Legacy partitions on Intel NUC NUC5i7RYB

[Bannockburn]

I am not sure if I have selected the correct sections for this question. Can someone please clarify if the Intel NUC NUC5i7RYB Is able to detect legacy partitions that were created using another computer.

Essentially, I am trying to transfer an SSD with windows 10 installed from a an older PC using legacy bios to an intel NUC5i7RYB.

In the bios of the NUC, the partitions of the SSD are recognized under the UEFI section and not in the legacy section and do not boot (I get a no boot drive error).

I have tried a number of things such as resetting the bios to factory default settings, updating the bias and disabling UEFI. I also tried using a mechanical HDD with Windows 10 installed (also previously used with a legacy bios system and I got the same result.

I did, however, have success when I transferred an SSD with Windows 11 installed on it from another PC to the NUC was able to boot with no problems.

I am wondering if anyone has had a similar issue as l have above is it even possible to use legacy partitions on this model NUC? I'd appreciate any help anyone is going to offer.

Is this an NVMe SSD? UEFI boot (and GPT partitioning) is a requirement for NVMe.

Hi, thank you very much for your reply. I am not using an NVMe SSD. I am using a standard SSD,a Crucial BX500

In BIOS Setup, in the Boot tab, is Legacy Boot checkmarked?

Hi,

I have a NUC5i7RYB with 128 Gb M.2 SSD and have exactly the same problem. Anyone knows how to fix this ?

@Bannockburn, any response to my query? Is Legacy Boot checkmarked?

@Paudio25, What kind of SSD is this, how is it formatted (i.e., GPT or MBR)?

A common cause for this issue is that the Boot Sector on the drive has been corrupted (or was never written, a common problem with many cloning tools) and needs to be restored. One way to restore the contents is booting from a Windows Recovery disk, opening a command line and doing command "bootrec /fixmbr". You could also use the "Fix Boot Problems" capability in the Macrium Rescue disk.

Hope this helps,

I’ve managed to solve the problem, found the Solutions on Reddit.

- Add a 2nd USB thumb drive in the front of the NUC, it does has to be a bootable drive.

- Boot and press F2 to get in Bios, make sure you can see a boot device under Legacy. Press F10 to save & exit and reboot.

- At the start up screen press F10 again to select the boot menu

- Select one of the USB drive from the last 2 lines you want boot with.

I hope this help another users.

Apology for my bad English.
