Wrong reinstallation on inspiron 15R 5537, reinstalled win 10 Legacy mode

When I reinstalled win 10 using USB on Dell Inspiron 15R 5537, I changed secure boot to Disabled, and changed  bootlist option to legacy in BIOS.


After reinstallation, I found an error:

PXE-MOF: EXITING PXE ROM

How may I reinstall win 10 in UEFI mode? Now the system is legacy mode. I don't know how to set boot UEFI for USB priority. 


Thank you for your help.

I posted a response to your other thread.  Try not to create a thread for each question.

For your concern question, you can create Windows installation USB key using Windows Creation Tool.  Select to create for use with other machines.  It would be created in UEFI mode.  To boot the USB, tapping F12 at Dell logo for one time boot menu.  Select the USB key under UEFI boot menu and the installation will start.  At the selection of installation location, you need to delete every and all partitions on the HDD/SSD, then select Next to allow Windows formatting and creating partitions automatically.  When the installation is compete, your newly installed Windows should boot in UEFI mode.
