Start install by restart, and immediately press and hold the Option key to access Startup Manager.

Intel-based Macs support starting from an external USB storage device's volume that:

Has been formatted with a GUID partition type
Contains an installation of Mac OS X 10.4.5 or later, or Mac OS X 10.5 or later, which is compatible with (or shipped with) the Mac that the USB device is connected to. Note: You should not use a version of Mac OS X that is earlier ("older") than the version your Mac shipped with.
To start from a USB storage device that meets the above requirements, connect the device, then select it in Startup Disk preferences. Or, connect the device, restart, and immediately press and hold the Option key to access Startup Manager.

Generally speaking a Mac won't boot from a system older than it shipped with. If the version of Lion on your flash drive is older than whatever system your Mac shipped with, it likely won't be able to boot from it.

Do you have as second Mac available so you can use Target Disk Mode?
