Please, can anybody spend a bit of time to help me with the WinSetupFromUSB operation? Apparently, it seems to be a very very nice combined utility. I tried it several times to get a bootable flash drive with XP PE, but couldn't succeed, though. Could anybody explain, at what stage and how should I get at least 2 or more files to boot a flash drive with WinXP on it? Say, my BIOS waits for NTLDR and NTDETECT.COM and probably some others. But I can't see WinSetupFromUSB provides them all, alas. WinSetupFromUSB consists of 3 parts as seen from its interface. Which one of them should provide the booting files and at which stage? I also prepared my flash drive as indicated in advance: Formatting it FAT32 or NTFS, activating beforehand. Although, I still cannot see NTLDR and NTDETECT.COM and probably some others. Or should they be borrowed from anywhere else? Please, help. THX.
