Yes, my USB is FAT32 formatted and using the GPT partition scheme for UEFI BIOS.
Secure boot is disabled and pc is set to boot in legacy mode because when it was set to UEFI, i was not able to get the windows installation started. It was after i disabled the secure boot and set to Legacy, and used some Diskpart command line options at windows installation screen, that I was able to get the installation started.
I did not try with windows10 installation media because I think my laptop will throw the same error message because i had tried using a rescue kit (Paragon rescue kit) but i got the same error message "An operating system was not found"
I recently reinstalled windows 8 with help from Microsoft. Faced lots of issues but finally was able to find the solution myself. I assume you have created a USB bootable media and are installing from it. Do post exact steps you have followed and the picture of the error and I will try to hep. Mind you, I did not install Windows 10 but Windows 8 but there is not much different in terms of installation process.

Is your bootable USB FAT32 formatted and using the GPT partition scheme for UEFI BIOS.
Is Secure Boot Enabled in your systems UEFI setup?
Have you tried with Windows 10 Installation Media?

That is setup for a UEFI BIOS... and will not show up with a Legacy Boot.
