Hello, I have been looking around searching and not found anything yet. I probably missed it, but I already can do a bootable lilo cd. But I can't find anything on how to make a bootable grub cd. Could someone either tell me or point me in the direction I need. I already looked at linux-live.org but not what I need. I wanted to make a bootable grub cd.

Is this possible

Thanks

Grub Boot Floppy

Now that site tells you how to make a boot floppy, so instead of doing that to a floppy drive, do it to a file and use that file as a boot image to include when you do a mkisofs.

Thanks for the help, but this seems to want to write to the first and second block of the floppy disk. Can't wirte this to a dir or file. Unless I am missing something here.

Thanks

oh, duh, good point What you need to do is build an image with those two files sandwiched together. I didnt' read the dd statements carefully enough.

I found some place on the web with instructions on how to make a grub boot floppy. Can't remember where though.
Anywho, I used those notes and some notes on making a bootable cdrom from a Windows boot floppy I just used the grub floppy instead and it worked!!

Here are my notes.....

1. Creat the Grub boot floppy

This gives you the boot menu just like it was installed on the hard drive.

fdformat /dev/fd0
mke2fs –m 0 /dev/fd0
mount -t ext2 /dev/fd0 /mnt/floppy
mkdir -p /mnt/floppy/boot/grub
cp -pa /boot/grub/* /mnt/floppy/boot/grub
umount /mnt/floppy

Create a text file called /home/stuff and add these lines to that file
##
root (fd0)
#the following is all one line
install /boot/grub/stage1 d (fd0) (fd0)/boot/grub/stage2 0x8000 p (fd0)/boot/grub/menu.lst
#
quit

Install grub to the floppy disk with this command:

grep -v ^# /home/stuff | grub --batch


2. Create Grub Boot CD from that floppy

Make a directory and cd into that directory.

Copy the entire boot disk to a file
dd if=/dev/fd0 of=boot.img bs=10k count=144

Make the iso image with boot.img ( and boot.cat if you have one )
mkisofs -r -b boot.img -c boot.cat -o bootcd.iso .

Make the bootable cd
cdrecord -v speed=4 dev=0,0,0 -data bootcd.iso

Here are the official instructions to create a Grub CD:

http://www.gnu.org/software/grub/man...le-CD-ROM.html

I tried following those instructions. There must be a trick to running the script in a particular location. I ran the following:

I got this error:

If you want to make the iso image directly without making a floppy, you could try this...

I eventually succeeded after change the word 'iso' at the end to /mnt/iso I had put the iso directory in the mnt folder.
