  1. I cannot extend my primary partition on my C drive because of an EFI System partition being...


    Good afternoonat the time of typing this!So basically what is happening is that I'm trying to extend my primary partition on my C drive to claim back 62gb of unused/unallocated storage. But there is a problem. There's an EFI System partition in the way that I can do absolutely nothing to in order to be able to extend the primary partition. Here's what it looks like:And when I right-click on the EFI partition:I have no idea what to do and have spent a long time trying to look for a solution. The reason why I have 62gb of unallocated space was because a few months ago I was trying to install/d

    :)

  2. Efi partition between two partitions

    Hi,

    I have an asus tuf fx55dt laptop with a 256gb ssd that has windows installed on it and a 1 tb hard drive as well.

    I am going to list the series of events that took place :

    1) I installed ubuntu by creating a 300gb partition on my hdd.

    2) ubuntu was not booting up without my charger connected so i decided to remove it.

    3)ubuntu was installed in a 292gb parttion and a 500 mb efi partiton was also made on my hdd.

    4) i deleted the ubuntu partition and an unallocated space of 292gb was made.

    Then i tried to extend my 640gb partition in order to have my full hdd space back. But my 640gb partition did not extend to take up the 292gb unallocated space because the 500 mb efi partition is in between the two major partitions. Also my 640 gb partition
    turned into a simple volume from a primary one.

    So now i have a c drive(ssd) with my windows installed and having a seperate efi partition of its own and a d drive(hdd) that has no os on it but has a 500 mb efi partition in between my major partitions.

    Also i think my booting still takes place through the d drive efi partiton becuase whenever i boot into my pc first grub shows up followed by the windows bootloader.

    I need to get my hdd space back. Please help.

    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
