Yes it is possible with GNU Linux fdisk in expert mode.

Boot systemrescuecd (CD/USB) or GNU/Linux LiveCD
that has a recent version of GNU linux fdisk binary available.
run fdisk -l from root term or console

Then run for instance, if the drive shows to be
/dev/sda as determined via the output of fdisk -l.
Run fdisk as below:
fdisk /dev/sda
Then at the fdisk prompt type:
now you should be in expert mode and at the expert mode prompt.
