NOVATECH LAPTOP Model N250WU

I want to carry out a clean install of my Laptop. What stopping me is how to change the boot order, so that my laptop boots from Cd.

Does anyone know how I can select a cd, please?

If laptop is currently set in UEFI mode the CD Option will not work unless it detects UEFI Bootable Media. Old legacy BIOS show device boot order. UEFI BIOS show detected bootable media.
Make sure install media is in the drive and restart the system. during initial post you can press F7 key to bring up boot menu. You should then be able to choose DVD option for boot. You should get a prompt on screen from DVD to press a key to continue DVD Boot. If you miss that it will revert back to booting from HDD.
