I decided to install Windows 7 next to my Ubuntu setup and started to follow this instructions. Currently i'm on the third step. But when i try to mount the file system that i noted down, it says "mount: special device /dev/sda6/ does not exist". Here is a picture of the current partitions. Since the instructions says that i need to note down the partition name, can i assume that i can still get back what was on my Ubuntu file system?
Is it possible to make unallocated partition in the image, functional again? Did my whole Ubuntu installation got wiped out? Should i try using testdisk to get back the unallocated partition?
