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. Although it's a bit annoying that I wasn't smart enough to do it with a mac, I'll get over it.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: This approach worked, and I got a UEFI bootable usb stick, so thanks for your link. iso file I originally tried to copy with dd. Next I tried with the Rufus tool, which got the job done using the same.

I negotiated for some computing time on teh wife's pc laptop, and for some reason the microsoft Media Creation Tool (the first option in your link) failed with "Something Happened 0x80070002 – 0x20016" error code (internets said you could try logging in as admin etc. Doesn't dd work in such a way that it directly writes the input (the dvd image) to the device, and the file system of the image will be copied over what ever the usb stick has?Īnyway, I now have a bootable usb media. If someone knows the details of this, I'd be happy to learn more.Īlso I don't believe that formatting matters at all. I'm not sure, but I think that all computers are not capable of booting an USB stick that has a file system of an optical media.

Which is what I did and it produced the file system I pasted up there.
