You can’t go past that BIOS boot screen? Got stuck?
Did you got PXE LAN boot ROM screen or just a message that say “no OS installed” appear?
Did you try ESC, DEL, F12 or any keys that BIOS mostly uses? https://tubemate.vip/ , https://videoder.pro/ ,https://snaptube.vip/
Is your laptop warranty still valid?
If yes, you can RMA your laptop. Because BIOS problem can’t be fixed easily.
