![]() ![]() Unfortunately replies get tied to other responses and are lost in the shuffle and you might not have seen my earlier reply. I'll update if/when I find anything useful -) I used to create bootable ISOs quite often because I was in the same boat as you (had to use an ILOM/DRAC to build systems with no PXE access). ![]() 1 root root 20 May 17 11:26 /etc/alternatives/mkisofs -> /usr/bin/genisoimage 1 root root 25 May 17 11:26 /usr/bin/mkisofs -> RHEL-7.1 Server.x86_64]$ ls -l /etc/alternatives/mkisofs Genisoimage-1.1.86_64 : Creates an image of an ISO9660 file-systemįilename : RHEL-7.1 Server.x86_64]$ sudo yum whatprovides */mkisofsįilename : RHEL-7.1 Server.x86_64]$ which RHEL-7.1 Server.x86_64]$ ls -l /usr/bin/mkisofs Loaded plugins: langpacks, product-id, subscription-manager RHEL-7.1 Server.x86_64]$ sudo yum whatprovides */genisoimage Hey Tom, I am going to attempt this on my RHEL 7.1 workstaiton, bu tin the interim. Some specific help on how this is done with RHEL 7.1 would be appreciated. I have also tried mkhybrid without success.Įvery attempt so far results in a non-bootable image. ![]() new.iso -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -J -r /storage/temp/RWISO/ rhel-server-7.1-x86_64-dvd.iso /storage/temp/ISO/Ĭopy the entire mounted ISO to another folder /bin/cp -pRf /storage/temp/ISO/ /storage/temp/RWISO/įrom the /storage/temp/RWISO/ directory mkisofs -o. Using original ISO rhel-server-7.1-x86_64-dvd.iso There is tons of examples on how to extract, modify, and recreate bootable ISO files but nonthing has worked so far. Because the servers are headless, and because the servers do not have built-in DVD/CD drives I need to create a bootable ISO file that is mounted using a virtual CDROM feature. I have a rack full of headless servers I need to install RHEL on. ![]()
