I have installed Red Hat Linux 9.0 with Dual boot LILO.

When I try to boot Win Xp, I get following error:

Loading DOS
Error 0x40
Boot DOS.

How Do I boot my machine with Win XP

Thanks for your help in advance.

Hi You can set the default OS in Lilo to windows.
You just open /etc/lilo.conf file with a text editor(as root) and change the default= line to default=windows.

Error 0x40 is a seek failure.All the list of Lilo error messages says is "media problem.Try booting again". Chances are you didnt install Lilo to the Master Boot Record and XP's not where lilo.conf says it should be.Post your /etc/lilo.conf file here so we can look at it.Also list how many hard drives you have and how they're set up.
When you got to the part during the Redhat installation where you set up the bootloader ,did you choose a bootloader other than the default?I thought Grub was the default for Redhat.I'm sure this can be worked out without reloading any OSs.

It's not exactly the same problem, I don't get the error message. It boots linux fine, but when I try to boot WinXP it just hangs at Loading DOS and blinks a cursor at me forever.

This was originally a redhat installation, I installed WinXP on one 6G hd and had no problems with it. Then I decided to install rh9 and now can't get to WinXP (just for a few programs and stuff that still runs too slow on linux).

The configuration is like this:
# fdisk -l

(I forget why hda8 was Win95/FAT. Think I was trying something out long ago and forgot about it)

I changed from grub to lilo for the bootloader mainly because I was used to lilo from before (used to boot different kernels).

here's /etc/lilo.conf (generated from the installer)
# cat /etc/lilo.conf
prompt
timeout=50
default=linux
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
message=/boot/message
linear

image=/boot/vmlinuz-2.4.20-8
label=linux
initrd=/boot/initrd-2.4.20-8.img
read-only
append="hdd=ide-scsi root=LABEL=/"

other=/dev/hdc1
optional
label=DOS


Any idea how to get them to co-exist without needing a boot disk? (I don't even have the floppy installed on my machine anymore)[code][quote]
