Copy to a textfile and save the following in between ----- .

------------------------------
unit: sectors

/dev/sdb1 : start= 2048, size= 204800, Id= c
/dev/sdb2 : start= 206848, size= 4096000, Id=83
/dev/sdb3 : start= 4302848, size= 4096, Id=a2
/dev/sdb4 : start= 0, size= 0, Id= 0
------------------------------

To create the partition table run:
   sudo umount /dev/sdX*     (umounts=unmount  *=all partitions)
   sudo sfdisk /dev/sdX < PathToTextFile

(To read the partition table from a storage device - sudo sfdisk -d /dev/sdX > PathToTextFile)
