I have 2 drives installed in my desktop.
- 1TB NVMe (shows up as /dev/nvme0n)
- 2TB SSD (shows up as /dev/sda)
The NVMe has Windows 10 installed, and later had Ubuntu 20.04 installed alongside it.
I want to clean install Ubuntu 20.04 again on the 2TB, and wipe all traces of Ubuntu from the NVMe. (including bootloader entries and entries that would show up on my BIOS)
So I tried installing Ubuntu using "Something Else" when partitioning. I created a GPT table on the SSD, created a 500MB EFI partition, and a 128GB ext4 mounted at
However, when I reboot and hit F12 to bring up my boot selection, it shows
- Windows bootloader (ADATA) <--- (ADATA is the NVMe)
- adata (ubuntu) <--- (old ubuntu installation, which is still installed)
- WD SSD <--- (the new SSD)
- Samsung USB partition 2 <--- (Ventoy bootable USB, how I installed Ubuntu both times)
Choosing the WD SSD, my screen goes black for a second, then it goes back into the boot menu again, as if it failed to boot.
During installation, I've tried installing the bootloader to
/dev/sda1 (efi), and
/dev/sda2 (root), but none have worked.
Checking GParted (from the Ubuntu live USB), it shows that I have 2 partitions
How do I properly dual boot ubuntu in this situation? And is it possible to fix this without having to reinstall Ubuntu entirely?
