    Installed new SSD, accidentally made main partition too small


    I installed a 1TB SSD and was able to get it Windows 10 working but accidentally made the C drive only 38 GB see pic. What's the best path forward to fix this?

    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. undo partition shrink

    Hi,

    If you accidentally shrink the volume of your SSD partition, there is an option to extend the volume as well. To extend the volume of your SSD partition, follow the steps below:

    • Press Windows key + X on your keyboard and select Disk Management.
    • Right-click the partition that you want to expand and click Extend Volume.
    • Select the amount of space that you want to extend.

    Keep us in the loop with the result.

    Installed new SSD, accidentally made main partition too small

    Partition SSD during windows 10 install

    I'm assembling a new PC and running a fresh windows 10 install. I'd like to know how to partition the ssd into 2 separate partitions during the windows install (I'm using a bootable usb drive to install Windows).

    I want to know if I need to input specific settings for those partitions or if it's all automatic?

    I need one partition for Windows on and another for my documents. The ssd has 960gb size.

    So I'm guessing it has about 60gb over-provisionning. I could leave out a bit more, but it probably doesn't matter that much
