Boot – Should Ubuntu Be Installed as UEFI or Legacy

bootsystem-installationuefiwindows 7

I began to install Ubuntu, but got a message about UEFI/BIOS compatibility and how I wouldn't be able to boot both.

If I install as UEFI, will I be able to reinstall Windows 7 as UEFI? Or should I just install Ubuntu in legacy mode?

Best Answer

To prevent needless complication, I would advise that you install Ubuntu in the same fashion that Windows is currently installed.

So, if Windows is installed as UEFI, it would be best to install Ubuntu under UEFI such that you don't need to swap bootloader modes or reinstall Windows to change OSes. Similarly, if Windows is in Legacy mode, install Ubuntu in the same.

If it really doesn't matter to you, though, I'd highly suggest using UEFI. It offers many more features that can come in handy on modern systems, and can allow for better compatibility with graphics and hardware stacks on modern systems. All in all, though, it really doesn't matter after you get past the bootloader.
