How to let my Dell laptop boot from USB flash?

Thanks for the insights.

Did you set/change the BIOS/UEFI password?

You’ll have to connect the laptop to the internet before logging in and then log in using the latest password and then change the password.

That may help.



This usually happens when you set/change the BIOS/UEFI password.

You will have to connect to the internet without logging in to your PC.

Then log in using the latest password.

Then try setting/changing the new password.


Many people neglected to change the first stage of the computer to USB, so it caused the boot to fail.
