linux boot troubles

[Ming Hsu <mhsu@u.arizona.edu>]

Hi all, have some problems with Linux boot up.  It all started when I was
having major problems in Windows and had to reinstall Windows.  Afterwards,
windows kind of took over lilo and wouldn't show the lilo prompt after I
hold down the <shift> key anymore.  This has happened before, and I would
just boot Linux off of a disk and run lilo again.  

But this time the disk doesn't work for some reason.  It would start and
say: "boot:".  After I type in "linux" and hit enter, it gives me a "boot
failure" message.  

What is going on?  Do I have a bad boot disk or something?  


Thanks in advance.
