Unable to boot Windows 10 from USB flash on Dell Inspiron 15SE 7520
Hello,
I have a Dell Inspiron 15inch 7520 with A11 version of BIOS, latest from dell.com. I decided to reinstall Windows 10 from USB stick which is formatted to FAT32 and is bootable. The issue is that I am unable to choose USB boot from the menu when pressing F12. I tried under both UEFI secure:on and Legacy boots, but it does not want to boot windows at all. When the usb stivk is plugged in it stalls at the dell logo. When it is not it nornally runs my already installed windows 10. Under UEFI boot settings there is only 1 option - the windows itself. Under legacy boot options theres only HDD and Network (when switched to legacy boot option). I have both tried Microsoft media creation tool and Rufus to create the flash bootable. It is the same with both - pc stuck at logo screen unable to boot the installation. Please help.
Kind regards,
Raycho

You are using a x64 version of Windows 10? When you made the Flash Drive from the .iso you mounted the file and copied over the contents?
You have the flash drive plugged in prior to booting or restarting?
Tried other USB ports?

With secure boot On or Off it goes into an infinite loop of restarts at the Dell Logo. The iso image is from Media Creation tool and it still cannot boot.

Used Media Creation Tool which makes the windows.iso which must be x64 version yes. Flash drive is plugged in. Thats why it goes inti an infinite restart loop. If I unplug it I get this message: System doesn't have any USB boot option. Please select other boot option in boot Manager menu.
