Can I use DVD disk for installing boot camp?

You mean, Can I use DVD disk for installing Windows.

And yes, you can.

One solution was I have seen before is unmounting the iso file:

1)open disk utility

2select and unmount the dmg file

3) try again

Although this did not work for me. I actually did a software update that restarted that also restarted the computer. Try also restarting the computer and try bootcamp again.
