i m trying to install ubuntu on Dell Inspiron 15 using USB flash drive using USSB installer. But in booting sequence there are only two boot options. Legacy boot and UEFI boot mode. Can anyone tell me that how can i set the first boot device = USB flash drive.???

You need to reformat the USB and put Ubuntu on it. When booting, you'll have to press a certain key to bring up the BIOS. There should be a menu that allows you to change boot order.

Check whether the USB Boot option is not forbidden in BIOS menu. Enter it in the menu with pressing F2.
