Purchased a new laptop and overlooked turning off the UEFI BIOS prior to installing Windows 10 Pro X64. During startup, the machine displays "Invalid partition table!" message. When accessing the one-time boot menu and choosing UEFI: Windows Boot Manager, it boots normally. It seems the device defaults to legacy boot from the hard drive instead of UEFI. I've adjusted UEFI: Windows Boot Manager to prioritize it over any legacy settings in the BIOS, yet the error persists. Should I disable legacy boot completely? Would a full reinstall in Legacy mode be preferable? Thanks!

It's been quite a warm period since I experimented with a Latitude from that era, but I believe that's likely the simplest answer. Why? UEFI performed well during the Sandy/Ivy Bridge timeframe.

I need to keep supporting my ability to start from older systems. Usually I turn off the UEFI BIOS right away, but I missed doing that earlier.

Have you checked the source? It might have been a typo. Renaming the EFI folder inside the data partition could work if it exists. This sometimes resolved my boot issues, but likely not for a fresh installation.
