flashing a micro sd

[ocean peak]

Hey im tring to flash a micro sd ive never done it and I got confuzed any help please?

you want to put an iso on it?

run fdisk -l and note which /dev/sdX device the SD card is

then sudo dd if=<ISO PATH> of=</dev/sdX> bs=4M status=progress oflag=sync

for example, if your ISO is at ~/Downloads/archlinux.iso and your SD card is /dev/sdc:
sudo dd if=~/Downloads/archlinux.iso of=/dev/sdc bs=4M status=progress oflag=sync

made double and triple sure that you are targetting the correct /dev/ device. if you type the wrong one, you'll erase the wrong drive

it may also be named something like /dev/mmcblk

also note this will erase whatever is currently on the sd card, so make sure there's nothing important on it

most BIOSS don't support sd on the other hand if you sd to usb thats diffrent

yeah i've used a micro-sd card with a usb adapter to boot archiso, never tried it with a system that has a direct sd interface

i think some laptops use sd-to-usb internally even for the sd card slot
