I have a problem I have not found any solution to, I am not so familiar with ubuntu commands or ubuntu in general. My problem started when I chose in windows 7 settings/ bootloader settings as ubuntu default, and it boots straight into grub, and in grub if I choose windows, it goes to the loader for half a sec, and goes straight back to grub. So I have disabled my windows 7 completely. And I have not found any way to boot back to windows, so I could go to settings and set it to windows... My only option seems to be re-installing the whole Windows 7...thus loosing all my saved games etc... I am fine using ubuntu for basic needs, but I am getting desperate here...
I have no clue how to change Win7 bootloader settings from Ubuntu. A possible workaround could be:
