Yesterday I decided to get rid of Ubuntu and tried to replace it with AcroLinux. It did not want to "kill" Ubuntu(on Patriot), and finally installed it to another (1TB) drive. Worked. Now, after I installed Microsoft Dotnet by AddRemove Software, I am unable to add or remove anything else, it says system is corrupted.Also can not delete Ubuntu files on bigger hard drive.What can I do about it? I would be really grateful when someone takes the trouble to explain something to me blonde. EDIT: solved
