Re: [ros-dev] 1st stage gui installer partition manipulation

[Andrew Green]

I do remember looking at IOCTLs. Someone on irc seemed to think it was
a bad idea. I can't remember why.
It seems to be the only way. Apart from manually doing it.

I suppose I can just use IOCTL_DISK_SET_DRIVE_LAYOUT_EX to set the
partitions and then it's done.

I still think you need to format using the other method after this.

The resize functionality isn't in that article. Though I'm sure it
exists, just that article is out of date.
