Bug 394639

When creating or editing a partition's properties, KDE Partition Manager does not display MBR partition type IDs or GPT partition type GUIDs. I assume that this probably gets determined for new partitions based on the various settings (filesystem, "flags", etc.) but the flags don't represent a realistic picture of the partition table. IMO,
- the flags section should disappear and be replaced with
a drop-down list that allows the user to choose the partition type (https://en.wikipedia.org/wiki/Partition_type). Note that this applies to both MBR and GPT; the only difference is that GPT uses long GUID codes and MBR uses single-byte codes. This would be _in addition_ to the Filesystem drop-down.
- There should be a _separate_ checkbox that toggles the "bootable partition" bit on GPT (search "Legacy BIOS bootable" on the Wikipedia GPT page for more info) and the equivalent bit on MBR.

Reasoning:
- Checkboxes (as shown in the flags option) do not make sense when they are mutually exclusive (because a partition can only be one partition type).
- The flags-based design makes it unclear what "boot" does, since it behaves differently on GPT and MBR: on GPT, it does the same as "esp", which changes the partition type GUID in the partition table to C12A7328-F81F-11D2-BA4B-00A0C93EC93B. On MBR, I assume that it flips bit 7 in byte offset 0 of the partition entry. But it's unclear whether it does the equivalent operation on GPT, which, like MBR has a separate "bootable" bit in addition to partition type GUID.
- The "flags" imply that partition tables have such a structure as "flags," which is not the case, at least for GPT and MBR.
