so the PC works ok now, right,????
and BOOT HDD passes F12 diagnostics ok, right?
I guess you mean , you want the HDD too boot in w10-64bit, SECURE BOOT mode and sure that is GPT.
what it now.?
and what is the end goal.?
is this a 2TB boundary issue or just secure boot and wanting to end legacy boot.
please say thanks,
ahh the fake desktops I call Hockey puck PCs.
all I can see is go into BIOS and turn that on, most PCs to go from legacy MBR boot to secure UEFI takes freash OS installed.
and just before setting up BIOS to SECURE BOOT ENABLEd.
btw my boot M.2 drive is set to boot GPT in non secure boot mode, due to my wild GPU swap outs. so there is one more way.
Installed like that.
yes do avoid MBR boots today, no need to use that.
NO warranty answers by me.
