 On a blank example disk `/dev/sda` you can fulfill the requirements (One `EF00` partition with a file system plus one `BF00` partition) for example like so:
 ```
-sgdisk --new '1::+100M' --new '2' --typecode '1:EF00' --typecode '2:BF00' /dev/sda
+sgdisk --new '1::+512M' --new '2' --typecode '1:EF00' --typecode '2:BF00' /dev/sda
 mkfs.vfat /dev/sda1
 ```
-> `--new '1::+100M'`: Create partition number `1`. The field separator `:` separates the partition number from start sector. In this case start sector is unspecified so start sector sits at whatever the system's default is for this operation. On a blank disk on an Arch Linux live CD ISO image this will default to sector `2048`. Partition ends at whatever the beginning is `+100M` meaning plus 100 Mebibytes.

 > `--new '2'`: Create partition number `2`. Both field number 2, the start sector, and field number 3, the end sector, are unspecified, there's no field separator `:`. Field number 2 will be the first free sector - in this case right after partition 1 - and field number 3 will be end of disk. Thus partition `2` will fill the remaining free disk space.
