cannot assign write permissions to sda1
 

i want to assign all permissions to my windows partition (titled sda1 in ubuntu) but when i attempt to in the terminal (even as root) it says that it does not exist the command i am using is chmod a=rx sda1 i have also tried several folders and files in the partition, help please!!!

Windows partitions don't support Linux permissions so the chmod command won't work the way you expect it to. You need to mount the partition with the required permissions. Have a look at the man page for the mount command - in it are options such as umask, uid and gid that will allow you to set the access type for the permission.

Please search for mounting fat32 or mounting ntfs partitions - there are quite a few posts here that deal with this.

unmount the windows partition and put this in your /etc/fstab:

/dev/sda1 /home/your username/windows ntfs-3g rw,exec,uid=1000,gid=1000,umask=0000 1 2

Remember to make a windows folder in your home directory first.

Reboot or use mount -a.

You may still find that you aren't getting the expected permissions, if so:
chown -R username:username /home/username/windows
