I have a older macbook, which is a 13 inch laptop. I was running OS X Lion and decided to erase my hard drive and start over with Ubuntu. Now when I try to download Ubuntu or other software, I get an error message that says I do not have enough free disk space to even start the download. How can this be if I just erased my hard drive? In addition to this I am not sure I erased my computer correctly. I am not computer savvy and will appreciate any insight for this problem. Here is the latest error message: Safari could not download the file “regservo_22.214.171.124.exe” because there is not enough free disk space.
