Unfortunately, that Disk Utility method does not work for the newest Mac OS X 10.9 (Mavericks) that was released as a free download on Tuesday. So, if you wanted a backup install disc in case something went wrong, or in case you wanted to install Mac OS X on your computer without signing into the Mac App Store, you'd have to create a bootable DVD or USB drive yourself using the InstallESD.dmg, which was an easy process using Disk Utility. Refer to the following message from Ubuntu's mailing list if you want to learn more.There hasn't been any physical installation DVDs available for Mac operating systems since Snow Leopard (10.6), with Lion (10.7) and Mountain Lion (10.8) both available via the Mac App Store as downloads only. Warning: The driver descriptor says the physical block size is 2048 bytes, but Linux says it is 512 bytes.Īll these warnings are safe to ignore, and your drive should be able to boot without any problems. Try making a fresh table, and using Parted's rescue feature to recover partitions. Is this a GPT partition table? Both the primary and backup GPT tables are corrupt. Or perhaps you deleted the GPT table, and are now using an msdos partition table. Perhaps it was corrupted - possibly by a program that doesn't understand GPT partition tables. However, it does not have a valid fake msdos partition table, as it should. dev/xxx contains GPT signatures, indicating that it has a GPT table. 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.Ī consequence of this enhancement is that some programs, like parted get confused about the drive's format and partition table, printing warnings such as:
