original Beelink GS1 partitions

  • Good morning, a few months ago I bought a GS1 TV box. The Android system doesn't boot at all, it appears jerky. I thought I'd try Libreelec since it's fully supported. Libreelec boots without any problems, so I thought about installing it to the internal memory. But I have some questions about what might happen if I install Libreelec to the internal memory and it then doesn't boot. Will I lose the ability to boot from the SD card?
    I noticed that the internal memory has some partitions that I'm not sure about.
    Thanks in advance to anyone who can help me.
