Windows 10: how to switch back to the secondary monitor when my primary screen is bad while formatting

My hp laptop screen is bad and I have been using external monitor with it. I was trying to format the PC with Windows 10 on the process the first step was done and my PC restarted and couldn't show anything on the external monitor, and I can't see what's on the primary screen because it's bad, how can I switch back to the secondary monitor. I need help guys.

:)

 

The taskbar locked to bottom of secondary monitor moves to the primary monitor whenever primary monitor is switched on.

See the title.

I have the taskbar locked at the bottom of the secondary monitor so the primary monitor is completely empty for watching movies, games TV etc.

Whenever I turn the primary monitor on, the taskbar immediately jumps from the bottom of the seconday monitor over to the bottom of the primary monitor. I then need to untick the 'Locked' option on the taskbar, drag it back to the secondary and tick 'Locked'
again.

The taskbar disrupts desktop icons on the primary and any application running on the primary monitor at the time and quite frustrating.

Primary monitor is an Asus PB328, connected via Display Port to the PC.

Secondary monitor is a Samsung 24 connected via DVI to the PC.

I expect the taskbar to remain where I place it when locked, regardless of monitors been switched on or off.

The sequence of turning on the primary and secondary monitors has no impact. As soon as the primary monitor (Asus on DP) is turned on, the locked taskbar moves to the primary display, regardless of whether the Samsung is on or not.

 

Switch primary and secondary screen with keyboard shortcut

I have two screen one is monitor which is secondary screen and is in extended mode and another is laptop which is primary screen.
Whenever I open anything new it opens in primary screen(i.e. laptop) and then I have to drag it to secondary screen(i.e. monitor).

Is there any shortcut to switch primary screen and secondary screen which let me open file in screen where I have opened it?

 

Can you put the taskbar on a secondary monitor and not on the primary monitor?

I want to have my secondary monitor have my taskbar and all my shortcuts and my primary monitor be solely for display. Is there a way to only have the taskbar visible on a secondary monitor without setting that monitor as my primary monitor. I've tried setting the other monitor as the primary monitor but apps will default to open on that monitor and I don't want to have the taskbar on both monitors or to automatically hide. Thank you.
