Comment (by kallisti5):
This is the final big GPT bug.
At this time, writing an Intel disk system over a GPT disk system results
in both disk system in place. (MBR at the front, GPT's backup header at
the end). GPT has a higher priority so it gets used.
Here is the result of a GPT disk system created, then an Intel/MBR disk
system created over-top of it:
{{{
$ gdisk test.img
GPT fdisk (gdisk) version 0.8.10
Partition table scan:
MBR: MBR only
BSD: not present
APM: not present
GPT: present
Found valid MBR and GPT. Which do you want to use?
1 - MBR
2 - GPT
3 - Create blank GPT
Your answer: 2
Using GPT and creating fresh protective MBR.
Command (? for help): v
No problems found. 204733 free sectors (100.0 MiB) available in 2
segments, the largest of which is 204727 (100.0 MiB) in size.
Command (? for help): p
Disk test.img: 204800 sectors, 100.0 MiB
Logical sector size: 512 bytes
Disk identifier (GUID): 82009838-FFFF-FFFF-3898-0082FFFFFFFF
Partition table holds up to 128 entries
First usable sector is 34, last usable sector is 204766
Partitions will be aligned on 2048-sector boundaries
Total free space is 204733 sectors (100.0 MiB)
Number Start (sector) End (sector) Size Code Name
1 40 67623 33.0 MiB FFFF
