unable to dual boot with new windows partition

I installed Windows on a new partition for gaming. It erased the bootloader of course, and so I reinstalled Lilo and booted back into Slackware. Everything's peachy at this point.

Then I decided I want to play a game, so I rebooted and start the Windows partition. It just sat there saying Loading Windows. So I restarted again and booted into Slackware (which boots just like it should) so I could run lilo because I assumed something messed up. It gives me the following error:

Fatal: First sector of /dev/sda2 doesn't have a valid boot signature
My partition table looks like this (output from cfdisk):

       Name                  Flags                Part Type           FS Type                       [Label]                    Size (MB)
       sda1                                        Primary            ext4                                                     115346.51           *
       sda2                  Boot                  Primary            HPFS/NTFS/exFAT                                          372650.28           *
                                                   Pri/Log            Free Space                                                    0.86           *
       sda3                                        Primary            swap                                                      12110.23           *
sda1 is Slackware, and sda2 is Windows. My /home is a separate harddrive (sdb1).

I tried toggling the boot flag on the Windows partition, but it does the same thing whether its shown as bootable or not.

Before I reinstalled Lilo, the Windows bootloader would load it just fine.

my lilo.conf:
# LILO configuration file
# generated by 'liloconfig'
# Start LILO global section
lba32 # Allow booting past 1024th cylinder with a recent BIOS
# Append any additional kernel parameters:
append=" vt.default_utf8=1"
boot = /dev/sda

# Boot BMP Image.
# Bitmap in BMP format: 640x480x8
bitmap = /boot/slack.bmp
# Menu colors (foreground, background, shadow, highlighted
# foreground, highlighted background, highlighted shadow):
bmp-colors = 255,0,255,0,255,0
# Location of the option table: location x, location y, number of
# columns, lines per column (max 15), "spill" (this is how many
# entries must be in the first column before the next begins to
# be used. We don't specify it here, as there's just one column.
bmp-table = 60,6,1,16
# Timer location x, timer location y, foreground color,
# background color, shadow color.
bmp-timer = 65,27,0,255

# Standard menu.
# Or, you can comment out the bitmap menu above and
# use a boot message with the standard menu:
#message = /boot/boot_message.txt

# Wait until the timeout to boot (if commented out, boot the
# first entry immediately):
# Timeout before the first entry boots.
# This is given in tenths of a second, so 600 for every minute:
timeout = 1200
# Override dangerous defaults that rewrite the partition table:
# Normal VGA console
vga = normal
# Ask for video mode at boot (time out to normal in 30s)
#vga = ask
# VESA framebuffer console @ 1024x768x64k
# VESA framebuffer console @ 1024x768x32k
# VESA framebuffer console @ 1024x768x256
# VESA framebuffer console @ 800x600x64k
# VESA framebuffer console @ 800x600x32k
# VESA framebuffer console @ 800x600x256
# VESA framebuffer console @ 640x480x64k
# VESA framebuffer console @ 640x480x32k
# VESA framebuffer console @ 640x480x256
# End LILO global section
# Windows bootable partition config begins
other = /dev/sda2
label = Windows
table = /dev/sda
# Windows bootable partition config ends
# Linux bootable partition config begins
image = /boot/vmlinuz
root = /dev/root
label = Linux
# Linux bootable partition config ends
So anyway, this is everything I could think of that could matter. Is there something wrong in any of this that I can fix to be able to properly boot both Slackware and Windows?

thanks for any help!

How I wish I could help, but this one, I only booted Lilo once, years ago, and then learned Grub Legacy.

I suppose if you re-install Lilo again and then into the MBR will it not automatically sense the Windows in sda1 ? the way it is going with installing Grub?

Why not try? I think you have nothing to lose now that Windows booting is lost.

Good luck.

Hope that helps a little. Hope others are coming who know Lilo better.
