Copy the file from the diskette to C:\\bootsect.lnx. I don't tell you how to do that.
What lilo.conf is for linux is c:\\boot.ini for Windows NT. Remove the, system- and the read-only-attribute before you can modify it with:
C:\attrib -s -r c:\boot.ini
Now change the file boot.ini with an editor, notepad for example, as follows:
[boot loader] timeout=30 default=multi(0)disk(0)rdisk(0)partition(1)\WINNT [operating systems] multi(0)disk(0)rdisk(0)partition(1)\WINNT="Windows NT Workstation ... multi(0)disk(0)rdisk(0)partition(1)\WINNT="Windows NT Workstation ... C:\BOOTSECT.LNX="Linux"
Only the last line has been added in this example. Restore the attributes after you have saved boot.ini with:
C:\attrib +s +r c:\boot.ini
After a shutdown of your Windows NT and a restart your should see the following:
OS Loader V4.00 Please select the operating system to start: Windows NT Workstation Version 4.0 Windows NT Workstation Version 4.0 [VGA mode] Linux Select Linux and see LILO loading zImage ....
