I have downloaded bt4.iso to a DVD+R and used md5sum to confirm it was not corrupt. My goal is to keep Ubuntu 10.04 as my main OS and use bt4 to assist me on some projects. I have read the tutorials and how to's on this site and others but two things concern me that I hope someone will take a few minutes to help me with. My concern is two fold:
1) the only dual-boot scenario I have found is with Windows OS not Linux( I'm missing it somewhere certainly) and if the install procedure is the same for both OS's I will go ahead with it.
2) I would like bt4 to work in concert with Ubuntu and not overwrite or partition HD space so I lose or crash Ubuntu.
I guess there are no guarantees but if you could nudge me in the right direction I'd be grateful.
Backed up data and installed bt4 successfully-Thanks Archangel
