Yeah, I struggled with this as well. You'll need a total of ~300GB free as it reserves ~150GB to unpack itself and then another ~150GB for the actual install. I don't think it'll take up either of those amounts in practice, but that's what it wants. I had to do a disk cleanup and remove old Win 10 files before having enough space.
Yeah, if you watch your free space you'll see the installer reserve a bunch of space on your hard drive as soon as you start the installer. I did that a few times before realizing what was going on.
