CentOS custom ISO installation - /dev/root does not exist

I am building a custom ISO for CentOS 7 and for now I am just intending for this to be an absolute minimal install (a proof of concept basically). I am re-creating the ISO via using mkisofs. The command I entered is: Mkisofs –o custom.iso –b isolinux.bin –c boot.cat –no-emul-boot –V ‘CentOS’ –boot-load-size 4 –boot-info-table –R –J –v –T isolinux/ This successfully created the iso and allowed me to mount it in the optical drive of VirtualBox. Upon installation I am receiving an error within the rdsosreport.txt that says: > localhost dracut-initqueue: Warning: Could not boot. > > localhost dracut-initqueue: Warning: /dev/root does not exist So far I have: copied .treeinfo, .discinfo into the root directory of where I am making the iso. Created subdirectory /isolinux with all the /isolinux data from the latest CentOS-7-x86_64-Minimal-1503-01 as well as the /images and /LiveOS directories. I have also copied over the repo .xml file into the root directory. I have tried a multitude of kickstart files, but the current version I am using is ultra-minimalistic just to get this to work at some point. install cdrom text keyboard us lang en_US.UTF-8 rootpw --iscrypted $6$XRIetvtFyLXRFVzZ$jX7xRxsN6M.DIqwJ9DQui9ytaqK3IAzauSqB4zeRNvMKJo6xCJQAk90XIaxh.SBn0IBtyZM7ZlHK8eSk55VnG0 timezone America/New_York --isUtc clearpart --none --initlabel %packages @core %end My ks.cfg is located in isolinux/ks/ks.cfg and when I boot into the system I am running is linux inst.ks=cdrom:/dev/cdrom:/ks/ks.cfg I'm a little lost on where to investigate further as all I am trying to do is load a very simple kickstart file to get Linux to do a one-button install. I don't necessarily need to be told, just to be pointed in the right direction as I've tried quite a few different kickstart configurations and have come up with the same error. edit: I have gotten this working by editing the isolinux.cfg file and changing the volume ID to my -V volume ID set in my mkisofs and then selecting this menu option when doing my installation. append initrd=initrd.img inst.stage2=hd:LABEL=CentOS quiet inst.ks=cdrom:/dev/cdrom:/ks/ks.cfg I have other errors within the iso that I'm investigating now due to the fact my kickstart file is so barren.
