Getting a Dell Inspiron 5547 to boot of bootable USB

post #1 of 3
Thread Starter 
So I have a bootable Win 7 USB that I can setup in the BIOS and succesfully boot on both my desktop and Toshiba laptop. However I am trying to use it on my Dell Inspiron 5547 and it is not being recognized at all.


I actually called dell a few weeks back to get them to provide once that would allow me to reinstall the OS on the laptop as there proprietary authentication is hardcoded into the hardware. I explained to them multiple times that I needed a USB key as this computer does not have a disk drive (which they should have been able to see from the model number provided in the first place). I ended up receiving a DVD in the mail...

So I purchased Win 7 professional but now I can't get the laptop to recognize the USB to boot off of. This is what I see when going to select options to boot off of. I have tried the USB in all three ports on the laptop and again this bootable drive works fine on other systems.

Look in the BIOS- is there anything you can change there? You might have to enable USB booting (or something similarly worded), you might have to disable Secure Boot, you might have to change the boot order, you might have to change it from UEFI to Legacy or vice versa on the boot method.

It was the fact that legacy boot needed to be enabled. Thanks for the help!
