Cannot Install Win10 on older system

So I have an older system that has a BIOS and not a UEFI. The mobo is an Asus P6T Deluxe v2 with an I7 920. Read at some places that they got Win10 installed on this board, but no clear guide on how they did it or if they ran in to any issues during install. Currently it has Win7 Pro installed.

I used Rufus along with the Win10 1903 image and all went fine. When I booted the Win7 system with the thumb in a USB slot I went to the BIOS and selected the USB to boot from. All I get is the installation where it shows the Microsoft flag and that's it. Normally I would see below it the dots that go in a circle and then the installation questions begin. But here just the flag. I left the system like this and came back 8 hours later and still like this. So digging around I saw a part about turning off the vt in the BIOS so I did that, but same thing. I tried different versions of Rufus and still same thing.

Coming here to see what else I can try or what I may have missed.

Thank you

The simple way is goto the media creation tool web page but update and do it that way. If there is a problem it will tell you

@ Samurai - I will try that @dalchina - yes. I already have a recent image as well as backed up all the data. I have a list of programs that I need to re-install once I get Wind10 on it. I was trying to do clean install which I normally do with O/S's, but in this case if the easier way is to do an upgrade then I can do that. I'll read up on the link

Thank you everyone.

Its safer to do the upgrade if your having problems then if required once you know t works you can refresh to et a clean install or do clean install knowing it will work. If you update from 7 it keeps all your files and programs

How were you going to activate the clean install of Windows 10?

OK, so strange things but working now. I read the links and I also remembered that uninstalling the A/V also helped so I did that. I did turn off the VT-d, but still did not work. I kept looking around and I found a note from my archives where this happened to me once with Windows XP. Uninstall the LAN drivers. I did all that at the same time so not sure, but after about 7 reboots it finally worked.
@navyCLDR - I used my Windows 7 license key to activate. Works, I have done 5 system clean installs that had Windows 7 and they are 10's. Entered the key and viola!

Thank you again everyone. Got one more old system to do, but for another time

Use the Media Creation tool to create a bootable USB stick, boot from that then upgrade. That should give you Windows 10 with a digital licence. You can then clean install if you wish once you have that licence.

Check your CPU meets the requirements for 64 bit Windows 10 else you will need to install the 32 bit version.

I had problems booting from a USB stick on my old 2006 PC which I upgraded to Windows 10. I had to boot to a Windows 8 DVD I had, run the DOS command window then run the setup file on the USB drive form there!

I tried to install Windows 10 1809 64 bit on a Dell Dimension 9150. The DVD kept rebooting. When I changed to a 32 bit image it worked. I already had Win7 and 8.1 activated so Win 10 activated.
