Partition Table Does Not Exist on Device
by G-MAN2021 from LinuxQuestions.org on (#5FKCW)
Hello,
I'm using the Control4 system in my home. The controller (EA-5 v1) for the system is running a linux flavored OS. The boot files is on a eMMC chip.
Based on the screenshot below, it looks like partition 1 is invalid. How can I recreate or repair partition 1 without losing data.
I can provide more information if you need it.
