<div style="color:black;font:10pt arial;">I re-tried the process and captured screenshots this time. Images with yesterday's date are using the updated installer. Images with today's date are using the non-updated installer. All images are in date order. For yesterday, the first shows the initial condition, the second with just 2 EFI partitions, the third with unmounted ext4 partitions intended for the root partition, note none of them allow creating a RAID. The fourth image is after a reset, the fifth is with just one bootable EFI partition, the sixth is after another Reset trying to create a RAID, the seventh is with both disks selected and the eighth is with the warning message.</div>
<div style="color:black;font:10pt arial;"><br clear="none">
</div>
<div style="color:black;font:10pt arial;">Today's images start with a Reset condition. The second image shows one disk with an EFI partition an unmounted partition for root with the second disk formatted with a 1M partition and the other partition for root so that both disks would have identical sized partitions. The final image shows two boot partitions and remaining space partitioned for the root file system. Again, none have the option for creating a RAID.</div>

<div style="color:black;font:10pt arial;">I have searched the web and what I have found (including the Ubuntu RAID guide) is either outdated or wrong. In the installer (either the default or updated one):
<div><br clear="none">
</div>
<div>If I select "Use as Boot Device" for a device then the device is not shown as a device for "Create Software RAID"</div>
<div>If I select "Use as Boot Device" for a device and "Add GPT Partition" (to create an unmounted partition for root) then I can't select a specific partition in "Create Software RAID"<br clear="none"></div>
</div>
</blockquote>
<div><br clear="none"></div>
<div>If you create an unformatted partition, it should show up in the "create RAID" dialog. The defaults are to format and mount the partition and then it won't show up. Perhaps we should also show free space on drives in this dialog and create the partition automatically if they are selected...</div>

<div>Hope the above helps. I've wanted for a while to add a guided option to be shown if there are multiple disks of around the same size but I've never gotten around to it...</div>
