Rosa 11 LHD

[nice2meetu888]

Hello everyone!
I recently installed the official Rosa 11 LHD on my tablet via a USB flash drive using Rufus. I installed the system on a 32GB microSD card (the internal eMMC is damaged, and Windows crashed). The installation completed successfully, but the system does not boot afterward—it keeps jumping back to the flash drive.

I've been searching for solutions and found some related threads, but none that directly address booting from a microSD card using the correct GRUB setup. I'm unsure whether to format the card as GPT or MBR for the bootloader, and I see suggestions about using DD, but I'm unfamiliar with how that applies here.

Any advice on how to properly set up GRUB on the microSD card to boot Rosa Linux would be appreciated! Should I use GPT or MBR?
I can provide logs, screenshots, and more details if needed.

Thank you!
