Clean install of windows 11 on SSD (current OS on HDD)

I am planing to install a SSD in my laptop, which already has HDD. laptop support SSD and HDD together. The currest OS on the HDD and i want to do a fresh install on the SSD, Please can anyone write a step by step guide on what to do, i am not confident on this.

 

OS on new SSD, keep existing data on HDD and use as external drive

Hi,

use steps you suggested, there should be no problem.

Just replace HDD with SSD first then run installation. Do not forget to remove Windows files from HDD after the end of a process.

 

Cloned OS to SSD want to delete old OS on hdd

Not sure if this was answered(cant find 1) but recently cloned windows 10 from HDD to SSD. My HDD was setup as GPT and the partition was setup with the OS as almost the full 1tb size. I had and currently have alot of used space that i dont wanna lose if
it can be avoided. The whole cloning process was a pain having to move stuff to the ssd then partition the empty space on hdd the move stuff to the new partition until I had less than 200g with the OS still there so I can clone it onto ssd after cleaning
it. Os works fine(windows loads sooo much faster) old hdd works fine but wanna get rid of the old os on hdd without deleting anything else? Sorry so long and sadly I merged the partitions back to 1.
