Windows 10: Windows boot manager or SSD?

I have installed a new SSD and installed windows 11 on it using a bootable usb. When I go into the bios settings I see my SSD ZEBSD26 in legacy boot mode and Windows Boot Manager in UEFI boot mode. When I boot from the SSD in legacy boot, I get this error "The selected boot device failed. Press any key to reboot" but when I boot from the Windows Boot Manager, everything works fine and I get into windows. In my previous HDD I could select the HDD name in legacy boot and boot into windows 11. I am unsure that should I boot from Windows Boot Manager everytime or SSD.

Cant boot from SSD, Windows Boot Manager

Hello FernandoSuarez,

I am Antonio, a Microsoft Community independent advisor and a Windows 10 user like you. I hope I can help you on your concern.

Was the HDD reformatted when you make it as the secondary drive? or not?

Please try these steps

Note: Connect both your SSD and HDD. SSD will be your first boot.

1. When you login in windows, go to run and type msconfig

2. In System Configuration screen, go to Boot tab

3. If you see multiple OS in the list, select the OS on the SSD

4.Click Set as Default button.

5. Restart your PC and check.

You're response is highly appreciated. Please let me know if you need further assistance.

Sincerely,

Antonio

 

Windows boot manager

There could be some system conflict triggered after the said changes. To help you with your concern, we suggest that you perform a clean boot. A
clean boot is performed to start Windows by using a minimal set of drivers and startup programs. This will help to determine what is causing the issue on the Windows boot manager. To do this, click on this
link and scroll down to the
How to determine what is causing the problem by performing a clean boot section then follow the steps listed..

Note: If the installation is successful and the issue has been resolved. Please go through the section “How to reset the computer to start as usual” to reset your computer to the normal startup.

Let us know how it goes after performing the suggested steps.

 

Switching Windows Boot Manager from HDD to SSD

(1) It is the EFI partition that holds the boot files including the BCD (Boot Configuration Data). The BCD tells the boot process which Windows partition to boot to. It looks like you set the BIOS correctly to boot using EFI (& its BCD) that is on the SSD. However, that is a clone of EFI on the HDD -- which loads the Windows partition that is on the HDD. You need to alter the SSD's BCD to boot to the Windows partition that is on the SSD. Let's see your BCD...

(a) Type CMD into Search, & click Run as Administrator.

(b) Enter the following commands...

BCDEdit /Enum All <<<Show the BCD

DiskPart <<<Enter DiskPart

List Vol <<<List the Volumes

Select Disk 0 <<<Focus on the HDD

List Part <<<List its partitions

Select Disk 1 <<<Focus on the SSD

List Part <<<List its partitions

Exit <<<Exit DiskPart

Use Ctrl-A & Ctrl-C to copy, then post it to us. We can adjust it manually.

(2) It might be as Paloma suggests, that disconnecting the HDD will cause the BCD (on the SSD) to self-adjust. Windows might do an automatic Startup Repair. But I hope it also gets the Recovery partition right.

(3) I guess you want that D: partition. So, after all is well with the SSD, you may plug the HDD back in. But it will be best to delete its EFI, Windows & Recovery partitions. Just keep D:.
