Suppose I have Debian running in my system, and have a knoppix iso at the root of a partition.

Now, say I mount the Knoppix iso via loopback.

Then is it possible for me to switch over to knoppix from that Debian system by chroot and run knoppix normally, from runlevel1 to entering Runlevel5 and GDE or KDE?

I know it is possible, because that's what Knoppix does when the BIOS hands over the controls to the Bootloader, but I can't find posts specifically on the issue. There may be - and I believe there are - but my search using the key words like "switch loopback iso chroot boot knoppix" does not yield encouraging results.

Could any of you, who is aware of such a post, direct me to that link please?
