My system refused to boot. It says "no option to boot from". What do I do? I bought this laptop from Aliexpress and I've been managing it. But since today it has refused to boot. It will just show the first startup screen and it stops there. Before now, when it does like that, I'll just tilt the screen a bit and the boot process will continue. But now, no headway. The laptop has been having this flex problem. It cannot stand upright on its own. I have to wedge something at the back. Please, I just need to get it to boot at least just one more time so that I can evacuate all my important files from the system. Help. What do I do?
