The first SDD is running an encrypted Ubuntu install. I was unable to get dual boot Windows 10 alongside an encrypted Ubuntu install (I can with unencrypted Ubuntu install). Not the current issue I am looking to resolve.
I have a second SSD lying around, on which I wanted to install Win10 on it. I removed the first SSD from the laptop and installed the second SSD. However, the laptop does not boot the new SSD under UEFI. As such, I am unable to install Windows 10 on the second SSD. When I turn the computer on, it presents a grey screen and suggests to turn off the computer.
Usually, under legacy BIOS you could swap hard drives with different OS's and it would work.
Is there a limitation on swapping the SSDs under UEFI? Is there a solution to this?
@WAWood Thanks for the pointers. Yes, you are correct the second SSD is blank. I am trying to install Win10 on with a Win10 USB install media.
Follow up questions:
I have an external enclosure for the SSD that I can connect to my laptop for formatting the SSD to GPT. How do I format the SSD to GPT under Ubuntu/windows? When I had installed Ubuntu in UEFI mode I did not have to perform the GPT format (the first SSD was blank as well).
I am assuming the boot loader files will be installed on the second SSD during the win 10 installation process.
How do I ensure that the Win10 USB install media I have is compatible with UEFI mode? I have used the same media in BIOS Legacy mode to install Windows on the same laptop before.
