I'm trying to install Ubuntu on a Mac, but I can't get it to boot with default mac bootloader or rEFI. It shows up as "Windows" On the mac bootloader and shows up as "Linux" on rEFI.

I'm not sure where should I install the bootloader to during installation.

Here's my partition table:

sda : Hard drive manufacturer name

sda0: Mac partition

sda1:

 ...

sda4: SWAP

sda5: Ubuntu

And I have installed the bootloader on sda5. Should I install it on sda instead? I'm afraid this will replace the default Mac OS X bootloader and I won't be able to go into the Mac side again.

Any help will be greatly appreciated. Thank you.
