I'm trying to understand what it means to boot into a GPT-initialized disk on UEFI system.
In the world I live in Windows only boots to MBR disks. But I keep reading that it is possible to boot using GPT. Few questions arise:
UEFI seems to exist only if the hardware supports it. How do I check if my (new PC, HP Z440) has it?
How does booting to GPT work (there's no boot record!)?
The real reason I bring all this up is because I am trying to install Windows 10 onto a brand new SSD (OWC). I failed. Here are the details:
When 1st plugged in, the motherboard didn't even recognize the SSD
Then I plugged it in via USB and it was seen. I mirrored my existing drive onto using Acronis
When I plug it back into SATA and try to boot, I get irql_not_less_or_equal error (which is a driver error, when it tries to access an illegal memory address space, from I've read)
I'm trying to update the firmware on the drive now, which could be a solution
I am exploring options to get this fixed, thus the questions about using GPT.
