plpbt-5.0.14 cd does not recognize usb

[lmart]

BIOS does not support USB boot. Using plpbt-5.0.14 cd to boot usb. However, usb not recognized.

Tried it on another laptop, it recognized the usb but hung.

What can I do (step-by-step) to help you help me?

which os do you want to boot from usb?

Thanks @Elmar for replying.

The usb stick has Yumi (http://www.pendrivelinux.com/yumi-multiboot-usb-creator/) to boot SliTaz and PeppermintOS3.

FYI, the usb boots on other laptops. Tried the plpbt-5.0.14 cd on another laptop. It recognizes the usb, tries 2 ECHI ports then hangs.
