Cannot Boot with HP Secure Mode after Reinstall Windows with Legacy Boot Device

When you install Windows using a Legacy Device is marks the Boot Volume with an Master Boot Record (MBR) label

I use easybcd to load all my ISO’s on a single USB which doesn’t support UEFI 

You need GUID Partition Table (GPT) for UEFI Boot

You can check this via Disk Management

Restart the PC into Safemode with Command Prompt

Run this command to make sure the drive can support GPT 

mbr2gpt /validate

Then Run this 

mbr2gpt /convert

After this you need to change the Boot Loader to use UEFI instead of Legacy
