After messing with eMMC partitions, PBP won't boot, even from SD card

[imij]

Thanks, disabling the eMMC let me boot from SD. Now I'm running into another issue: the OS can't seem to detect the eMMC at all now, even when I re-enabled the switch. I experimented with enabling the eMMC during different times: during boot, before login, after login, and it still won't be listed.

Code:

rock@Debian-Desktop:~$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
mmcblk0 179:0 0 59.5G 0 disk
|-mmcblk0p1 179:1 0 64M 0 part /boot
`-mmcblk0p2 179:2 0 59.4G 0 part /

It is only listing one disk, which is the SD card I booted from.

Is there any way to fix this, or will I need to wait until I get the eMMC USB adapter to flash an OS that way?

Thank you
