Question about making a boot disk

ludwig W · 05-06-2003, 02:48 PM

Hi,
I have a boot disk from my first install of RH8 but since then i have a different kernel (2.4.20) and have since deleted the stock 2.4.18-14 kernel that came with RH8. I understand that the boot disk is unique for each kernel.

I'm not sure if there is an easy way to make a boot disk ,but if there is ,perhaps someone could tell me.Otherwise,what I was thinking was that,whenI look at the boot disk that I made on my first RH8 install,I see that there is a initrd.img and a vmlinuz. Could I just copy my version of these files from my /boot directory onto the floppy,overwriting the ones that are there?

It's probably too simplistic,I know.

mkbootdisk <name-of-kernel-image>

do this with a floppy in the drive.

thanks.

no problem.

when I type
mkbootdisk initrd-2.4.20.img

I get:
/lib/modules/initrd-2.4.20.img is not a directory.

What am I doing wrong?

try the full path to the kernel image

take a look at the manpage for it.

check out this thread... worked for him.

could also try the dd command:
4.5 Make a boot disk within Linux.
Open up a terminal cd to the images directory and type dd if=xxxx.img of=/dev/fd0 where xxxx is the name of the image.
Read the README file or INSTALL file for more information.
