I am following these steps but I get a disk error while booting from USB flash: 1. copype.cmd x86 c:\winpe_x86 2. Format UFD as FAT32 on a Vista machine 3. xcopy c:\winpe_x86\iso\*.* /s /e /f e:\ (e: flash drive) 4. bootsect /nt60 e:\ If I take this USB flash and boot a machine I get "disk error". What am I doing wrong? Thanks
