Post subject:  Booting Linux from XP's Boot.ini

I've written up a small linux article for myself, that involves booting a
linux partition on a second hd, from the 1st hd's XP boot.ini .

Basicly it involves coping the linux's first hd block as a bootable MBR
file to be used as a windows boot.ini entry.

ie...

dd if=/dev/hdc1 bs=512 count=1 of=linux.mbr
copy /save/linux.mbr c:/
c:linux.mbr="linux boot partition"

While this works on an installed linux, if you change the linux kernel later,
you must also re-copy the mbr back into windows again.

Does anyone else know of a linux bootable procedure that does not step
on my windows MBR, I had to use FIXBOOT once already.

Continuing saga on Linux Loaders and XP...

I finally found a linux distro (DSL) that would install a LILO
on a 2nd hd so I could use it to boot a windows XP, by setting
the bios to start at the 2nd, and then the 1st hd.

Unforturnally (I think), the previous DD method now fails (go fig).

The current flavors of linux I'm playing with:

- DSL (damm small linux), a livecd mini linux
- PCLinuxOS, also a mini live cd, but does onlin installs
- Puppy, also a mini live cd with an online repository

All the above will act as a LiveCD, and allows hd installing
once you're satisfied that you like it.

Oh well, back to getting XP to booting a Lilo...

And what flavor of Linux do you run ?

I'm not sure how to do this anymore since I've been using Linux exclusively for a couple years now and have no use for dual boot. I believe it involves making Linux have it's own boot partition and own boot loader.

This example uses grub and assumes the windows install is on hd0,5 which means the first harddrive detected, fourth partition. Partitions as assumed by grub atleast are numbered 0-x, 0 being the first and x being how many partitions you have.

title=Windows XP
rootnoverify (hd0,5)
makeactive
chainloader +1

hope I've helped atleast a little.

PS, I'm using Gentoo Linux

I'm dualbooting XP and FC5, using Grub. I can get back and post my grub config if anyone's interested. I'm in XP now though so it'll have to be tomorrow or so.

Would never dual boot linux and windows on the same machine myself, tho I know thats not possible for every one.

I'm doing what munsen said. I have Windows installed on my primary IDE drive (/dev/hda) and Linux on my primary SATA drive (/dev/sda), with grub installed on the SATA drive. Here's my current grub.conf.

Code:
# Which listing to boot as default. 0 is the first, 1 the second etc.
default 0
# How many seconds to wait before the default listing is booted.
timeout 30
# Nice, fat splash-image to spice things up :)
# Comment out if you don't have a graphics card installed
splashimage=(hd1,0)/boot/grub/splash.xpm.gz

title=Gentoo Linux 2.6.15-r7
# Partition where the kernel image (or operating system)  is located
root (hd1,0)
kernel /boot/kernel-2.6.15-gentoo-r7 root=/dev/sda3

title=Gentoo Linux 2.6.15-r5
# Partition where the kernel image (or operating system)  is located
root (hd1,0)
kernel /boot/kernel-2.6.15-gentoo-r5 root=/dev/sda3

# The next four lines are only if you dualboot with a Windows system.
# In this case, Windows is hosted on /dev/hda1
title=Windows XP
rootnoverify (hd0,0)
makeactive
chainloader +1
