i made a multiboot cd with this guide : http://flyakite.msfn.org/
all works great expect this error :

hmm... weird. does formatting with windows 98 yield similar results???

well, you can go with the flow and try out this test...

boot windows xp "original" single cd via vmware and try formatting there and see if it works... try it out with windows 98 boot disk also just to be sure...

i using Virtual PC 2007
and when i use orginal cd its work fine
but when i use my multiboot
so its give this error

i made the multi boot dvd referring to flyakites tutorial too man but mine works fine...

your boot and your hex editing tricks are working fine so i guess theres some problem with the setup files in the SETUP directory...

open the iso with magiciso and overwrite the XP setup files in "AIO-DVD\SETUP\XP\" once again.

mybe its becuase i use nLited windows ? (for all 3 windowses i have ther)
but when i use one of the nliteed windows whitout the multi boot every one work fine

id recommend you keep it simple before you tweak around with nlite.

theres cdshell menu formatting... autoruns and other such cleans ups you'll find interesting but for now get the multi boot working by keeping it simple. thats what i did before i experimented...

i have in my multiboot
a full xp untouched FULL
and its give me the same prob

how many OS do you have in you "multi-boot"? have you tried other NT based OS like 2000, 2003?

anyways, the files to edit are...

this is what i have :
ROOT\setup\XP1(nLited)
ROOT\setup\XP2(nLited)
ROOT\setup\FullXP
ROOT\BOOT\(cdshell)
ROOT\PRO1
ROOT\PRO2
ROOT\PRO3
ROOT\PRO1.DAT
ROOT\PRO2.DAT
ROOT\PRO3.DAT
ROOT\WIN51
ROOT\WIN51IP
ROOT\WIN51IP.SP2

in all of tham i edited
those 3 files
\pro1.dat
\pro1\setupldr.bin
\pro1\txtsetup.sif

the boot to any of the systems is fine
i can choose were to install
but when its start to format driver C
its give me this error ^

the only thing i can think of now is to multi boot 2000 or 2003 and check if it works... if it doesn't then theres surely something wrong your doing with the tutorial.

and if its work so wer the problem ?

well... if the "flyakite" tutorial works on 2000 and 2003 then it should DEFINITELY work on windows xp... if it doesn't then get a new windows xp cd
