Windows 10: How to fix Operating System on new SSD?

Laptop given to me has Windows 7 Ultimate upgrade from Windows XP Pro. It has software including an older Microsoft Office. Replacing original old and slow yet functional HDD with a new SSD. Every time after successful system imaging onto SSD, regardless of number of successful startups prior, after a crash, restart, or shutdown, it displays either:Missing OS: Non-system disk or disk error current: I don't have the upgrade product key and OS media, Office product key, and original preinstalled OS media yet still have the Windows XP Pro 25-character product key. I'm tired of reimaging the SSD

Issues with installation of new MSATA SSD

Hello all, I recently received a new Kingston 240gb MSATA SSD (RMA replacement) for my Alienware 14 laptop. It's an SUV500MS/240G. I seem to be having a bit of a nightmare with getting it set up properly. So my intention was to set it up as the new boot drive and then have the 750GB SATA HDD that's already installed run as the secondary. After installing Windows 10 home edition via a USB drive, when entering the bios I noticed that the new SSD is listed under legacy drive in the boot options and not UEFI. In an attempt to correct this set the BIOS to only boot with UEFI and then rebooted with the installation USB drive and used disk part to clean the SSD and convert it from MBR to GPT and then reinstalled windows 10. The first attempt to reinstall seemed to get hung up and I had to repeat the process, the second attempt successfully installed and was able to boot into windows. If I go into system information, the BIOS mode is now listed as UEFI and not legacy, however the SSD still isn't listed in the BIOS as an option under UEFI boot devices. To make things even more annoying when I boot the laptop it now lists 3 different operating systems - I assume these are the one I installed in legacy, the failed one and the successful UEFI one. I read online that simply changing an SSD from MBR to GPT will not in fact dictate if the drive is seen as UEFI or legacy but instead it is based off of the type of bootloader it has installed. It goes on to say that to be UEFI it needs an EFI system partition and then lists steps to delete and replace the system partition. You may say well there is your answer but that leads me to the next step of the problem. When loading up disk management, what's listed as disk 1 is the new SSD and disk 0 is the old 750GB HDD. The 750GB drive has an associated system partition but the SSD does not even though it is the primary boot drive (C I attempted to use disk part again as the online post had suggested to create an efi partition on the SSD however disk part simply tells me that there is not enough usable space for this operation. Now that I have attempted to explain my problem I was wondering if anyone could offer up any sort of solution, my aims are to A) Add an efi partition to the SSD in the hope it will make the BIOS see it as a UEFI boot drive or if anyone simply has an alternate method to achieve this same goal that would also be appreciated. B) Remove the excess operating systems that are now listed on the laptop when booting If any additional information is required or further explanation is needed please don't hesitate to ask and I shall get back to you ASAP. Thanks Daniel Edit 1: It seems as if I have managed to remove the operating systems that were listing when starting the laptop. I used msconfig to do this, I am hoping this has actually removed it and not just hidden it, if anyone could let me know if this was the correct route to solve this issue that would be great.
