/dev/sda 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?
So when I try to install ubuntu I get a whole TB of unallocated disk. However I can see the 2 partitions mounted on ubuntu when I run "try ubuntu" I've created the ntfs partition on /dev/sda3 in an effort to fix the GUID table without success.
Is there any way to fix this so I can install ubuntu on /dev/sda3?
