windows - Shrink C: with GParted

I tried to shrink the C: partition on my PC to make space for a GNU/Linux System. My Drive is GPT formatted and has these partition on it:

DISKPART> lis par

Partition ###  Type              Size     Offset
-------------  ----------------  -------  -------
Partition 1    Restore            450 MB  1024 KB
Partition 2    System              99 MB   451 MB
Partition 3    Reserved            16 MB   550 MB
Partition 4    Primary            464 GB   566 MB
Partition 5    Restore            505 MB   465 GB

When I try to shrink the Primary Partition, Windows tells me that I cannot shrink C, because there is no free space left.

Is it save to shrink C: with GParted from a Live GNU/Linux System or will I break something?

Edit: Can I also move the last Restore partition or is it required at that place?
