Extending allocated primary partition with preceding unallocated volume












1














I tried to make a dual-boot system on my Razer Blade.
When I allocated a seperate partition for my Linux installation,
I suddenly got a new unallocated partition in front of my Windows partition.
Now I can't merge the C partition with the unallocated space in front of it,
nor can I extend the partition to have enough space to be usable with my desired Linux installation.
(TLDR) How do I make the unallocated space usable again?

          The unallocated space is in the wrong place. You may only extend a partition
          downwards, so this space must follow the partition of C.



          You need to boot a partition editor, since you cannot move C while also booting
          from it. Then you will need to move C up to overwrite the unallocated space.
          This will make this space contiguous to C.



          You should then boot into Windows and resize C. It is best to resize Windows
          using Windows. The bootable partition editor might possibly make a mistake
          when handling sensitive Windows files.



          This operation is dangerous, in the sense that a mistake can make the disk
          unbootable. It is best to take a backup image of the disk and have a bootable
          media of the backup program that can restore it in case of a severe problem
          (and to test it before starting).
