I have a fresh Windows 10 install on an SSD (sda). Now I want to add a second SSD (sdb) and install Ubuntu on it in such a way that there will be a separate EFI partition on sdb with the Ubuntu bootloader (GRUB) installed there and NOT on the EFI partition on sda. How do I accomplish this? I know there is an option to select "Device for bootloader installation" during the Ubuntu installation but it has been reported that this selection is ignored due to a bug: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1396379
Also there is this peculiar guide on how to install Windows and Ubuntu on spearate disks: https://askubuntu.com/a/1126970/1158552
It somehow ends with the Ubuntu bootloader being installed in both EFI partitions on the two separate disks... How is this even possible?
Kind regards
