Windows 10: Can I divide a drive into two partitions after installation?

I have one drive with no partitions. On this drive I have important data.Is it possible to divide the drive into 2 partitions after windows was already installed?My plan was to make two partitions put my important data on one partition and then format the second partition the one that have windows system on it without affecting the data on the second partition. Is this even possible?

W7 Hard drive partition issue

to get rid of that 100 meg windows partition that setup creates for you on a new install on a blank hdd:

- press shift+f10 when on the partition management screen in setup <-- this opens a command prompt
- diskpart <-- start the windows command line partition management tool
- list disk <--- list the installed hdds in this computer for the next step
- select disk 0 <- might have to replace 0 with the number of the correct disk
- clean <-- this will erase all data on the disk you selected one step up- dont use the wrong disk!
- create partition primary <- creates a primary partition taking up all space on the drive, adjust the command if necessary
- exit, exit to exit diskpart and the command prompt
- click refresh in partition manager and select your newly created partition and install to that

 

SSD partitions : divided space on this drive.

i guess thats it for this step. that should be it.

 

Partition or multiple hard drives?

As the title suggests. Is it worth installing say a 36GB drive for the OS soley or partitioning an existing larger drive with either 2 or more partitions? I am currently running Vista 32bit and want to try out 64bit and am sick of reformatting the whole drive. Any suggestions?
