Make sure when you want to install in uefi/gpt, the install media is booted in uefi.
It is possible that your install media is booted in bios-legacy not uefi.
But I am surprised installer changed gpt partitioning to msdos partitioning.
No installer I know does that. It may be that it is still gpt partitioning but with a bios-legacy boot.
Can you provide output of "sudo parted -l".
Oh, another thing. Currently installing Bodhi to uefi/gpt is still a struggle. There are workarounds and if you have another linux OS in the uefi/gpt system, then it is much easier to convert the installation to it. See http://forums.bodhil...urther details.Go to the full post
