Dual Booting on the UConsole

[Abdallah_Natsheh]

Hello everyone!

I’ve been working on setting up dual boot on my UConsole—one system for playing retro games and another for security testing. Since managing both on a single SD card is quite complicated, I decided to try a hardware-level solution for dual booting. After some searching, I came across this handy SD card switcher on AliExpress:

The Setup:

I’ve got two SD cards—one running Debian Bookworm and the other running Parrot OS (both images from Rex - thanks to him). At first, things didn’t work as expected. But after a bit of research, I found a solution that worked perfectly. Here’s the resource I used:

How to Fix the Booting Issue:

If you’re trying something similar, here’s a simple summary of the steps I followed:

1. Backup cmdline.txt: Use this command to backup the file in case something goes wrong:

sudo cp /boot/cmdline.txt /boot/cmdline.txt.bak

For Bookworm, the file is located in /boot/firmware/cmdline.txt.
2. Edit the cmdline.txt: Open the cmdline.txt file and find the line that looks like this:

root=PARTUUID=xxxxxxxx-xx

Replace it with:

root=/dev/mmcblk0p2

3. Add a Debug Quirk: Append the following at the end of the cmdline.txt file:

sdhci.debug_quirks2=4

Now, I can easily switch between operating systems. All I have to do is power off the UConsole, flip the switch on the SD card adapter, and boot from the SD card I want!
