    When 512 appear just modify it to 2048 to 5128 the internal storage will be big. You can go along More like 64GB (1024x64).

    Warning : Never install any os if your disk is dynamic , after 4th partition disk become dynamic , if installed on dynamic disk the whole window will get corrupted
    Tip: change dynamic to basic via any software then go
