The simplest thing I've found is to change your lilo.conf so it
writes the MBR of your floopy drive instead of your hard disk.
THen you can boot from floppy before you install Windows to make
sure it works. And because floppies are cheap and dismountable,
you can have as many MBR's as you want while you're trying out changes
to lilo.conf. I make sure I have at least two for every serious
boot configuration. Floppies do occasionally die.
Then install Windows, while your lilo boot floppies are safe on a shelf
Then you'll still be able to boot Linux from floppies, reconfigure lilo
to include Windows, and debug your lilo.conf using *different* boot
floppies. ONly when you have it right do you write another MBR to your hard disk.
And by the way, I've discovered Linux is a very useful tool when installing
Windows. Frequently it asks you to reboot during installation.
Occasionally, when it asks be to do so, I reboot to Linux instead of
Windows, and use the occasion to make a full backup of the WIndows partition
being installed. Then I reboot to WIndows as requested.
I've had enough trouble with Widows crashing during installation
that restoring a partly installed WIndows from backup has been a real
