docs: ubuntu iso's hybrid format and parted warnings (#585)
Document that `parted` warnings about invalid GPT and physical block size issues can be safely ignored as they are a consequence of "hybrid iso's". Fixes: https://github.com/resin-io/etcher/issues/312 Signed-off-by: Juan Cruz Viotti <jviottidc@gmail.com>

Flashing Ubuntu ISOs
|
||||
--------------------
|
||||
|
||||
Ubuntu images (and potentially some other related GNU/Linux distributions) have
|
||||
a peculiar format that allows the image to boot without any further
|
||||
modification from both CDs and USB drives.
|
||||
|
||||
A consequence of this enhancement is that some programs, like `parted` get
|
||||
confused about the drive's format and partition table, printing warnings such
|
||||
as:
|
||||
|
||||
> /dev/xxx contains GPT signatures, indicating that it has a GPT table.
|
||||
> However, it does not have a valid fake msdos partition table, as it should.
|
||||
> Perhaps it was corrupted -- possibly by a program that doesn't understand GPT
|
||||
> partition tables. Or perhaps you deleted the GPT table, and are now using an
|
||||
> msdos partition table. Is this a GPT partition table? Both the primary and
|
||||
> backup GPT tables are corrupt. Try making a fresh table, and using Parted's
|
||||
> rescue feature to recover partitions.
|
||||
|
||||
***
|
||||
|
||||
> Warning: The driver descriptor says the physical block size is 2048 bytes,
|
||||
> but Linux says it is 512 bytes.
|
||||
|
||||
All these warnings are **safe to ignore**, and your drive should be able to
|
||||
boot without any problems.
