I compared it with mine, and it seems the FAT32 (EFI) partition should be
required and with GPT attribute
0X0000000000000001.
When you will be able to use diskpart, you should select that partition and then run these commands:
Code:
GPT ATTRIBUTES=0x0000000000000001
active
If you have a minitool partition wizard bootable (USB) media, you can likely also change the "partition type id" from there (it seems it is already correct, but maybe it will change also those attributes? Who knows).
