partition nightmares

I copied some instructions from the link sent you this morning.
Mount the floppy drive if it's not mounted (assumes /mnt/floppy
exists): mount -t msdos /dev/fd0 /mnt/floppy
Run the following command: dd if=/dev/hda2
of=/mnt/floppy/linux.bin bs=512 count=1
Substitute the path for the if= parameter (the input file) with
the appropriate partition from the previous step. E.g., set if=
to /dev/hda2.
Reboot into Windows
Copy the linux.bin file to C:\
Run notepad and edit C:\boot.ini. Note that C:\boot.ini is a hidden
system file, so it probably won't show up in Windows Explorer. To
edit the file, try: Start->Run and enter: notepad C:\boot.ini. Add
the following line at the end: c:\linux.bin="Linux"
Reboot again. You should be able to pick either Windows or Linux.
Selecting Linux will start GRUB

Thanks Andy,
Sorry I've never done this before so am a bit nervous until I am totally
clear what to do. How do I back up my bootloader? What you are saying
is :
1) backup bootloader (not sure how I do this, just copy /boot?)
2) run fdisk /mbr off a bootable cd
3) reinstall bootloader (how do I do this?)
4) then you are saying I should be able to boot windows or linux again
from grub
I was wondering if you are someone could help fill in the blanks for me.
Thanks again for the help Andy.
cheers,
jim
