Nothing is deleting in folder i386... With the same unattended CD XP PRO: 1) When I boot with the CD, many drivers are loading then the install look after previous versions installed then ask me to suppress the partition or create a new, etc... 2) On a floppy disk, i create a file the the name "winnt.sif" with a null size. I put this floppy disk in the floppy drive. I boot with the exactly same CD of the point 1. Like in point 1, many drivers are loading then i obtain a window in French: "Installation of Windows XP Pro Welcome ! For install Windows XP now, press Enter key. For repare ou recover an installation of Windows XP, press "R" key. For quit the program of installation without install Windows XP, press F3 key." Thus, with this window i can use the recovery console. If i press Enter key, the next window is the license window, then after press the F8 key, the install software look after previous versions installed... So, i think that the solution with the runoncex.cmd is not good... Perhaps, I am mistaken...
