Programming bootloader of a PIC microcontroller

I got a old used picdem board for free from my friend and I have a bootloader to it. It's old one got erased.

I don't have ICD to program the bootloader, is there any way I can program the bootloader using usb or develop something by my own? But the problem is since the bootloader got erased by accident the usb won't be detected when plugged in.

I'm using PIC18F4550 microcontroller

No, you can't program the bootloader over USB, because the bootloader contains the USB code. A blank PIC does not understand USB. It is not even running it's oscillator. Get an iCP01 or an ICD.
