Windows 10: CANNOT CREATE NEW PARTITION FROM C DRIVE

I've created partitions on other computers for years and never had this message come up. I don't want to click on yes unless I know what it's about.

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

 

Unallocated Space to C Drive

Thanks

Hi Prasad,

Thank you for posting in Microsoft Community.

I understand that you are trying to extend the Volume of Drives and create partitions from C: drive.

I would suggest you to follow the steps and check if it helps you.

• Press Windows + R keys, type diskmgmt.msc hit
  enter.
• Disk management will open. Right click on the C: drive
  below in the segments of the partitions.
• Select Shrink Volume. Select the Amount of space
  you want to extend in MBs (1GB = 1024MB).
• Follow the instruction and check if it creates a Unallocated Drive.

Later after the Unallocated drive is created follow the below steps to crate a partition.

• Right click on the Unallocated drive and select
  New Simple Volume.
• Select the Drive letter and follow the instructions and check if it
  creates a partition.
• Follow the same to Create partition.

Note: C: drive must be not less than 100GB if you are using a 1TB hard drive. partitions must not be more than 3 drives to have a better functioning of the system.

Keep us posted to help you better.
