Hi Sathya
I think you can try to locate Primary GPT in LBA1 through block
IO->Readblock and check for signature in the GPT header
Uefi Spec Section
5.3.2 GPT Header
Signature 0 8 Identifies EFI-compatible partition table
header. This value must contain the ASCII
string “EFI PART”, encoded as the 64-bit
constant 0x5452415020494645.
Thanks
Ranga
