Pavilion 15 Notebook
Microsoft Windows 8.1 (64-bit)

I am trying to restore an  HP Pavilion 15 Notebook(2014 vintage) which was running Windows 8.1 before a disk head crash, which required me to replace the internal HDD. When I try to re-install Windows from a set of 3 Windows 8 recovery media using an external DVD/CD drive (the internal one having died long ago) I do not see an option in Boot Manager to boot from a USB CD/DVD ROM even though I have changed the UEFI Boot order to have the USB CD/DVD ROM Drive option at the head of the list, and CD-ROM Boot is enabled in the Boot Options screen of BIOS (or rather InsydeH20 Setup Utility). The  only options are OS Boot Manager and Boot from EFI File. There is a legacy boot order which has the USB CD/DVD ROM drive at the end of the list but this is greyed out. How can I get the machine to boot from an external USB CD/DVD ROM drive?

Please disable the Secure Boot and Enable the Legacy Boot in BIOS. Then retry the installation

Tried enabling Legacy Boot and disabling Secure Boot as suggested and moving USB CD/DVD ROM Drive to the top of the Legacy Boot Order list but the option to boot from USB DVD/CD ROM Drive did not appear when powering on repeatedly clicking F9. Options are OS Boot Manager, Boot from EFI file, and Notebook Hard Drive,
