Typically, when the create partition command is invoked, there's a default alignment of 1024, at least for the Windows 7 version. Say these commands were issued.

select disk 0
convert gpt
create partition efi size=40 offset=1024
format quick fs=fat32 label="System"
create partition primary
format quick fs=ntfs label="Windows"

When I checked for the alignment of the "Windows" partition, it said the offset was 41984kb. However, is it possible to have an align of zero like so?

create partition primary align=0

Then, I'd save an extra megabyte of space and have an offset of 40960, which is still divisible by 1024, making it still optimal for Windows 7?

If you would be able to change the offset to 0 and therefore let the first partition start at sector 0 where do you want to write the partition table?

hence: No, you can't use offset 0.
