I use a Toshiba Satellite L305 laptop that is several years old. It still has the original Windows Vista OS that came loaded on it. I disliked Vista intensely from the start. I intended to upgrade the OS to Windows 7, but my opinion of Windows 7 is only slightly higher than of Vista. Now comes Windows 8, and even if this laptop were compatible with Windows 8, I don't even want to think about messing with it on this laptop. So I started thinking about Linux. I did a web search for Linux on Toshiba laptops, and I found a page with a long list of Toshiba laptop models including mine, and notes from 2009 from a user about his installation of Ubuntu 8.10, which seemed to go well. Considering that that version of Ubuntu has long since been superseded, and that I have otherwise no experience with any version of Linux, I am asking the community in general for advice about what to do at this point. The question of setting up a dual-boot also arises, but my question regarding that is how much more disk space does that require? As this unit has only a 250-Gb hard disk and I don't know if buying a larger disk is worth it at this point.
