Warning !!!! Using Lilo is dangerous !! some computer can't even boot up after installing Lilo. This is becox yo DOS partition is over the 1023 cylinder...
If this problem happened, used your windows startup disk (you can make it using control panel ---> add/remove program) and boot from A:
type this :

fdisk /mbr
fdisk

Now u r inside fdisk, go to option number 2 and set the active partition back to yo old DOS partition..

Using loadlin.exe is eaiser. After linux linux was installed, make a linux boot disk using the disk image in your distribution CD, then go into your linux partition and look carefully at /etc/lilo.conf
You should be able to see a line like this :

image=

this is where your Linux kernel file are located. Copy it to your dos partition in a directory together with loadlin.exe
next time, if u wanna go to linux, just change directory to that directory and type this :

loadlin vmlinuz (if vmlinux is the name of the kernel file).
