Ok, I finally made it work. Instead of creating a new boot file (ex: erdc.dat), i used the bootsect.bin that came with ErdCommander 2003 and i replaced the i386 value by my erd folder. That's one good thing! But, now i have the same problem discussed above. And i'm having another one saying that some hives of the installation specified are missing or corrupted (system, software, sam, security). I'm gonne work on this and I will tell you if i get any answer that could help. Later, Magellan456
