Will not boot from original Windows XP Home Edition (with Service Pack 1) CD.
If you can describe the "problem" to boot the Windows XP CD, maybe someone can give you some tip or direction. There are many several possible reasons for it, from a bad CD, the optical drive itself, BIOS problems, power (battery alone against AC power), HDD problems...
Have you tried testing the "bootability" of the XP CD using other computer / optical drive? Can you try a USB drive with XP install / repair?

Some tips to correctly burn the optical media: http://wiki.ultimatebootcd.com/index.php?title=Tutorials:Burning_UBCD_to_Optical_Disc
To burn the optical media, try CD-RW or CD+RW (re-write CD, not just +R -R, and not DVD) using 4x or 8x (and not less nor more speed).
When you say you cannot access any other menu of UBCD, what do you mean? The cursor keys won't work? Try changing the "Fn" key, and/or the "num lock" key, and trying the "normal" cursor keys and the "numerical pad" cursor keys. An alternative would be to try an external keyboard.
