This still affects me on ubuntu-mate 19.10 amd64 also while selecting the option "erase disk" which only prompts you to select a "single disk" on which ubuntu will be installed even false summarizing that no other disks/partitions will be altered which is a lie! This happens in both UEFI and legacy bios mode installs.
With the Legacy BIOS install the damage could be worse since it will destroy MBR tables of any earlier SDA disk on which GRUB will install the bootloader resembling the old "Microsoft Windows XP installer" on which you'd better physically unplug any other disk on which you don't want the OS install to run. Searching for a launchpad bugreport for the legacy part anyone? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1396379 Title: installer uses first EFI system partition found even when directed otherwise To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1396379/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
