    Allocate more disk space to system drive


    Hi, I need to Allocate more disk space to system drive, there are two partitions, C:50 GB, D:70GB, I don't have any other partitions, there's 10 gb free space on D drive, which I need to allocate/merge for C drive, so that OS drive has more free disk space, without Formatting Anything, data loss. How can I do this?

    :)

  2. Reclaim Un-allocated Space (Formally System Reserved)

    Hello,

    I previously had run low on disk space on my Operating System Drive (SSD 250GB), my operating system (Windows 7) created a system reserved space (100MB) and placed the boot files there, this creates a warning on log in that a temporary paging file has been
    created.

    I have now cloned this drive to a new 1TB Corsair SSD (Including the system reserved partition) with Active Boot Disk software. I have reclaimed un-allocated space on the new drive which was not identified during the cloning process. As the boot files were
    being stored on the system reserved partition, I conducted a "boot fix" on my Windows 7 Disc. This placed my boot files into the main partition and then I proceeded to make the main partition active and deleted the system reserved partition (now un-allocated).

    Windows now boots from the main partition as intended,

    However in Disk Manager, an un-allocated space created by the system reserved function exists and the Temporary Paging File Warning still appears on start-up, even though the new SSD has 800+GB of free space and the main partition is the
    boot partition. Also, the left most partition is the 100MB un-allocated space that I wish to reclaim but the option to extend the main partition is greyed out in and not available in active boot disk software and disk manager. I have tried to make the disk
    "dynamic" but it warns me there is not enough "space" on either partition to do so, which is simply not true.

    TLAllocate more disk space to system drive :DR

    I want to:

    1. Merge the left most 100MB un-allocated partition (previously system reserved) with the main 800+GB partition
    2. Remove the temp paging file alert on start up
    Thank you in advance for any advice.

    Wade.

    Windows 10 Disk Management - cannot extend C: drive to allocated space

    Hello, I followed all of the steps listed and it is still not working. The issue may be that the unallocated space is located on Disk 1 when my C: drive is on Disk 0 and I cannot seem to get them both on the same disk. Do you know if there is a solution
    for this?
