I have SSD and HDD on my laptop. I made partitioned the SSD and installed Windows 10 and Ubuntu 18 in SSD (dual boot).
My SSD size is only 250GB (both OS installed here) and HDD size is 1TB.
Now I want to move Windows 10 (not reinstalled, just move) to a HDD and keep existing Ubuntu 18 own the SSD.
What is the easiest way for this without data loss?
sudo update-grub
. Do not touch the ESP (EFI System Partition).
