Solved!

SSD will only allow UEFI boot and not show up as a Legacy Boot option?.

HP Recommended

Hello,

 

My comany is purchasing HP EliteDesk 800 G2, some comes with HDD and some with SSD.

We deploy Windows 7 x64 using SCCM using legacy boot.

 

On a machine with HDD installed I can configure the boot options to use legacy boot, but when I replace the disk to a SSD drive the only boot option for this drive is UEFI.

That causes the deployment to fail because the drive need to be partitioned as GPT.

On the other hand, if I disable legacy boot, PXE boot to UEFI and partition the disk as GPT, after the image deployment the disk is unable to boot with 0xc000000d error (I imagine the cause is Windows 7 support becuase it does work on Windows 8.1).

 

Bottom line, I can install Windows 7 on a HP EliteDesk 800 G2 only if legacy boot is enabled and I partition the disk as UEFI.

Is there any way of forcing the SSD to boot as legacy and not UEFI?

Is this issue caused by the workstation or is it enforced by the SSD?

 

Thanks

alexsunny

Greetings,

Welcome to the forum.

I am not a HP employee.

 

Maybe the following Intel Technology Brief may provide some insight (Link).

 

My take on this is you need a supported operating system. W7 needs drivers. You need the BIOS UEFI boot option active and GPT to boot to an NVME M.2 drive. I have run W7 on an NVME M.2 drive, as the boot device, using the previous parameters.

 

It appears a Legacy W7 setup using MBR is not going to work when using a NVME drive as a boot device.
