If you are running Linux system and you have an additional disk in your computer, you can see that the partion name will change after you reboot your operating system.

That's issue is not good for users who want to have a static link of those partitions.

Here is the solution to resolve your problem.

Use this command to determine the UUID of your C: drive:

sudo blkid

Example output:

/dev/sda1: UUID="f1b3915e-3c86-a3ec-3273-43967f134ce5" UUID_SUB="f48bf957-6f67-171f-ea75-29ddbd401637" LABEL="ubuntu:0" TYPE="linux_raid_member" 
/dev/sda2: LABEL="Win" UUID="28A139962EFFC093" TYPE="ntfs" 
/dev/sda3: UUID="571a61fe-6e6f-45d0-9fe1-832f28519f96" TYPE="reiserfs" 
/dev/sdb1: UUID="f1b3915e-3c86-a3ec-3273-43967f134ce5" UUID_SUB="d0318ec5-9e4c-a864-7906-2d43bcbd0374" LABEL="ubuntu:0" TYPE="linux_raid_member" 
/dev/md0p1: UUID="88dc483f-aef9-454b-b744-2c3e3202a198" TYPE="swap" 
/dev/md0p5: LABEL="Home" UUID="b632fe56-564e-4d3f-833a-fde68fd1dd32" TYPE="ext4" 
/dev/md0p6: LABEL="Ubuntu" UUID="da84c996-f7d0-4fe8-8822-407e4f6c5c22" TYPE="ext4"

Find the device corresponding to your C: drive (use label if it's difficult) and add such line into your /etc/fstab:

 UUID=AC7A30A47A306D68 /windows        ntfs    defaults,umask=007,gid=46 0       0

Reboot (or do sudo mount -a) and see your drive mounted in /windows.
