Hi,

I am trying to install kali 64 bit version on a fully formatted version. It shows the below error while loading the from bootable dvd but continues.
mount: mounting /dev/sda on /media failed: Invalid argument
unmount: can't unmount /media: invalid argument
mount: mounting /dev/sda on /media failed: Invalid argument
mount: mounting /dev/sda1 on /media failed: Invalid argument
unmount: can't unmount /media: invalid argument
mount: mounting /dev/sda1 on /media failed: Invalid argument
mount: mounting /dev/sda2 on /media failed: Invalid argument

But in the further steps of graphical installation it trows a error in the system installation phase saying. "Could not load the base system.system could not figure out how resolve and network mirror is not configured properly" (message may not be the exact one but similar to this). after this i could not go further. I did a lot of searching to resolve this and found that we need to mount the dvd-rom manually, so i tried "mount /dev/sr0 /media/cdrom". But it threw an error saying "not able to mount Input/output error". Now i am out of options and not able to figure out how solve this. Could anyone be able to help me in this.
DVD drive is MATSHITA DVD-RAM.

Regards,
shank
