Windows 10: Windows 7 Shrink Partition without Diskpart, Disk Management Utilities

Hello everybody,I'm running Windows 7 and have a C:\ and D:\ volume on my drive. I'm writing a script to partition either of these and shrink them. The problem is, I neither have Diskpart or Disk Management Utilities installed on my system. I have tried installing diskpart.exe to the system, but it needs Disk Management Utilities in order to function.I have created a C++ application to shrink the partition, but FSCTL_SHRINK_VOLUME from winioctl.h is not available on my system.I have tried using certain PowerShell disk management commands, but only PowerShell v1 is available on my system.Third

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

 

Disk management console view is not up-to-date

i dont know how to fix your disk management, but i can fix your partition problems...




open up Command Prompt with admin rights. (Right click, run as admin)


enter in
DISKPART
list disk

then find the Disk number for your Raid array... lets call it number 7 ( you can tell what disk is what by the total size)
type in

Select Disk 7
List Partition (will give you a list of all the partitions..)
Select Partition 1 (im assuming you only have 1 partition on Disk 7) repeat this step if you have more partitions.
ASSIGN


that should get the array up and running ready to use.


EDITED.

any problems, post back ^^


Still EDITING *Stick Out Tongue

side question, have you tried restarting the PC?

 

Hard disk partition

You can use diskpart or Disk Management to shrink your Windows partition to make space for other partitions.

If your computer can switch to UEFI BIOS mode, you may want to do that. There is a new utility called MBR2GPT.EXE designed for this, but you have to enable UEFI to be able to boot from a GPT-initialized disk.

You might try running diskpart to check if your disk truly only has one partition or if you are only seeing one and others are hidden. In diskpart, use
list volume to display volumes, or select disk 0 and then
list partition to list partitions.
