Not so. >From "info grub" I got this info and used it and would still like to use it, rather than floppys or pendrives. I keep my windows MBR clean by using 'diskprobe' and 'disksave' after a linux install - reinstalling a clean MBR. To boot linux I then used 'mkisofs' from the "info grub" to make a bootable grub CD: <quote>3.4 Making a GRUB bootable CD-ROM ================================= <snip> Here is an example of procedures to make a bootable CD-ROM image. First, make a top directory for the bootable image, say, `iso': $ mkdir iso Make a directory for GRUB: $ mkdir -p iso/boot/grub Copy the file `stage2_eltorito': $ cp /usr/lib/grub/i386-pc/stage2_eltorito iso/boot/grub If desired, make the config file `menu.lst' under `iso/boot/grub' (*note Configuration::), and copy any files and directories for the disc to the directory `iso/'. Finally, make a ISO9660 image file like this: $ mkisofs -R -b boot/grub/stage2_eltorito -no-emul-boot \ -boot-load-size 4 -boot-info-table -o grub.iso iso <snip> </quote> Genisoimage doesn't make a bootable CD, at least not with these parameter - and nothing I've tried so far works. Can someone can tell me the correct options? Or even if genisoimage is capable of doing what 'mkisofs' did? I know I can boot from floppy (but floppys are disappearing), or pendrive (if I wan't a pendrive to shrink to 1.44MB). I really don't like losing the bootable grub CD option. Thanks for any clarification. lynnevan </BODY> </HTML>
