I have installed centos on my /dev/sda9.
There is windows 7 on my first partition.
Now I try to install ubuntu on /dev/sda11
While installing,it shows the following error.
migration-assistant needs to mount a partition,but cannot do so because the following mount point could not be mounted:
please close any application using this mount points.
would you like migration-assistant to try to unmount these partition again?
How do I address this error?
