Dual boot with cloned disk from previous laptop
I have a new laptop with a M2.SSD 256 GB running windows 10. The laptop, HP Proobook 470 G5, has a bay where I wish to mount the SSD (2TB) which I recently have successfully cloned from a HDD (2TB), which now are running on the older laptop.
I would like to just move the SSD from the old laptop, which already have a dual boot system, with two different partitions, the main running Windows 7 Ultimate, and the second Windows 10 - and then be able to choose to boot the preinstalled windows 10 on the M2.SSD, or one of the two bootable systems on the second SSD. Is this possible ?
It is not an option to create a partition on the M2.SSD and clone the old system to that, since the disk already contains approx 800 GB - i.e. 3 times more than the total available space on the M2.SSD.
As a test, I tried to mount the old HDD in the bay, then selected the boot order to first boot from the HDD, but the system reported "no bootable media found". I wonder if the task is complicated by the new HP running an UEFI system, while the old laptop is an old (6 years) BIOS-based system (?).
I realize that this maybe not is strictly a "cloning" issue, but does anyone in this forum have any idea if the mission is possible, and if so, how to accomplish the task without reinstalling either of the OS'es. Any suggestions will be highly appreciated.

Roar,
Steve outlined a solid plan for you here, I think you will run into issue with Windows 7 because as far as I know conversion from an MBR to UEFI/GPT is not possible for Windows 7. Windows 7 if clean installed on a UEFI booted system will work but I have yet to see a conversion succeed.

En réponse à Roar, welcome to these User… par truwrikodrorow…

Thank you very much, Steve; for your interest and effort in this matter. This will of course be very interesting to try out, and sure it will take some time to complete the steps ( -especially since I'm in the auditing and accounting profession and have a lot of deadlines to meet this and next month). So it may take a while before I will be able to report how your suggestions works for this case; but I'm very grateful for your help so far.
In the mean time I have tested if it is possible to do a clean new windows 7 install on a separate partition on the SSD, but I ran into problems related tot the NVME drivers for the XG5 (Toshiba OCZ ) M2.SSD. It seems that there is no official released drivers; at least not yet, probably due to that this is an OEM product for the HP probook, so I have note succeeded even in this first step. I tried both installing directly from (external) DVD, and several tests making a bootable USB stick (using Rufus www.rufus.akeo.ic ) , including replacing files as described by Microsoft hotfixes for NVME and win7 (KB Article Numbers: 3087873 and 2990941), .
My challenge is that the windows 7 installation works fine for me in itself, with a huge number of installed programs and applications with my own settings and preferences, which will take "months" to regain on a new windows 10 from scratch - and still I definitely prefer win7 as my 'production environment' even if I'm also using a couple of other desktop pc's with. win10.
I will update this thread when I'm doing any progress, so far, again thanks a lot for trying to help!

Roar,
I wouldn't worry much about the driver for the Toshiba drive. The NVMe driver you read about is actually an Intel driver for the Disk Controller installed in the PC. Without the proper driver Windows 7 cannot locate the drive due to Windows 7 lacking native support for NVMe devices. The Microsoft HotFix addresses the issue and the result is that with the Fix the Windows installer will locate the drive and install Win 7 to it.

Enchantech, Thank you for your feedback. However, even when following the MS description for applying the hotfixes properly, the installation still halts, and asks for the NMVe drivers, with the option to "Load driver" - - but I'm not able to find how / where this drivers should be found. Any suggestions where to look, how to find out if the hotfixes really have been applied ? - or what to do next.
Obviously it have to be an issue here. I found a site where this is discussed - and link to different drivers ( https://www.win-raid.com/t29f25-Recommended-AHCI-RAID-and-NVMe-Drivers…) but this do not include a signed OCZ driver for XG5, only for XG3. I tried to download anyway, extracted to a folder on the installation USB. The drivers are then found, but reports 'not applicable for my drive'. I'm still stuck ...

The win-raid site drivers are top notch. I have used them myself with good results. Under the Toshiba drivers you will see mod+signed drivers. These are modded and digitally signed by the owner of the site. They show to support your drive. I would give them a try. Extract the contents of the download and place them all on a spare flash drive. When asked to add drivers during install point to the flash drive. It should work.
