My troubles installing LINUX

[Jerry Feldman]

NT and Windows will destroy LILO when you install. 
Before installing Windows9X or Windows NT boot from a DOS diskette and run 
fdisk /MBR to clean the master boot record. Install Windows, then boot 
Linux from your resue floppy. Then, the simplest way to reset lilo is just 
issue the command (as root); /sbin/lilo or from YaST.
