I looked for a Thread that I was suggesting this tactic when I was having issues installing Mint on my old Acer Aspire, but could not find it so posting it here. Thanks to cat1092 and others for this site, it is quite a good read. This one talks about how OEM's use partitioning schemes to block you out from installing Linux, and quite effectively I might add. Perhaps a bit of a Conspiracy I don't know, but it sure makes it harder to install Linux and could cause damage to your system. Even a simple Partition Block can make it hard for a noob to install a linux system as in the one that I did with my Acer. With mine, it was mostly a lack of Drive space that they might have done it this way, but, they could have made it easier still.
What they do...is put a small Partition at the End of the Drive Space so that one has to re-size a partition in the middle of the drive to gain space. Then you would have to Move the small partition at the end back to the Beginning of Drive space so that Linux could have some free space at the End to use. Most of you know this but I found it very interesting and learned some stuff.
