I've got a WINPE 2.0 BootCD (which I built from the WAIK) which does the following: 1. loads up 2. calls diskpart from starnet.cmd 3 imagex applys a syspreped image of xp sp2 4 reboot Diskpart instructions: select disk 0 clean create part primary size=9500 select part 1 active format fs=ntfs label="SYSTEM" quick assign letter=c exit Now the cd has been used on a brand new HP DC7800 which is preconfigured as follows: xp pro xp2 sp2 2 partition / 65gb + 10gb / c: and d: It boots the cd fine, diskparts and then copies the image down. On Reboot the machine says "BOOTMGR is missing". If we boot from the CD again and run through the diskpart, reimage and then reboot it loads as expected. Whats going wrong on the first pass, why is BOOTMGR missing and why is it fixed when we re do the process? I've used this same process on other machines with no problem. Any help appreciated.
