I was trying to extroot with this first command (mount /dev/sdaX /mnt) but failed and got this message…
“Mount is denied because the NTFS volume is already exclusively opened. The volume may be already mounted, or another software may use it which could be identified for example by the help of the ‘fuser’ command.”
Then I try to use umount and got “Device or resource busy”
I would appreciate some help please. I have USB stick formatted with ext4.
Thanks a lot.
