How to get my Inspiron 5767 to boot from USB?

Hi Chuckles1066 , you may want to try to change the Boot Mode to Legacy instead of UEFI in your BIOS because you're trying to install Windows 7.

.

Once you've change the boot mode to legacy. Save and exit, go to One Time Boot Menu (F12) during restart, and then try and select your USB.

Thank you for your message.

This system is shipped with Intel Kabylake processor.

This processor supports only Windows 10.

There are only Windows 10 drivers available for this model. No other drivers are tested.

We do not recommend Windows 7 installation.

For my reference, please click on my Dell username & send a private message with the service tag, registered name & email address.

ejn63: To clarify, Classic Shell will NOT make the Windows 10 interface exactly like Windows 7 or anything else. All classic shell does is change the start menu to a version very similar to Windows 7. All other aspects of the Windows 10 interface remain Windows 10. The Windows interface consists of a lot more than just the start button and start menu, which is a small fraction of the overall Windows 10 experience. Classic Shell does help mitigate some of the glaringly awful parts of working with Windows 10 but not all of them unfortunately.

Whatever it does - the fact remains -- new hardware means windows 10 -- there is no longer hardware support for anything older.

The fact also remains that it's unhelpful to suggest that Classic Shell will make a PC work like Windows 7 when it will not. With Windows 7 rapidly approaching end of support, it's unwise unless absolutely required to deploy new systems with Windows 7. That said, as an IT provider, there hasn't been a modern system made that I've been unable to install and run Windows 7 on. While Dell or whomever may not provide drivers for all the parts and will not support a system that has been upgraded from Windows 10 to Windows 7, that doesn't mean it's not possible to install it and make it work. That said, it may run in a degraded mode where not all the ancillary hardware works due to lack of driver availability.

Again, I'm not recommending installing Windows 7 on it, and am advising against it, but with knowledge and effort it should be possible.

The degradation extends beyond hardware - Microsoft has blocked updates to 7th and 9th generation Intel and AMD Ryzen platforms -- and while you can -- for now -- hack around that, there's no guarantee the workarounds will work forever.

Windows 7 is rapidly approaching end of life - most businesses run on three year cycles, meaning 7 will go completely dark months before a system purchased in October, 2017 is replaced on its regular cycle.

If you must have Windows 7, there are still supported ways to run it - on Skylake platforms, for now.  Once those go, so will all official support for Windows 7.

The single biggest complaint most new users have is how different the interface in 10 is vs. 7.  Classic Shell DOES remove that complaint, whether or not your opinion of Windows 10 allows you to see that it does.

No, classic shell does not remove that complaint. It's putting lipstick on a pig. It;s still a pig.

You seem to have a clouded view of Windows 10 -- coupled with a very cursory knowledge of what Classic Shell can and does do.  Opinion noted in light of that.
