Is there a way i can burn a bootloader with a sanguino 1.3a ...

Is there a way to burn a bootloader to a rambo 1.2g using the sanguinololu 1.3a as a isp?

can i connect the icsp of the two boards together or something like that?

Yes

You just install ArduinoISP onto your sanguinololu, then find out wich pins are required (that will be the tricky part)

scetch says its uses pins: and to me it looks like these are the following

// pin name: on SL
// slave reset: 10: z-direction
// MOSI: 11: z-step
// MISO: 12: PB4 on io header (nb on some boards this is miss labled as PWM d12)
// SCK: 13: MOSI on ISP header

Thanks for the reply i attached a thing can you tell me if you think thats right or how to fix it. pretty new to this and don't want to fry my board

I emailed the place where i got the board to ask if it had a bootloader and they said they don't know and once they run out of stock they wont carry them anymore due to the technical questions they cant answer.

Looks good to me, but bare in mind I havent actuly done this, just working on how it should work.

I think you have to use the corresponding SS/MOSI/MISO/SS pins of the Sanguinulolu instead of using the same pin numbers, as is done on your drawing.
These would be pins 12/13/14/15, which are all on the Sanguinulolu extension headers.

Here is the hookup of my spare Sanguinulolu with which I succeeded to burn the bootloader of a Nano, using the unmodified ArduinoISP sketch:
