Hello 

I wanted to change my Bios boot mode to UEFI (Secure Boot). Currently I am running Legacy mode. But since after I made the change I will then have to reformat my drive from MBR to GPT and reinstall Windows using GPT-compatible media. So can anyone help me how can I do that without losing my data ?
