Looks like it might be a bad hard drive. Switched to Multiple Partitions - Single Disk and it definitely got farther, but once it got to /dev/sda20 it told me there was a filesystem error.
Calling this a bad hard drive. I’ll retest after I reinstall.
Doing some testing uploading ChromeOS to fog with a Dell GX620 and Neverware CloudReady ChomeOS.
I did a fresh install of ChromeOS, did a full host registration and inverntory, then tried to upload it.
Got the following error:
e2fsck failed to check /dev/sda20 (shrinkPartition)
Args Passed: /dev/sda20 /images/0013720ddef0/d1.original.fstypes :1:2:3:4:5:6:7:8:9:10:11:12:13:14:15:17:19:21:22:24:25:26:27:1
I am uploading Single Image Resizable with a compression of 5.
Thank you
@Tom-Elliott Great, thanks Tom. Good to hear. I signed up for a few bugs with a beta anyway. 
Same. Hoping to get this resolved soon because we’re about to do a huge FOG reinventory after moving from .32 to 1.3.0 RC-9.
