I'm still an extreme newbie so check this with someone who knows thier stuff.

Search this site for "dual boot".

Hi,

i use dual boot too.
This are my settings:

Code:
$ cat /etc/lilo.conf
lba32
boot=/dev/hda
root=/dev/hda2
install=/boot/boot-menu.b
map=/boot/map
prompt
timeout=100
vga=normal
default=Linux
 
image=/vmlinuz
        label=Linux
        read-only
 
image=/vmlinuz.old
        label=LinuxOLD
        read-only
        optional
 
# If you have another OS on this machine to boot, you can uncomment the
# following lines, changing the device name on the `other' line to
# where your other OS' partition is.
#
# other=/dev/hda4
#      label=HURD
#      restricted
#      alias=3

other=/dev/hda1
  label="WinNT(hda1)"
 
other=/dev/hda8
  label="Windows(hda8)"
You have to edit this file.
look at
Code:
$ man lilo
and
Code:
$ man lilo.conf

Install Windows first, then Linux.

well i have xp corp on hdb1 and i have another partition for redhat thats hdb2 and a stuff drive for stuff..

i installed xp and then redhat before and it messed everything up.. it said grub is corrupted..
if i do that now how do i fix it?

can someone that has redhat and xp post me there grub.cfg file?
or should i use lilo ?

Grub is just fine. I recommend using programs on windows(Partition Magic is the best IMO) to rearrange your HD partitioning. Don't let it format the newly created linux partition though(have red hat do this). Since your grub file is on your linux partition and you can't even get to the grub boot screen, use a boot disk(red hat can create this from the CD) and then mount your linux(from what I read, you have it on hdb1) partition and alter your grub. Please be more specific on the error that you are getting.

Make sure your /boot partition and Windows C: are located within the first 1023 cylinders.

A sample config looks like this:

Code:
  Device          Start    End    contents 
/dev/sda1            1        99    Linux /boot
/dev/sda2          100      1023  windows c:
/dev/sda5          1024      2201    Linux /
/dev/sda6          2202      2400    Linux swap
/dev/sda7          2401      4000  windows d:
according to the howtos, you have to dd the linux boot sector to an image file
and tell windows' boot.ini where to find it. lilo and grub might also write such
an image file.

One simple alternative to dual boot I did for friends is to make a linux boot floppy.
If they wanted to start Windows, remove the floppy while booting,
if they wanted to start linux, insert it.
