I have used SystemRescueCD in similar cases. It has an NT Password retrieval tool on the disc that comes in handy, and it can also just blank the password and let you back into your system. Otherwise, Ubuntu will resize your windows partition(s) and make space for itself during the install procedure. You will still be able to access your windows system (after you sort out the password problem).
I wish you luck. I use Macintosh, Linux, and Windows (BSD and Minix as well but mostly as toys), when each is needed. Windows and Linux are perhaps as different as operating systems can get, and I know that the transition can be insanely difficult. There are several different blogs that have posted migration tips that you may find handy. A quick google search would be useful.
thanks guys, I used the NT password retrieval earlier and problem is, under user account and password, it showed no accounts which i guess means my account was actually deleted and it was the only account on the pc as i was the only user.
i installed ubunto 9.04 after a few installs and reinstalls to change preference, i have it working to my liking. love it. i hate myself for not doing it earlier. now i'm even happier i chose ubuntu 8.04 rather than windows on the netbook i have coming in the mail.
i was in the hunt for a C++ compiler and i could not figure out how to get the file i needed for GCC because all the directories had multiple files and folders with no explanation on what was what.
i got netbeans from sun. i know its an IDE but i dont know if it has a compiler or a way to output the program which i need in a class in school. in windows, all my C++ in windows outputted to a DOS/like environment so i'm wondering if i'll have the same with netbeans or anything else on linux. any ideas?
