hi! i have a little problem.

i would like to boot as well as install xp using my hard drive. this is my story:

i have a sony vaio picturebook pcg-c1vn, this laptop does not have any optical drives. i had to reinstall windows because it had crashed. this is what i have done but still no good results:
1. install xp using an external usb cdrom (cannot boot because the bios is not updated to boot from a usb)
2. install xp using a pcmcia cf card adapter
3. install using usb flash disk (same reason because i cannot boot from usb)
4. extracted the hard disk, placed it in another laptop and installed xp there instead since laptop 2 (asus degatto) has a cd rom but still unsuccessful since the chipset of the asus degatto has higher specifications as compared to my sony vaio


so my question is this:
since i was able to extract my hard disk i placed it in an enclosure (so its now an external hard drive), i would like to format the hard disk then make it bootable then copy the setup files of the win xp there. so when i return the hard disk to my sony vaio it will boot from there then install xp from the hard disk itself. is that possible? a little help there please. thanks a lot!!!
