:( The OS is no competition to Win7 but if you are stuck in Windows 8 that really sucks man. I suggest deleting the $Windows-BT folder and starting again. Check out reddits /r/windows10 they have a few guides.

Installed Windows 10 on my Mac using Boot Camp. It's a huge mess. Microsoft never cleans up their code. 24 GB after a clean install isn't something you can brag about. If they started clean with Universal apps and an UNIX kernel, then I would have run it on my Mac from day one. At this point Ubuntu is the better option.

That's too much. My Linux install is just under 10GB with all of the software that I use (Matlab, LibreOffice, TeXworks + a lot of packages, various compilers and browsers, some graphics software like Inkscape and QtiPlot), and even that's a lot. In contrast, my first PC was a Pentium III Dell machine which had a 10GB hard drive, and I had lots of programs and games installed with plenty of free space on the disk.
