post-partition-magic, the partition table was "funky" - when I got to the partition editing part and selected disk druid, it popped up a warning about a recursive partition table being defined (the resulting screen made it look indeed like that) and I hit "Ignore" (*not* "Cancel") initially and 1 other time. Eventually I got the popup again while trying to create another partition, but this time (3rd time overall for this warning dialog) I hit cancel instead and generated a traceback (soon to be attached to this bug report) Important to note that on the next boot I hit cancel the first time the "recursive partition table warning" dialog popped up and got a notice that it'd need to initialize the device, which I agreed to and it did fine, leaving an empty partition table, and after that point everything worked fine.
Created attachment 47800 [details] anaconda dump of the traceback
Are you seeing the same issues with Beta 2?
there's no way to tell - the partition table got cleared/initialized (second paragraph of original bug report) so I no longer have the setup needed to test.
If you can recreate the original state of the machine and see this error again please reopen this report.
