Well, I don't mind if the drive letter for Windows is changed .I have 5 partitions on two harddrives. Windows on the C: partition of one HD, and the partition I want to install to is H: (which is on the other drive). I want it to be adual-boot system, because I don't want to mess up my system trying something new. I'll tell you what I've done so far: I've got an USB with dos boot files and the folder I386 on it. Autoexec.bat tells to xcopy I386 to drive D:. If I now start the installation (typing D:\I386\winnt.exe) it will start copying files. It puts the folder $WIN_NT$.~LS on the D: drive, while the rest of the files (ntldr, boot.ini and so on) and the folder $WIN_NT$.~BT is placed on the stick. When the computer reboots (with the stick still in) the installation contunues loading files until a STOP 0X0000007B comes up. I guess this is because the USB drivers is reset or something? Well, I like experimenting a bit .
