[Bug 1909161] [NEW] ubuntu 20.04.1 LTS installer failed during setting up a dual-boot ubuntu on windows 10

[Takumi Matsuzawa]

Public bug reported:

I attempted to set up a dual-boot Ubuntu with Windows 10.

Motherboard: MSI x570 Ace
CPU: AMD Ryzen 3950
Drive: Western Digital M.2. 2280, 1TB

I first installed Windows 10, and allocated 500GB for Ubuntu install.
Using a bootable USB, I attempted to install Ubuntu to this allocated
space. The desired partition scheme was something like

/boot 500MB
/usr 7GB
/root 8GB
/swap 8GB
/tmp 1GB
/var 1GB
/ ~475GB (the rest)

This is my first time setting up a dual-boot system, and I'd be eager to
know what went wrong during the installation process.
