To make a long story short: I got tired of my netbook being so slow with Windows 7… in the meantime I have tried some Linux distros which did not treat my GMA500 really well or were not as responsive as I would like. On the other hand, Windows 8 were also malfunctioning in my netbook (GMA500 also being the cause of the Blue Screens of Death that I kept seeing every once in a while.
In the end, I decided to give Zorin OS another try. I created a live USB of Zorin OS 7 Lite using Unebootin and installed it on the second partition of my netbook’s HD (the one acting as storage and back up space for the machine – I didn’t realize that until I booted into Zorin) and I liked it quite a lot – it also identified and set up my GMA500 correctly. Since I was so pleased with the new OS, I decided to uninstall it and use the primary partition, so that it would boot along my Windows 7 Home Premium installation. Alas, something went wrong in the process (despite the fact that I have installed quite a few Linux distros, I was never fond of the partitioning options and never got to understand them) so I ended up not only with a non-bootable C: drive, but also all the entire contents of the second partition were also gone! There was a lot of non-backed up stuff there, ranging from movies and music to documents and other personal files (e.g. images) which is rather impossible to retrieve from other sources.
After realizing what was happened and that there was no way of recovering, I decided to enjoy a fully formatted disk after a long time and take the time to install a fresh copy of Zorin OS 7 Lite. Everything was set up in a few minutes (I became familiar with the process) and I started installing my favorite apps, including MS Office and Sugarsync using Wine, and Dropbox and Skype using the Software Center and setup package respectively.
So far I am pretty pleased with the behavior of my netbook; in fact I think that it has been transformed into a useful machine after a long time (during my last business trip, I decided to travel with my 17-inch/almost 3 Kg Toshiba laptop instead of carrying my lightweight but sluggish netbook with me). Operation is smooth, YouTube videos also play smoothly. I am still trying to figure out which app I will need to install in order to set up my netbook according to my needs so I guess that I will have to update this post after a while.
