so here is my problem. I am trying to install ubuntu from usb (CD drive is dead) on benq joybook a52e laptop. But the problem is that usb drive larger than 256mb can not be recognized as bootable device, or I just don't know how to set it up. Here is a list of boot options in bios:
hdd
usb key
usb fdd
network

So when i plug 256 mb Transcend 120MB JetFlash 110 USB 2.0 Thumb Drive it is seen in bios, but I can't make bootable 14.01 installation version on that. And the usb's i have are 4gb and 16gb that are not recognized in bios (i have no idea why, maybe because it is old laptop?).

I have tried to make a smaller partition in partitioning software, and it did not work. I have also tried different partition formats (fat, fat32) also didn't work.

So can someone help me how to install it properly, and yes I would like 12.xx or later version of Ubuntu on that machine.
