OK I'll try change CDIMAGE.EXE... And maybe I should explain what I tryed to do... I've been tryed to make ISO using nLite and original (untoutch) sources (I found topic where somebody has problem with making ISO, when sources are on different partition then nLite - It doesn't make any difference), i've tested ISO on VMWARE and it doesnt work (the same happend after burning ISO on CD it)... after that I've tryied to make ISO and replace booting image from original WinXP CD - still with no effect... every time just after "Press any key to boot from CD..." computer reboots... I'll try to make ISO after change the iso engine, but if it still won't work i belive that is something wrong with rebuiding files...
