Adapt to UEFI by reinstalling Windows.
Adapt to UEFI by reinstalling Windows.
I built myself a new PC last week. (Parts list is here: https://uk.pcpartpicker.com/user/Styxx1000/saved/m8HNcf , although I'm not sure that's much use for this issue) Today I realised that I've installed Windows on an MBR partitioned drive (NVMe Samsung 970 Evo Plus). This is my first build so there's a certain amount of learning for me here, basically I hadn't realised that this was a thing. I found another thread saying that UEFI needs the drive to be GPT partitioned. Also, this link was provided to convert: https://www.windowscentral.com/how-conve...windows-10 My main question is, is there any downside to converting the drive in this way, or would it be better for me to do a clean install of Windows? I've not done anything serious with the PC so far, so a clean install won't screw me, but if I can avoid having to set up everything again then that would be great. If I do need to re-install, am I likely to run into any issues with the Windows license key? Bearing in mind that I've already used it once, albeit on the same machine. Also, to convert to UEFI I have found two sections in the BIOS that mention UEFI, please see attached pictures. I think that I need to set the first one to UEFI, and that I can leave the second on LEGACY+UEFI. Is that correct? Many thanks to anyone who takes the time to read and reply.
The main benefit of using GPT comes when you have storage over 2 TB, and it works well regardless of how your operating system partitions the drive, as long as the disk meets the GPT requirements.
Was das wirklich der einzige Vorteil ist? Ich dachte, es sollte unter UEFI besser funktionieren.
It might boot a few seconds quicker with UEFI, but other than that there's absolutely no difference in your case. Once you're booted MBR (BIOS) and GPT (UEFI) perform identically. There is a very heavy performance hit (near 75% performance loss) for using GPT if you have very old hardware that wasn't built to support GPT, but that's a nonissue here.
