Is there any chance that my Windows install will fail to boot after resizing its partition?
I remember that I wanted to install Ubuntu as second system on my laptop ~4 years ago, so I used live-USB with GParted to split my hard drive. Unfortunately, after this, Windows 7 failed to load (I do not remember the error text, but it probably went in a boot loop). On the other hand, I did a similar resize several times and I only broke my Windows install once, but I do not know the reason why.
Now I need to install a second OS again but I'm afraid that I might have to reinstall windows after it.
