Can I replace MacOS with Ubuntu but keep my Windows partition?

[lightbluejordan]

I own a mid 2009 Macbook 5.2 with upgraded RAM of 6GB and an upgraded hard drive of 1TB.

I was originally interested in triple booting it, however, I already have it double booted with High Sierra and I just added Windows 8.1 Pro, and I don't feel like I wanna do that again right now. (Not that it's hard to do or that I don't enjoy an extraneous project- it may end up being what I gotta do.)

Would I be able to keep my windows partition if I replaced my MacOS with Ubuntu? Would everything function OK? I have my old hard drive that contains all my old MacOs stuff, so if I decided I wanted to go back to Mac it wouldn't be a problem. I usually do a clean install using dosdude1's High Sierra patch anyway.

You would probably need to come up with another boot manager since once you install Ubuntu its boot loader (GRUB) will overwrite the EFI partition and destroy Boot Camp. Make sure you back everything up first.

But grub can boot Windows so it may find it and add it to its menu. I really don’t know what would happen.

Thanks for the response, but I never used bootcamp in the first place to do the dual boot. Bootcamp doesn't support anything past windows 7 on that computer because it's so old so I just did it manually by splitting and formatting my hard drive.

Nonetheless, my computer has Linux Mint now.
