Hello, Thanks for the information but the problem isn't booting. I've updated syslinux to the required version to support booting isos from usb.
The process is somewhat like: mkisofs creates install disk (.ISO file) isohybrid transforms the iso file so that it can be DD'ed to an usb disk dd if=ISOFILE of=/dev/usbdevice boot machine with usb device. Boot occurs normaly as i'm presented with splashimage. Select install option (subset from isolinux.cfg): ... label etva-smb-kvm-usb menu label ^Install ETVA-SMB-KVM from USBSTICK (This will erase all disks) kernel vmlinuz MENU HIDE append initrd=initrd.img ks=hd:sdc1:/ks.smb.kvm.usb.cfg ... Instalation starts... because the KS file has "askmethod" directive anaconda askes for media where it can find the iso files. I select /dev/sdc1 (usb drive). In this point it fails because anaconda finds the exploded tree of install in /dev/sdc1 and not the iso files. Booting the ISO file from CDROM and using a kickstart with "cdrom" method it works fine.
