This is a bit of an abstruse story lol.
I opened up my all in one pc to see if it had an m.2 slot and when opening it I accidentally ripped the LCD screen connector off so the built-in screen no longer works. I put in an m.2 SSD and upgraded the ram anyway. When I tried to install windows onto the SSD with a USB drive I realised the bios and boot selection screens only come up on the built-in monitor even with my second monitor plugged in. I managed to boot into a Ubuntu USB blindly with windows advanced startup which only displays on the built-in monitor and then tried to clone the disks in Ubuntu but it didn’t work. Now when I turn on my PC the screen goes black and the fan starts spinning, I think I may have messed up the windows install on my hard drive. Is there anyway I can boot into a windows installer USB drive and have it appear on my second monitor rather than it trying to display on the unconnected built-in monitor?
