Can someone explain how I would make a 300mb active partition and another primary of 100% for the remaining space? It looks like the task in 7.5 doesn't like mixing fixed numbers and percentages. If I set a 300mb fixed then use 100% for the next partition it says "The total size of partitions should not exceed 100% of disk 1"
I just need the GDISK equivalent of this Diskpart:
select disk 0
clean
create partition primary size=300
format quick fs=ntfs label="System"
active
create partition primary
format quick fs=ntfs label="Windows"
active
exit
