hi,
i want to make iso images of red hat 9 disks with mkisofs in the current directory of iso wich is in /home,and contained a file named isolinux.bin,with this command:
mkisofs -o disk2.iso -b isolinux.bin -boot-info-table -R -J -v -T /mnt/windows/disk2
but the process is ending in it's start with this message:
bash:uh ah,I can't find the boot image 'isolinux.bin'
i tried to give the current directory path './isolinsx.bin' and then the full path '/home/iso/isolinux.bin'in the above command but
the output was the same error message,plz help me.

The path to the bootable image is relative to the path you specify. Since you are using /mnt/windows/disk2 as the image directory you should try something like this:
-b ../../../home/iso/isolinux.bin

hi bin/bash,
thanks for reply i copied the ource red hat disk2 to the current iso directory then i tried the "mkisofs -o ./disc2.iso -b isolinuxs.bin .. ./disk2" also i gave the path "./isolinux.bin" but the ouput was same error message:
mkisofs:uh ah,I can't find the boot image 'isolinux.bin"

Lets suppose you have a directory /temp and /temp/boot and you put the file isolinux.bin in /temp/boot, and you put the rest of the files you want on the cd in the /temp directory.

You could make your eltorito bootable cd like this:

cd /temp
mkisofs -b boot/isolinux.bin -c boot/boot.catalog -o disk2.iso .

Everything on the above line is part of the command including the period at the end. The dot represents the current directory (/temp) so the path to isolinux.bin is actually /temp/boot/isolinux.bin. I think the -c is needed and I noticed you dont have that. Maybe you should try using the -c option. This is a catalog of where all the files are located.

hi /bin/bash,
thanks again for your help,i tried exactly what do you said,i made a directory /tmp/boot wich contains the isolinux.bin,the source disk2 is in /tmp/disk2 and the path for distination disc2.iso is also /tmp/disc2.iso the command for mkisofs is what do you write above but the output is this error message:
oh uh,I cant find the boot catalog directory (boot)!
i hope you continue with me for the solution of this problem.

You should just continue trying and adjust your path if it says it can't find a file. Remember the path is relative to the . So if you specify the catalog it should'nt be an absolute path like /tmp/boot/catalog rather it should be like boot/catalog or ../boot/catalog.

Thought I'd post up my own little script and see if it helped you out. I've used this to build a number of isos, and I haven't had a problem with it. If it works for you -- well, then, let me know. Something else for you to try, anyway. :-)

The script, up to and including the final period:
mkisofs -o ./isoname.iso -R -J -V "Distro Name" -hide-rr-moved -v -d -N -no-emul-boot -boot-load-size 32 -boot-info-table -sort isolinux/iso.sort -b isolinux/isolinux.bin -c isolinux/isolinux.boot -A "Install CD" .

I could be entirely misinterpreting what you need, but hey, that's part of the joy of using the Internet and attempting to answer questions while simultaneously looking like you're working, right? Good luck!

$ mkisofs -o my-debian-installer.iso -r -J -no-emul-boot -boot-load-size 4 -boot-info-table -b isolinux/isolinux.bin -c isolinux/boot.cat ./installer-cd

if installer-cd is link you get the problem, for solve the problem use real directory, no links
