I really think it would be easier to make a USB key/disk... But, I tried the following yearsss ago... so did not test if it is still working... Copy DVD files to HD (if netinstall, you don't need to copy isos): cp /mnt/cdrom/syslinux/vmlinuz /boot/vmlinuz-c6 cp /mnt/cdrom/syslinux/initrd.img /boot/initrd-c6.img mkdir -p /path/to/c6/images cp /mnt/cdrom/images/install.img /path/to/c6/images/ cp *.iso /path/to/c6/ Add the entry to your grub (change the root to match your setup): title CentOS 6 Install root (hd0,0) kernel vmlinuz-c6 initrd initrd-c6.img You could maybe also directly specify where the images/isos are: repo=hd:sd??:/path/to/c6 And be sure that "/path/to/c6" is not formated as you install... Again, not tested at all... And I guess you will have 1 try only... if it fails somewhere in the middle of the install, you won't have a 2nd chance JD
