eBAY Item Listing. ^So I bought this old laptop on eBAY, for $40's. So far, the only problem the seller has told me about is it loading up, and a screen with a ? mark appearing, and saying "NO OS". I wanted to know if it's possible to fix it. I'll get it in a couple day, and wanted to know what to do. Before, I bought it, I went to Unbuntu, or something like that, and requested a installation disc. Does Unbuntu work as a OS? Can I install it on the iBook? If not what should I do?
