Dual Boot Windows 10 and Ubuntu 18.04 on separated SSD

This article mainly takes GPT + UEFI as example

Windows 10

Create bootable USB driver

When I installed Win 10, I used Microsoft official tool named MediaCreationTool to create bootable USB driver without ISO file. But now when I am writing this blog, I cannot find this on Microsoft’s official website any more. Instead, Microsoft only provides ISO file for download.

Therefore, now we have two options:

  • Use MediaCreationTool
    1. Download MediaCreationTool from 3rd party
    2. Create bootable USB driver following this tool’s instruction.
  • Use Rufus
    1. Download Rufus, a tool to create bootable USB driver
    2. Download Windows 10 ISO file
    3. Create bootable USB driver with Rufus, just make sure that Partition scheme is GPT and Target system is UEFI.

Install

Ubuntu 18.04

Create bootable USB driver

  1. Download Ubuntu 18.04 ISO file
  2. Create bootable USB driver with Rufus, as same as before except using Ubuntu 18.04 ISO file.

Install

Install Ubuntu alongside Windows Boot Manager, where the EFI patition located.

MBR + BIOS

All the same as GPT + UEFI beside these few points:

  1. When creating bootable USB driver, make sure both Windows 10 and Ubuntu 18.04 select MBR + BIOS. In other word, no matter what you want to use, GPT + UEFI or MBR + BIOS, just make sure both system have consistent Partition scheme + Target system.
  2. When installing Ubuntu 18.04, there would be no black screen with options but the same as single boot.
