Acer laptop - fresh install of Win 10
Had to change BIOS to boot from legacy as it was from a DVD
All installed OK
Go back to BIOS to change to boot from UEFI and Secure Boot, and it won't boot
Thought it was best on UEFI
Any Ideas - Thanks

A windows 10 install DVD should boot with UEFI enabled. You do not want to install Windows 10 in Legacy Mode on a UEFI computer if at all possible. 


Follow the below guide and use Rufus with a USB flash drive. Use a GPT partition scheme in Rufus and the convert GPT command shown in the guide.




Microsoft has a conversion utility to change an MBR disk (Legacy Mode)  to GPT. If you do decide to use it backup any data you need even thought the utility is said not to affect your user data. I have never used this tool so it would be interesting to know if it changes the partition structure.
