Here is the BOOT.INI [boot Loader] Timeout=5 Default=C:\$WIN_NT$.~BT\BOOTSECT.DAT [Operating Systems] C:\ = "Previous Operating System on C:" C:\$WIN_NT$.~BT\BOOTSECT.DAT = "Windows XP Installation/Upgrade" Due to GRLDR replacing NTLDR (which I guess is backed up as $LDR$ 255KB) choice 1 runs AUTOEXEC.BAT which runs SMARTDRV and then WINNT Choice 2 is the regular WinXP installer Hitting CTRL-C breaks the batch file giving a working DOS prompt I can easily edit AUTOEXEC.BAT to give me that choice and run a CD-ROM loader from Win98SE, etc. There is no MENU.LST While I do see the utility you mention, I really don't want to undo this effort If I want that, I will create the ISO image and run from a 320GB USB external as described Obviously ilko_t knows how to get the GUI to start after reboot Everything must be there, somewhere, in either $WIN_NT$.~BT or $WIN_NT$ .~LS to start the GUI
