a Linux Boot
Unofficial Updated Guide to Linux BootDisk Creation and Use by Mark Rais
If you have not yet installed
Linux, but for some reason prefer to manually create a bootdisk rather
than let the installation make it for you then please use the rawrite
program included on your Linux CD-ROM under the dosutils subdirectory.
For general RedHat Linux
Installation Help please go to our Installation
Create Your Emergency
Linux Boot Disk
it or not you're going to need a floppy disk to do this so please
make sure you have one handy!
2. Load up Linux
and make sure you are logged in as root or have enough privileges
to run system commands.
3. Check which
Kernel you are running by typing exactly this at the command prompt:
This should give you a directory item with the exact kernel such as: 2.4.2-2
4. Now insert
your floppy diskette into the A: or floppy drive. In Linux the a:
drive is also known as fd0
(that's with zero not an 'o')
5. At the prompt
please type: mkbootdisk --device /dev/fd0 x.x.x-x
replace the x.x.x-x with the kernel info you got from the step 3
6. You should
have an emergency boot disk within about 1 minute. All previous data
on the floppy will obviously be erased.
7. Now you may
use this floppy to boot in emergency situations! Enjoy!!!
What if the mkbootdisk utility isnt available?
On some versions of Linux you can instead create a boot disk by typing this command at the Linux prompt:
dd if=/mnt/cdrom/images/cdrom.img of=/dev/fd0
Be sure that you have put your Linux CD into the CD-ROM drive and a floppy diskette into the floppy drive, and that both
of these have been properly mounted. Then run the command!
