Windows 10: I have installed windows 10 in Legacy boot instead of UEFI

I'd like to change it to UEFI because it boot faster than legacy. But whenever i change it it shows no bootable device. Also i would like to ask what's the difference between the two

:)

 

Windows 10 UEFI BIOS

It looks like your hardware supports both the new firmware standard (UEFI), and the old firmware standard (Legacy or BIOS).

Based on your description, it seems that Windows 10 was installed in UEFI mode. Legacy firmware can't see UEFI, and that's why when you enter Legacy, you can't see the newer, UEFI-based Windows 10.

The solution? Reinstall Windows 10 using legacy boot instead of UEFI.

Hello sir I have recently installed windows 10 on my Lenovo g500s in legacy mode but now i want it to boot from uefi mode. Can i change boot order from legacy to uefi without reinstalling windows or losing data? Plz sir help me figure this out because legacy
mode boots very slow.

just converting the drive to GPT wont make the system boot in uefi mode. because windows will still use legacy winload and unless you change the boot loader to use winload.efi.

 

One thing that is not a difference is that it won't boot any faster. Maybe a fraction of one second at most. The biggest difference is the number and size of partitions that you can have on one disk/SSD.

 

Thank you for your replies, are there any features of windows 10 that wont be available in legacy? because it says that it is recommended to boot in uefi than legacy in windows 8-10.

 

You don't lose any features of Windows.
