I bought a new laptop, a HP Pavilion 15n-233tu.
It had an Ubuntu 12.04 OS. When I was installing windows 7 it showed 2 partitions. One was labeled hp_tools so I left that one untouched, the other one I formatted and installed Windows 7 on.
But I can't find drivers for it, so I used system restore and installed Ubuntu again.
I also tried installing Windows 8, but that gives an error:
windows cannot be installed because partition is not in NTFS type
So right now I am using Ubuntu and I used a disk utility to change its format, but it gives some mounted error. How can I solve this?
