Boot device not found or whatever

[StarStrucker]

Hi, I need help on how to get windows again. This problem has been stressing me out for 2 full days now. I've followed youtube tutorials, explaining how I need to get to the BIOS Setup and disable secure boot or switch up the order of the UEFI thingy (there was no option for legacy boot). I genuinely need help. Someone please get to me on this. It feels like Microsoft is **bleep**ing me over. My mom is taking it to a tech geeks to repair it but I have little hopes as of now.

My laptop is a HP Laptop 15-ef2126wm

Thank you a lot for this! I didnt do your method but I reinstall windows but had to get all my data back which was a pain. Is there any way to not let the "sign in options are disabled" to never happen again?
