Error convert img to vdi?

Hello! I followed tutorial Why do I have there is an error during conversion?

Converting from raw image file="lede-x86-64-combined-squashfs.img" to file="lede
Creating dynamic image with size 19408202 bytes (19MB)...
VBoxManage.exe: error: VD: The given disk size 19408202 is not aligned on a sect
or boundary (512 bytes)
VBoxManage.exe: error: Error code VERR_VD_INVALID_SIZE at F:\tinderbox\win-5.1\s
rc\VBox\Storage\VD.cpp(6990) in function int __cdecl VDCreateBase(struct VBOXHDD
 *,const char *,const char *,unsigned __int64,unsigned int,const char *,const st
ruct VDGEOMETRY *,const struct VDGEOMETRY *,const union RTUUID *,unsigned int,st
VBoxManage.exe: error: Cannot create the disk image "lede-x86-64-combined-squash

I'm using Windows 8.1. VirtualBox Version 5.1.14 r112924.

I had the same issue. I ended up converting the image using Ubuntu Virtual Machine.
