Venue 11 pro Boot AndroidX86 from SD, not only from USB

Hello !

I have EFI AndroidX86 installed on SD 1x Samsung EVO32GB and 2x Kingston UHS1-16GB.

When any is inserted into SD-USB adapter, AndroidX86 will boot on my Venue 11 pro successfully (USB mode).

When the same is inserted in built-in SD slot, i can see it from Windows Explorer, but it will not boot AndroidX86, and SD will not be available in UEFI boot sequence options within BIOS setup meanwhile.

Installing GRUB2WIN, to run GRUB BOOT from C:\ , THEN select Windows or AndroidX86, did not help, as it keeps searching for Android…………………………………………………………………………………………………………………………………………………………………………………………..forever,

Has anyone successfully loaded AndroidX86, from inside SD card, on venue 11 pro ?

I would be so thankful if you can let me know what is your SD model, and if your SD is GPT/MBR, FAT32/NTFS/eFAT, and if your BIOS allows Legacy BOOT, or is set as EFI mode only.....
