and click??

5) then press Enter when asked Exit Saving Changes - how to select Yes?? Shall I move the arrow key Up or Down or Left or Right and click??

6) Follow the prompts to restart your computer - how to select Yes using the arrow keys??

Thanks

Hello
unless I'm mistaken when asked to choose yes, you are already on it
so just clicked enter when asked to confirm

if not, check if you have the procedure by removing the battery

Hello, your suggestion for the keyboard does not work, so I followed the procedure by removing the battery, as suggested by you.

Problem solved! Thanks a lot
