How To Have Pinephone Ignore MicroSD On Boot?

[britelite]

Let's say someone had a boot file on their MicroSD card, but they wanted the Pinephone to ignore it and to boot from the internal eMMC, while the MicroSD card is inserted. Is there any way to do this, to hide the file somehow?

Because what if also you don't have a file like that on MicroSD, but loaded some files, and the Pinephone won't boot because it seems to be detecting some file as a boot file, but does boot when you take out the MicroSD?

Is there any way to force the device to ignore the MIcroSD card on boot, or has anyone had any issues of the MicroSD card preventing the device from booting on startup and how did you get it to ignore files it might detect and try to boot from?

As per @wibble if you want your SDcard for data only.

Use megi's p-boot if you want to dual boot.

(Of course if you mean PinePhone Pro and not PinePhone then things are different - use Tow-boot on SPI to get dual booting on a PinePhone Pro.)
