MAKING a BOOT FLOPPY


If the GUI-tool for making a boot-floppy fails, there is a simple ( command line ) way to make one, the tools are a bit different depending on the distro you use:
( no need to wipe/format the floppy before you start, it will simply be overwritten anyway )



Mandrake: ( Pre kernel 2.6 ! . . . post kernel 2.6 see Boot/Rescue CD )

CODE
$ su
< password >
# uname -r

( will show you the kernel-version: probably 2.4.21-0.13mdk )

CODE
# mkbootdisk --device /dev/fd0 2.4.21-0.13mdk


And put in a floppy and press enter, That´s all !



RedHat:
The same as Mandrake ( only another kernel version ) but you have to add /sbin:

CODE
# /sbin/mkbootdisk --device /dev/fd0 <kernel version>



Slackware:

CODE
$ su
< password >
# makebootdisk

And a dialog will pop up and make the floppy.



VectorLinux:
Same as Slackware



Debian:
( Also Knoppix HD installed )

CODE
# mkboot -r dev/hda? <kernel-version>

( hda? Is the root partition, replace the ¨?¨ )


NOTE: Always test your boot-floppy after you made it


So, next time you feel like doing some serious work on your system, and things go wrong, you will have a good way to boot even if the MBR gets overwritten. Simply boot from the floppy and restore Lilo or Grub to the MBR:

CODE
$ su
< password >
# /sbin/lilo

or

CODE
# grub-install /dev/hda


Have fun tweaking your Linux box ! ( You can even do a re-install of windows without having to worry about the boot-loader )
