What I've tried and the error I got/why it didn't work:
- using dd to turn the micro sd into a .iso | failed to boot FATAL: Could not read from the boot medium! System halted.
- using dd to turn the micro sd partitions into individual .iso files | failed to boot FATAL: Could not read from the boot medium! System halted.
- using dd to turn the micro sd partitions into individual .iso files then mounting the .iso files at the correct locations (msdos boot partition mounted at /boot/, and ext3/ext4 root partition mounted at /) | i can't find a way to edit the mount point of a .iso
- mounting the original sd card as a usb device | virtualbox does not recognize any availible usb devices even though they're there, probably because I'm using a linux host
- mounting the whole file system as a shared folder | failed to boot FATAL: Could not read from the boot medium! System halted.
- installing a normal raspian system and shoving in parts of the original file system from there | i could not convert the .img raspian image to .iso ccd2iso:
Unrecognized sector mode (c0) at sector 0!
Host: x86 | arch linux | virtualbox 6.1.36-1 with extension pack 6.1.36
Guest: Raspberry pi 3b+ | raspian
Does anyone know how to do this? Is it even possible? Thank you!
