I solved the issue by doing the following: - boot the old system (from the 256GB SSD) - attach the 2TB SSD via USB - use Macrium Reflect to clone the 266GB SSD onto the 2TB SSD - use mbr2gpt (don't forget to specify disk:X in the args!!! In my case X=1) to convert the 2TB disk from MRB to GPT - place the 2TB disk into the new system - boot -> Win10 boots (happy smile on my face) - use Minitool Partition Wizard to resize the system partition on the 2TB SSD That was... Well, it's done now... Thanks -a-

https://scottiestech.info/2021/04/13/why-cant-i-enable-csm-on-my-new-motherboard/ Turns out you cannot enable csm on 500 series motherboards when using only the igpu. The igpu doesn't support legacy boot

I tried to to the following: - fresh install of Win10 on the 2TB drive (on the new system) - boot on the old system (on the 256GB drive) - attach the 2TB drive via USB to the old system - use Macrium Reflect to: * erase all partitions but the 1st one (EFI?) on the 2TB drive * copy the system partition from the 256GB drive onto the 2TB drive - put the 2TB drive back into the new system - boot -> nothing (drive detected but not available as a boot option. I couldn't find any way to setup Secure boot (or disable it) in a way that

I cannot find any way to enable legacy boot (or CSM) on this board :(

Even when I did this, only the Win10 USB installer was present as a boot option. However, Windows was able to see the drive (just like the BIOS is, although it doesn't offer it as a boot option) and once the OS was installed "Windows boot manager" was present in the boot options in the BIOS, allowing to boot from the SSD.

Is the SSD brand new? Or was it retrieved from a previous rig? If it's a used SSD, you might be experiencing the same issue as me. Best, -a-

"Boot Sector (MBR/GPT) Recovery Policy Allows you to select the Boot Sector Policy. Configuration options: [Auto Recovery] [Local User Control] [Auto Recovery] : Follows UEFI Rule." I had to set it to Auto Recovery

https://dlcdnets.asus.com/pub/ASUS/mb/13MANUAL/PRIME_PRO_TUF_GAMING_Intel_500_Series_BIOS_EM_WEB_EN.pdf I found this: "Due to Microsoft Secure Boot regulations, ensure the Microsoft signed UEFI driver is contained in the plugged PCI-E based storage including M.2 SSD before setting [Launch CSM] to [Disabled]. Otherwise, the PCI-E based storages will be only available for the data drive usage. " It sounds like what I am experiencing: the SSD is detected but cannot be used for boot (only for data?). CSM is disabled and I cannot enable it. I guess I should look into secure bo

This drive works well on the z170-a (but cannot be used as boot device on the H570). I guess that means the boot sectors are OK, right? I'm a bit confused now...

I was recently told on this forum about Macrium Reflect Free and I was successful cloning M.2 NVMe SSDs with it. It's user friendly and easy to use. Then I could move and resize the partitions on the new drive with Minitool Partition Wizard. Also very easy and straightforward. I'm not sure I could have done everything with Macrium but at least it wasn't super intuitive to me when I was trying to play around with the partitions on the new SSD

I need to look into that but I'm not sure it would work. The thing is I can no longer install the app I need on a fresh system. The app requires a key (serial number) and this key can no longer be activated (activation was limited in time). IDK if copying user data and appdata would solve this. I could try, though... Let's call that plan B. Or C...

Thanks @SupaKomputa but I'm not sure what you are referring to. Maybe you can elaborate. Or I can use Google to educate myself. Thanks -a-

Thanks @Idle_Wild for the heads up. I cannot remember why I used this M.2 PCIe AHCI SSD back then. Probably because it was laying around and I had no other use for it. Anyway, even if my z170-a can manage NVMe SSDs, I'm not sure how this could help me. What should I do now (that I haven't tried already)? Thanks a lot -a-

I guess that's my issue then. Idk how to enable legacy boot. Cannot find the option in the BIOS. And as I mentionned, it looks like CSM cannot be enabled for some reason.

Hey @SupaKomputa Could you please elaborate? I don't get what you mean. This could be useful to me as well I guess... Tx -a-
