Hi Farhan,
You may wish to consider using the 'Raspberry Pi '
SD card copier' next time to duplicate the image to a smaller SD Card see:
.
The SBITX card image can then written to any size SD Card - provided the contents fit.
When reinserted into the Pi in the SBITX, the partitions can then be resized to the full size of the card easily using the 'raspi-config' program
- sudo raspi-config from a terminal
- Choose Advanced Options (option 6)
- Expand File System (option A1).
Paul.
