About a week ago I got a new SSD and transferred my windows 11 install to it. Everything went smoothly and a few days later I left for a week for Christmas. Turned my computer off when I left obviously.
When I got back and booted my PC again I noticed it had booted Windows off my old install on my other SSD. And when I went to the BIOS, the boot option for my new SSD is no longer there. I can see the drive is still activated, I've still got files on it and I'm pretty sure all the necessary files for Windows are still on there.
So this has just kinda happened out of nowhere and as a result I have no idea what the issue is.

Anyone know how I can fix this?

Hello and welcome to the forum. I don't have enough information to give a specific solution since you have neither completed your system specs in your forum profile nor given info about what kind of old drive you had and what you replaced it with. Also you say you "transferred" to the new drive. Did you clone or restore an image to this drive. Did you put the replacement drive into the same slot as the old one was in?

As a general answer, try bringing up boot menu at startup, either f12, f9, or esc depending on brand of computer. Usually f12 will do it but HP uses f9, some brands use esc. Does your new drive appear in this one-time boot menu? If so, select appropiate drive OR go into bios and change boot order for the change to be permanent..

    Still assembled, still runs. Haven't turned it on for 13 years?
About a week ago I got a new SSD and transferred my windows 11 install to it.
Indicate if this was cloning, restoring an image, dual booting, etc.

When I got back and booted my PC again I noticed it had booted Windows off my old install on my other SSD.
What was the old install?

And when I went to the BIOS, the boot option for my new SSD is no longer there. I can see the drive is still activated, I've still got files on it and I'm pretty sure all the necessary files for Windows are still on there.
What is meant by activated?


Can you move the disk drive to an empty bay of another computer or to a hardware enclosure for testing?

Thanks for the quick reply.
The old drive is a SATA and the new one is an NVME. The SATA was not removed or reseated when I installed the NVME.
I cloned the install to the NVME drive using Partition Wizard.

I checked and the NVME drive isn't appearing in the boot menu either.
I'm not sure what other specs you may need other than my motherboard which is a Gigabyte Arous Z590 Elite AX.

Here you go.
'Sata SSD' is the old drive and 'Boot Drive (NVME)' is the new one.

zbook is one of our resident experts in such matters. He will lead you in finding out why the drive is not showing up in boot menu. Just follow his instructions. Just FYI, I have noticed several posts recently similar to yours where the new drive ended up being bad. Hope you have better luck.

The install was cloned.
The old install is exactly the same as the one on the new drive. I only left for Christmas a few days after I cloned it so they can't be that different.
By "activated" I just mean the drive is still working properly. My volumes are still set up and I can still store and read from it.
I can't move new drive to another computer unfortunately. It's an NVME drive and I don't have any other computers that support it.

What exactly is the reason for running that command into cmd? I've done it and I'll paste the results below but I'm not sure what I'm looking for.

when I went to the BIOS, the boot option for my new SSD is no longer there.

bios should normally find \EFI\MICROSOFT\BOOT\BOOTMGFW.EFI on efi system partitions.

There might be a way of adding it in your bios settings.

Alternatively you can use something like this to add the boot file from within windows

diskgenius-set-uefi1.jpg

click ADD

diskgenius-set-uefi2.jpg


this window will pop up, then select the other esp partition in the dropdown

diskgenius-set-uefi3.jpg

then EFI folder ( you won't have all those other folders on your esp partition, that is my stuff )

diskgenius-set-uefi4.jpg


inside EFI folder is the microsoft folder

diskgenius-set-uefi5.jpg

inside microsoft folder is boot folder

diskgenius-set-uefi6.jpg


inside boot folder, scroll down to the little feller

diskgenius-set-uefi7.jpg

Which is partition H that your bcdedit refers to ?

bios should normally find \EFI\MICROSOFT\BOOT\BOOTMGFW.EFI on efi system partition of disk2.

There might be a way of adding it in your bios settings.

Alternatively you can use something like this to add the boot file from within windows

click ADD

this window will pop up, then select the other esp partition in the dropdown ( you will be looking for the esp partition on disk2 )

then EFI folder ( you won't have all those other folders on your esp partition, that is my stuff )

inside EFI folder is the microsoft folder

View attachment 48503

inside microsoft folder is boot folder

inside boot folder, scroll down to the little feller

This fixed it!

Disk Genius clearly shows a second Windows Boot Manager entry for the new drive so I have no idea why it still won't show in the BIOS, but creating a new one like you showed seems to have worked. I even shut down my PC a couple of times to see if it continues to stay functional and it looks like it does.

Thank you so much.
