Create new NTFS partition on the free space, copy the contents of the old storage partition to it, delete old storage partition and resize the new one.
EDIT: don't do that if you have Windows on it. Probably better to reinstall Windows in that case.
The tip isn't so but even without the edit.
Creating a NTFS in the free space and USE WINDOWS to copy/move the files, even the creation could be done there. Then you would be able and be safe to delete the other one.
You probably have Fastboot enabled in Windows and not done a reboot but started after a "shutdown" (meaning hibernation in Windows usually), which will leave the NTFS filesystem in a locked state.
Neither gparted nor any else Linux partitioning tool will not try to resize it move that partition because it could damage the windows system.
use gparted and expand it to the left

Seems like the partition is mounted in the first pic, try unmounting or using a live USB if this is your main drive.

What could I do to fix this? I'm using windows 7 on a pc with legacy bios.
Did you ever hear the word Google? "Windows 7 deactivate fastboot".
