Me.
I'll post again when my installation finishes.
I at first did go through the setup process under Release Preview. Went all the way to the "install" button. No fuss.
Clean installation done.
<3 SSD.
Activated.
Clean installed from Release Preview (from BIOS boot) using the $40 key. Wiped all partitions by selecting "Custom", the same way it is done in Windows Vista and 7 installs.
You heard it from me.
Hopefully, other people will have the same experience.
