Hi Toomas,

Format says this What should I change ?

           Total disk size is 58369 cylinders
              Cylinder size is 16065 (512 byte) blocks

Cylinders
       Partition   Status    Type       Start   End       Length %
       =====  ====    ==       ====  ====   ====     ===
           1                         EFI               0  58368 58369    100
