Hi all,

Sorry for the noob question. I have downloaded the .ISO of SLED SP2 and had it copied to a USB drive both uncompressed and via an ISO to USB program. However the Dell won't boot from the USB. In the BIOS option I have secure boot turned off but the only boot device option that appears is "Windows Boot Manager" I can see the light on the USB drive flashing during start up but it goes straight to load Windows 10.

I've read about other people successfully installing SLED on this laptop but for the life of me, I can't get it to work

Any help will be appreciated.

Many thanks.
