I am not sure if grub can boot off GPT without UEFI. I honestly never thought of this. For me both go hand in hand. The GPT is part of the UEFI specs (https://en.wikipedia.org/wiki/GUID_Partition_Table). And thank you for bringing the context to my memory. Regarding support in windows look at the tables of the WIKI link at the end of the page. It says it requires UEFI to boot in all versions of windows 64 except server, while on 32 it does not support booting at all around those years 2001-2009 (up to win7). And the note: "MBR takes precedence in hybrid configuration." It might be that to boot off from the drive, OP would need to setup UEFI and disable MBR boot completely. regards PS: Sorry but I was just thinking of trying to add a turbo on 1920 car :)
