DietPi on UGREEN DXP4800?

I’ve been considering using DietPi on my UGREEN DXP4800 Plus NAS and wanted to ask if it was worth it. It already came with a pre-installed OS but I find it limited and am unsure whether to migrate and where to migrate to.

IDK if it’s possible, but you will lose your warranty if you install a 3rd party OS on the UGreen NAS.

I’m fine with losing warranty. I still left the base OS (UGOS) on the SSD so i think it should be fine either way

I’m having an issue where using the UEFI installer immediately takes me to the grub CLI and BIOS/CSM loads the installer but had some error having to do with the kernel. I additionally tried doing debian → dietpi-install but that resulted in a blank screen with only the blinking command line cursor, and when re-booting into debian being encountered with a CLI.

Is there any way to get around this or is DietPi simply not supported on ugreen nas?

officially? nope we don’t have tested this.

where at which stage if the installer??

Do you know whether this NAS supports 64-bit EFI binaries? There were some Intel box cases which support 64-bit distros but weirdly 32-bit EFI only, which is neither supported (shipped with) our x86_64 images, nor dietpi-installer.
