If its anything like my Dell then you probably have to hold the F12 key as it boots to get into the 'one time' boot menu. Change to boot from USB and you should be good to go. I found W10 installed very quickly indeed, perhaps 7 or 8 minutes in total with using an SSD.
Mooly, took a look at the BIOS yesterday and it's a bit more involved than I'm accustomed to from my 4 year old Dell XPS 15 laptop. For me at least it wasn't as intuitive and changing the boot order seemed a bit daunting. Changed nothing for the time being. But I'm being told no changes are required and the machine will automatically boot off the thumb drive if the drive is in place and the OS will install pretty much without much input from me.
Hmmm... as I mentioned, UEFI is something I've not got on any of my PC's. You are just going to have to try it and see I think.
I would think is equally applicable to W10,

Hi, Carbo. Did you make a separate factory restore image using Dell Backup and Recovery first, or have you made a complete disk image with a reliable imaging program? That would be the first thing to take care of.
If you used the correct settings in Rufus for the USB flash drive you created and place WIn10 install files on, you should get a boot menu after tapping the F12 key as soon as you power on the laptop and be able to see a list of at least 2 choices to select for boot at the upper part of the displayed info - select the choice that describes your flash drive.
You will indeed need to interact with the initial parts of the install, particularly to delete all of the partitions until nothing but unallocated space remains on your system's disk. THis is all described in the Tutorial you were pointed to.
I enabled Legacy boot and disabled Secure boot. I was able to boot off the USB. That's the good news. The bad news is I have quickly run into an error of some kind when starting the install. I'm seeing a screen that asks "Where do you want to install Windows?" Followed by "We couldn't find any drives". Then I have an option to "load driver". But I don't have or know what driver they are looking for. What did I do wrong?
I'm not sure how you proceed in that case, not without sitting in front of it at any rate. If no one chimes in then its probably worth just asking that as a separate question.
I'll look in tomorrow and see how its going, good luck :)
Does this help perhaps,

Mooly, shortly after posting I found the issue. Needed to correct the boot order in the BIOS, (which I thought I had already done). Partitions are visible and should be smooth sailing from here. Many thanks for all your help.
There would be no reason to enable legacy support - unless you want to install in legacy MBR modeI enabled Legacy boot and disabled Secure boot. I was able to boot off the USB.
