Hey Fam,
one question… is there any option to boot from the sd card slot?
couldn’t find anything in bios.
i have a 128gb sd card and wanted to install prime os on it, but dont know how to boot from it.
even when i press FN+F7 it doesnt appears on the boot list.
any suggestions?
thanks in advance fam

Another cool and inexpensive way to use an SD Card for booting is with a USB SD Card reader. They come in normal, Micro and type C. I have a few 16 Gig SD cards laying around that I put various OS systems on and then use the USB SD Card reader. I bought mine for $1.50 on Aliexpress.
They look like this:
Thanks for sharing…
