The laptop does not see the USB flash drive in bios mode?

Question

Samsung

Good time
There is a bootable flash drive with ubuntu 14
There is a samsung laptop (mother / bios - attached a screen)
The flash drive is 100% working, since we check it on the PC HERE - the bios sees the flash drive, and calmly boots from it if necessary
But the laptop - not in any he does not see the flash drive and that's it ... (in the BIOS)
How can I check - what's the problem?
On the notepad, the usb ports are normal - since after the system boots, the flash drive is visible, it reads / writes perfectly
