Convert GPT to MBR double check please.

So I'm trying to have Windows dual booting but don't currently have the right tables and stuff.

Partition table: GPT
File System: ext4
Running with bios-grub

I'll be using gdisk to do this but just need to make sure that I'm doing it properly. These are the steps gdisk ask and the options I choose:

1. hard drive: /dev/sda
2. option R : recovery and transform
3. option G: convert GPT to MBR then exit.

Now this is where I'm a little unsure, I'm prompted to give an 'mbr command', here are the options:

MBR command (? for help): ?
a       toggle the active/boot flag
c       recompute all CHS values
l       set partition as logical
o       omit partition
p       print the MBR partition table
q       quit without saving changes
r       set partition as primary
s       sort MBR partitions
t       change partition type code
w       write the MBR partition table to disk and exit

Is it safe to just choose 'w' to write and exit?

Thanks for you helps folks
