[SOLVED] Bios to Uefi?

[Gandros]

Hello lads, i just upgraded and bought a b450m pro4 and a ryzen 5 3600 and was wondering if i had to reinstall windows 10 onto my hdd if i was switching from bios to uefi, a friend told me i had too and i wanted to get a second opinion.

Yes, you need to reinstall Windows after a motherboard change. Even if it's Windows 10 a reinstall is advised to avoid any glitches or issues either now or at some point in the future.

Nothing to do with BIOS versus UEFI, it's simply because it's a different motherboard with different hardware so the existing Windows installation is no longer valid (wrong drivers, invalid registry entries etc.).

if you have a new PC you will want to reinstall win 10 anyway to get better performance

Have a look at this and set windows up so you can move licence - https://support.microsoft.com/en-us/help/20530/windows-10-reactivating-after-hardware-change

The format will look after the swap.

There are ways to convert W10 from legacy to UEFI BOOT https://www.windowscentral.com/how-convert-mbr-disk-gpt-move-bios-uefi-windows-10 but you would be better off to reinstall windows. If you have only W7 the path is practically nonexistent.

UEFI can boot quicker, but it´s not necessary to reinstall windows only because of this. But it would make sense to reinstall windows because you are using a complete different configuration and drivers from the old system which might interfere. Performance might not be 100% or BSODS/errors could happen sometimes
