Sorry, been on holiday!
Try remove splash and quiet from the cmdline and append debug. That
might show where we are getting stuck.
With new machines, I suspect UEFI or "secure boot" (aka run only
Windows boot because Microsoft are subsidising PCs & Microsoft want to
monopolise this platform) might be causing an issue and it may need
switching back to BIOS "legacy" mode.
Don't be afraid to re-image the USB install disk and also try in other
hardware to sanity test your media & hardware.
If you are a paying customer, let me know how many machines, and if it
is worthwhile I can try source one from Dell.
