How to use Topologilinux's "grubinstall" to dual-boot WinNT/2K/XP and Knoppix
What?
This how-to shows you how to install a special Windows version of GRUB, written by the creators of Topologilinux, to dual-boot Windows 2K/XP (installed on an NTFS-formatted partition) and a hard disk install of Knoppix. (It can also be used to dual-boot any version of Linux, as well as a "poor man's install" of Knoppix.)
Why?
This version of GRUB loads after Windows' existing bootloader, "NT loader" (hereafter abbreviated "NTLDR"). In other words, first you'll get an NTLDR screen asking which OS you want to boot. If you choose Linux, then GRUB comes up. It doesn't change your MBR.
If you install GRUB or LILO when you install Knoppix, there's always the risk that something will go wrong and your Windows partition will be rendered unaccessible. This method greatly reduces that risk, since it doesn't change the existing MBR.
Where to get it?
It can be downloaded from here:
http://hem.passagen.se/svto/tlinux/files
-- get "grubinstall-1.0.zip". Or you can get it by downloading the entire first CD of the Topologilinux 4.0 2-CD set, but the version on hem.passagen.se is newer.
There are some other differences between the two versions, most notably that "ntfsinstall.exe" in the CD version is named "grubinstall.exe" in the newer version, and you don't get an "install.bat" file or a sample "menu.lst" with the newer "grubinstall-1.0.zip" package. This how-to uses the files from the newer "grubinstall-1.0.zip" package, rather than the version on the Topologilinux 4.0 CD.
What are its limitations?
Grubinstall uses a file, "stage1", that needs to be on the same partition as NTLDR. In other words, you have to put it on your "C" drive.
Grubinstall's "stage1" and "stage2" files cannot be on a compressed volume, nor can they be individually compressed by Windows. The most common reason for this version of GRUB not working is that people try to install it on compressed drives.
If you defrag your Windows partition, you have to reinstall this version of GRUB.
It only works on NTFS-formatted partitions (NTFS = "NT File System", the default for Win2K/XP), not FAT32.
You must have Administrator rights to install it.
How to install it?
You should always have a backup before you (re-)partition your drive(s) or install any boot loader.
You need to already know how Linux refers to hard disk partitions, or it's not going to make much sense.
Start by reading the files (install.txt, readme.txt and faq.txt) inside the grubinstall package. Also read the GRUB manual at http://www.gnu.org/software/grub/manual/html_node/ in order to get a sense of how GRUB works and how to write a "menu.lst" file ("menu.lst" is the name of GRUB's configuration file).
What follows is all based on the assumption that your copy of Windows is installed on the first primary partition on the master hard drive (or the only hard drive, if you've only got one) on your primary IDE channel, which is formatted as NTFS. It's known to Windows as your C: drive, to Linux as hda1, and to GRUB as (hd0,0).
You will need to log on to Windows with administrative rights to do this.
Make a directory named "boot" at the root level of your C drive (i.e. C:\boot) and copy the files from grubinstall-1.0.zip to it.
Create a "menu.lst" file in C:\boot that will tell GRUB how to boot Knoppix (see below for examples).
Now you should now have (at least) the files "menu.lst", "stage1", "stage2", and "grubinstall.exe" in C:\boot.
Make a backup of C:\boot.ini. (C:\boot is a good place to store it.)
Unset/clear the "read-only" attribute on C:\boot.ini (you can do this in Windows Explorer by right-clicking on it and selecting "Properties" from the context menu) in order to make it editable. Open it in Notepad by double-clicking on it. Add the line
C:\boot\stage1="Knoppix 3.4"
to the bottom of boot.ini. Save it and reset the "read-only" attribute.
Pull up a command prompt, navigate to the C:\boot directory, and run the following command:
grubinstall -d C:
Reboot your computer. Windows' NTLDR should now give you a boot screen allowing you to choose between Windows and Knoppix. When you choose Knoppix, the GRUB boot screen should come up, and once you make a selection there (or let it default to the first entry), it should boot Knoppix. If it all works as it should, congratulations! You're done.
If it doesn't work as planned, reboot with Ctrl-Alt-Del, boot back into Windows and make sure C:\boot\menu.lst (the GRUB configuration file) is correct. You do not need to rerun grubinstall.exe after you change "menu.lst". (You can also edit your GRUB commands from within GRUB itself, but your changes aren't automatically saved.)
Setting up GRUB's menu.lst:
First, some GRUB terminology. GRUB refers to hard disk partitions as follows:
GRUB Linux equivalent
(hd0,0) /dev/hda1
(hd0,1) /dev/hda2
(hd0,2) /dev/hda3
(hd0,4) /dev/hda5
(hd1,0) /dev/hdb1
(hd1,1) /dev/hdb2
(fd0) /dev/fd0
(cdrom) /dev/cdrom
The parenthases ( ) around the partition names are required.
Lines that start with the pound sign # are comments and are ignored.
Sample menu.lst #1:
Win2K on hda1; Kanotix Bug Hunter 5 (a Knoppix variant)'s / (root) partition on hda2.
Kanotix has 2 kernels (2.4 and 2.6) installed, and GRUB allows you to choose between them.
"hdc" and "hdd" are CD-R drives (thus the "hdc=scsi" and "hdd=scsi" parts).
The "vga=733" line tells Kanotix/Knoppix to use a text-mode resolution of 1024x768. If you don't like that, or if that doesn't work for you, try "vga=normal".

Kernel and miniroot files from the CD are saved in C:\knoppix on the NTFS partition (!)

Final note: All this sounds harder than it really is. Standard disclaimers apply: If this causes your computer to burst into flames, or erases your hard drive, don't come looking for me (or the author of grubinstall).
