Comment 47 for bug 1361951

Being able to reproduce once is unfortunate, but can you reproduce this every time you try to install? If so, have you tried to use the exact same steps on a different machine, or on a different disk, with the same results?

The issue that I have here is that while I appreciate that this issue happens in the wild; I'm completely unable to reproduce it with the various different formatting methods I tried -- I tried full disk, but this rewrites the partition tables so it doesn't matter even if you had data on a partition previously. I tried 'reinstall' (which I understand just formats the pre-existing partitions), and 'something else' (using a manual partitioning, I tried with ext2, ext3 and ext4, etc.).

Given that I'm unable to reproduce this with the various options above, the only thing I can think of by now is that there is some piece of the picture missing. Is the installer booted in EFI? Are you certain that the disks aren't nearly failing and that would explain the issues (especially if it sometimes works, sometimes doesn't, with the exact same process)?

If you can reproduce this *every single try* using a set of precise instructions, please comment here on the bug and set the bug back to New so we can look into these instructions and debug why they cause a failure.
