How do i do a clean install of window 10 using dvd boot up

hi everyone, I need help with learning how to do a clean install of windows 10, I know that if I insert the installation media I made by using the windows 10 media creation tool, I'm going to have to change the boot order on my HP notebook,and i will have to wipe all allocated partitions except the 1 in allocated partition on the disk, I have a cracked touchscreen on my pc and will likely send it in for repair tomorrow, and they may install the default OS using the original recovery disks I have to send in with this PC, if they do use the recovery discs and restore it to factory, I will likely start from scratch, and maybe even if They don't, from what I see on the bios there are two options for disabling:

1. Legacy Support mode(disabled)
2.Secure boot(enabled)

which one do i choose, and how do i change the boot order, also how do i go about doing a clean install, should I insert the disk while the OS is running or change the boot order and boot from the windows10 upgrade/installation disk via internal dvd drive?

With notbooks I suck but I think i can give you heads up

You are talking about USB then you say dvd // it doesnt matter what you use it will all work

Insert dvd or usb boot change boot order then exit the pc will boot again you should see press any key to boot from dvd or cd///
if you have usb in there then it should boot in to it normal and take it from there

no need to be afraid at this point because you have already decided to do a clean install

good luck

thanks for your help,im up and running with a fresh install of windows 10.
