Windows 7 installation fails because of a GPT drive issue.
Windows 7 installation fails because of a GPT drive issue.
I checked online, but it seems just Diskpart formatting is involved. I don’t want to wipe my Windows 10 installation.
Windows Vista and newer (64-bit) all use GPT drives by default. Your source of information is noted. Edit: All Windows 7 installation images feature dual-mode setup and start with UEFI.
You're working with a 32-bit ISO and require a 64-bit version.
You can obtain an ISO file directly from Microsoft using your key. Or, let me know and I'll check what options are available.
GPT is a technology used for booting, while supporting it involves specific configurations. Vista and 7 do include GPT, but you can't boot from a GPT partition unless using UEFI mode. This information is widely recognized and available on Microsoft's documentation.
It clearly states the requirements. Your setup needs UEFI, 64-bit support, and UEFI boot activated. Otherwise it will fall back to the CSM which only recognizes MBR partition tables for startup.
I see you're debating 64-bit compatibility and UEFI, but the reality is very few non-UFE systems support 64-bit. It mainly applies to original Phenom 1 and earlier, plus first-gen core series and lower models. It's good to know, though—maybe you could have been more direct.
