I am trying to boot from micro sd card, can’t get into UEFI settings, computer doesn’t show anything

[dawn ermine]

I am trying to boot arch from a micro sd card on an old laptop with a internal reader. when trying to get it to boot I disabled my old distro and windows when trying to boot, it then got stuck on grub rescue(I messed around with kali) and now doesn’t show anything when powered on and quickly powers off. what should I do, also I know it was a dumb idea, thank you in advance

Also the computer is a dell latitude 7490

spam boot to bios/boot menu

or reset cmos

How do I reset cmos safely, I’ve tried all the keys for boot menu

take the laptop apart, and you’ll find a coin battery, if it’s soldered, unplug the ssd and see if it’ll let you boot, then put the ssd back in. if it has a cable, unplug, wait a few seconds, and plug back in. if it’s socketed, take it out, wait a few seconds, and put it back in.

I unplugged the cmos and put it back in, then I took off the storage, still won’t work
