GPT partition table warning message during install of ubuntu

rated 0 times [ 1] [ 0] / answers: 1 / hits: 70078 / 1 Year ago, mon, may 8, 2023, 3:22:13

/dev/sda contains GPT signatures indicating that it has a GPT table. However, it has a fake msdos partition table as it should. Perhaps it was corrupted? Is this a GPT partition table?

So, that's the error message and this is during my first OS install of Ubuntu.
Can close the message box. Can't click yes and can't click no.
What do I do?

I've seen a similar problem on my disk when I had a leftover partition from my windows 7 system. Went back to windows 7, and took all the partitions off using disk manager.

Also, make sure the disk is not "dynamic" in disk manager.

After that, I was able to do a clean install of ubuntu 12.1o :)

In case you don't have a system running windows 7, you can boot with a windows 7 dvd and run setup. Choose "advanced" when you get to choosing partition for the installation, and erase all partitions there.
