Non UEFI mode in windows 8.1

[Compman55]

So for older laptops the only have a ACPI bios with no UEFI support, will windows 8.1 be lacking any features? I know the quick startup is not an option, but compared to win 7 would there be anything lacking?

Windows 8.1 Per-Se would Not lose any Features.

The Most significance difference is that Legacy take few second more to finish the Boot process.

Actually the opposite does occur. I.e., people need to Run Apps that are only working on Legacy and they would Not Run if UEFI is On.

Explain the legacy apps thing. Once windows is up and running, does it matter? I thought the issue was running things before the OS loads, like memory diagnostics, disk utils and diags, etc.....

Been running 8.1 on two ACPI desktops (P5NG mobos) with no problems. Have also two of those with Win 7. My 8.1 is modded with Start8 1.43. For me it is Win7 on steroids. 🙂

The main benefit is that Windows 8 can interface with the UEFI and tell it things like, "next time you boot, please enter UEFI setup" or "next time you boot, please boot from the flash drive instead". Mostly, it saves me the trouble of...

1) remembering what magic key (Esc, Del, F2, F10, F12, etc.) I need to madly press during boot (since evidently after all these years, people still can't agree on one)

2) madly pressing said key during boot and timing it just right (esp. a problem on UEFI systems where the boot happens so quickly that the window of opportunity is unusably low).

Aside from that, I haven't really noticed any other advantages. Besides GPT supporting boot drives over 2TB, but that's usually not an issue if you're using SSDs.
