Windows – Shrinking a partition in windows 7

hard driventfspartitioningwindowswindows 7

I am trying to shrink my C: drive to make another partition where I am planning to install Debian.

When I try to shrink the partition, it says:

Size of available shrink space in MB = 0

Is there anyway to go around this?

I am using a laptop with 64 bit Windows 7.

The hardrive has 673ish GB of space and has got 361 GB of free space on C:.

Well i wanted to upload a picture but i need at least 10 reputation… the disk manager on win7 showed
spaces on disk0, 2 without name and C:, the first one 25 GBs Healthy Primary partition, the second one
shows system reserved 100 MB NTFS Healthy (System, Active, Primary Partition) and the last one C: 673.54 GBs NTFS Healthy(Boot, Page File, Crash Dump, Primary Partition)

When I install Ubuntu and other similar linux distros, it allows me to shrink the Windows partition during the install.

The Debian resources show a similar functionality as well.

To losslessly resize an existing FAT or NTFS partition from within debian-installer, go to the partitioning step, select the option for manual partitioning, select the partition to resize, and simply specify its new size.

It's a good idea to back up your data first, if you can.
