I attempted to install the latest version of Linux Ubuntu Studio, with previously installed Ubuntu 14.04. Installation procedure went fine, it was only at the finish, when something collapsed, I failed to write down or take a picture of what the problem was.
Now, when i try to boot from USB, it stucks on this error
GNU GRUB Version 2.02~ beta 2-9
Minimal BASH-like line editing is supported. For the first word, TAB
lists possible command completions. Anywhere else TAB lists possible
device or file completions.
grub>_
None of the options in Boot menu are not successfull. Please help, thank you!

I'll refer to that prompt as a 'grub rescue' crash. You can use the grub commands with steps provided in this answer: https://unix.stackexchange.com/a/148042/81664
I have used those steps in the past and it works. However, I usually use a different set of steps that also works. The steps below that I'm using involves updating grub and reinstalling grub.
The reinstalling will incidentally repair and problem glitches in the original install that is causing the crash. The update with find all installed OSes and add them to the boot menu.
You can most likely remedy this by manually installing grub on your desired HD.
Boot to a live try Ubuntu session, then run the following at a terminal prompt:
After you have performed the manual steps be sure to set your computer bios to have your desired boot drive as the default boot device.
