I'm attempting to replace an existing Mint installation with Ubuntu on a UEFI system. The complication is that I'm dual-booting with Windows, and I'm very wary of messing that up in the process.
In the installer, I'm choosing to do "something else" as the installation type. I am then presented with the following (I've stitched multiple screens together to make this a bit easier to understand):
I'm unsure on exactly what I need to do here to ensure my Ubuntu replaces my Mint. I'm particularly concerned about the following:
- Will Grub show me only Ubuntu and remove the current Mint entry?
- The "Device for boot loader installation" has me concerned. Should I leave this as
/dev/sda
? - Do I need to manually delete the partitions currently used for Mint?
Can anyone tell me the exact procedure I should follow here?
