1. Yes, used root

2. 0 bad blocks

3. ./support_files/installFM.sh: ./support_files/installFM.sh: Input/Output error

1. use your root account or account with sudo permissions. Since you had installed, I think it won't be the reason.

2. check disk 
$ sudo badblocks -v /dev/sda10 > badsectors.txt

3. check if there is any error in /opt/UMM/install.log.
