Hmmm, it won't be easy.

I thought you were familiar (besides the flyakite guide) with the way CDshell works, and more generally XP setup works.
If you are looking for a full tutorial like the flyakite one, I don't think that there is one.
You need to read the grub4dos guide.
And browse/search the grub4dos forum to "get the hang of it".
Then, "translate" your current CD/DVD to grub4dos way of working. (guessing that this should be easier than adding grldr to CDSHELL)
Basically, you should get latest UBCD, here:
http://www.ultimatebootcd.com/forums/viewtopic.php?t=1786Prepare a menu.lst with the various options, a typical entry for an install or PE (when booted from CD) is:
CODE
title Install XP PRO
find --set-root /I386/SETUPLDR.BIN
chainloader /I386/SETUPLDR.BIN
Then add to menu.lst the suggested entry for UBCD.
Be aware that grub4dos is CaSe SeNsItiVe.
Then, without changing the source for your "flyakite" CD/DVD (except adding the menu.lst, grldr and the UBCD .iso) , build a new one with grldr as no-emulation bootsector.
Suitable .cmd can be found here:
http://www.911cd.net/forums//index.php?sho...18045&st=25Another option would be to chain from CDSHELL a floppy image .ima containing grldr and menu.lst, or a plain DOS one with grub.exe and menu.lst.
I am wondering now

if this is a bit "too advanced" for your current knowledge of the matter (NO offence intended

).
Let me know if you are willing to invest some time on the project, I can try and help you, but you will have to do most of the work/studying.
It's possible that some other member can come out with another, simpler idea for UBCD....
