    Understanding partitions


    The following image is from Macrium Reflect showing my boot drive. This is a 237 GB SSD. I don't quite follow how (or why) there's 4 partitions, one of which is grayed out showing as 455 MB and another 521MB showing as red, suggesting it's near full. Thanks for any advice. Win 10 Version 21H1 (08 Build 19043.1052)

    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

  3. hard partition

    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.
