Well (looking rather embarassed) I commercially support NT and UNIX for a large computer firm and know NT quite well. How to boot other OS's on a disk other than the one NT is on by copying the boot sector of the disk to a file and referencing it in Windows NT boot.ini does not seem to work unless the other OS's boot partition resides on the same disk as NT. Mine doesn't. I tried anyway, and my system will not boot. I attempted to put a standard (no prompt) boot loader on disk1 (or disk2) and it didn't work either. I was using the /stand/sysintall utility. I managed to get my system booting by using the FreeBSD boot disk and entering 1:sd(1,a)/kernel at the floppy boot prompt. I guess what I really want to do is to install a boot loader on disk0 that does exactly what I manually entered so that the NT boot loader is not displayed. At this time I should be able to copy the boot sector from drive 0 and copy it to a file, then restore the original boot sector of disk0 and reference the file I just created in Windows NT boot.ini. Is this warped thinking? I have looked at all the FAQ's I can and done searches on the mailing list archives and was able to find very detailed instructions and theory on how to boot FreeBSD from the NT boot loader if FreeBSD is on the same disk as NT. I also do not trust sysinstall to do the right thing every time. There must be a manual (configurable) way to install a boot loader explicitly telling it which drive to load the kernel from, but I just cannot find it. In my mind, my solution should be simple, but finding documentation seems to be my biggest problem.
