Does it say "Login Failed"?

Does it say "Login Failed"?

NO

NO

Did you use the oem install?

Did you use the oem install? (Rather than the text install)

I THINK YES

I don't know what is OEM installation. I boot from CD and then install it.

THAKNX EVERY ONE

OK,Finally I have solved my problem. I saw that I have to type "startx" to boot from Recovery mode (I didn't knew that) So I did that and deleted 3.5GB torrent that I'm downloading After that I able to boot normally. I think I ( though I didn't ) had to mention that my ext3=8.4GB and my swap=1GB Also I had some films inside it. Now I feel that I made stupid decision to install 64bit KUBUNTU 3 times. Should have read those forums. (I'll do this now even I theres no problems.SO much things to learn) Thank you very much "arochester" and every one else. Can some one please tell me how to modify content in NTFS file system And is there any way that I can notice My hard disk doesn't have enough free space
