I just installed Gentoo onto an SD card, not an the minimal ISO, the entire OS. I want to boot from the SD card, however it does not show up as a device to boot from, what should I do? Also how do I make it the default device to boot from?

  • why do you believe that your computer is capable of booting from an SD card?

    then it most likely will not boot from SD card ... if you plug in a blank USB thumb drive, then the thumb drive will show up in boot options ... put in a blank SD card and check the boot options ... it will most likely not be there

As I can't comment, you should first try:
there is a package for Gentoo there.

Also I think you should use the sd-card on a usb adapter to let it be recognized thru usb.

To make it default, you should configure it thru grub. Or if you mean in a hardware way, you should setup the BIOS to look at it first, if possible at all.

  • I want to put it in the SD card slot not a USB port.
