Partial boot after installing Manjaro on emmc

[regivanx]

Thank you very much for your answer.

Can you check if I understood your answer correctly before entering this shell code?

Code:

$ sudo -s
# cd ~
# mkdir uboot
# cd uboot
# dd if=/dev/mmcblk2 of=uboot_backup.img bs=1M count=16
# dd if=/dev/zero of=/dev/mmcblk2 bs=1M count=16

After this last operation, the first 16 MB of mmcblk2 will be overwritten, and uboot with it.

Can you check the above code carefully? As I use dd, I would like not to trigger a disaster.
