As a rule of thumb the floor boards you install should cross perpendicular to the joists under the sub floor.
How to lay solid wood flooring on floorboards.
Remove any base or shoe molding around the perimeter of the room.
Align the edge of the board with the chalk line and drill pilot holes down through the hardwood plank and into the sub floor and joist.
The nails or screws should be approximately 300mm apart to offer optimum stability.
Check your sub floor condition.
Next lay the first row.
Starting in one corner of the room spread in excess of 2 board widths of adhesive along the starting wall sub floor using a 3mm toothed trowel.
Use wood or drywall screws to attach the substrate to the floor joists.
Begin by selecting a long board to start the first row.

Glue will typically set in about 60 minutes hold your trowel at a 45 degree angle spread the glue in small sections.
Pick one that is straight.
Installing solid wood flooring onto concrete use a flexible wood to concrete adhesives such as laybond or soudal polymer.
Using solid wood flooring when installing a solid wood floor each plank should be fixed down directly onto the existing wooden floor boards by either secret nailing or secret screwing.

If the sub floor above is more than 1 inch thick this rule can be bent in many.
At this stage you want to eliminate any squeaks in the floor.
