    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

    Lost Logical Partition after Windows 1909 Update

    Windows 10 update 1909

    Hi Sarthak

    No you do not need to update to 1809 - 1903 if you are currently on version 1803, then version 1909 will appear in the list of updates and will automatically be installed on your PC since 1803 has run out of support

    You do not need to do anything, 1909 is currently spreading around the world, just give it time to appear in the list of pending updates . . .
