Bug Description

I realize parted is a few releases behind, maybe upstream has this fixed already? Basically, the disk is shown as empty, running parted manually it complains that it doesn't have a valid fake msdos partition table. Partman log attached.

Looks like I messed up the GPT with parted, but this shows what it asked the first time. fdisk output was the same all along

Please run the following command and attach the file:

It appears to have a protective mbr to me, but the partition table is just empty, so it looks like you somehow deleted your partitions.

Yes, it does. The installer (utopic, trysty) still says there is no OS and offers to wipe the machine which is not a cool option to do..

If you choose "something else" does it see the partitions correctly?

So if the bug isn't in parted where is it? It's still the same on utopic.

I think partman-auto is the component responsible for deciding that you have an existing windows install and offering the side-by-side option.

affects: parted (Ubuntu) → partman-auto (Ubuntu)
