Question Windows Disk Management showing my old boot drive having some strange partitions and Windows think they are on a different drive

[JuanMaren]

Hi,
I'm having some trouble with my disk management in Windows 11. A few months ago, I bought a new M.2 SSD from Patriot (Viper VPN100) and reinstalled Windows on it. I used to have it on an old SATA SSD from Corsair (Force GS 240GB). Now I've been updating BIOS, drivers etc. and the thing is that BIOS is showing the old SSD as being the boot drive and none other. I'm confused because it should be on the new SSD.
If you need any further info, I'll happily provide it.

Thank you so much for your response in advance.

During windows install process installer checks for existing bootloader partitions.
If existing bootloader is found, then no new bootloader is created.
Old bootloader is being used and additional boot entry is added to existing bootloader.
New drive doesn't get made bootable.

That's why, when installing windows on a new drive, you have to make sure only new drive is connected during install process.

In your screenshot bootloader is located on Disk 2 - 100MB EFI system partition.

Ah, ok. What do I do then? I don't wanna lose any data.
Thanks.

Do you plan on removing 250GB drive from system?
If no, then everything is fine, as is.

If you want to make your new 500GB drive bootable, then you have to create bootloader on it manually.

I don't plan on removing it, but I'd like to make that new one bootable and run Windows only on it.

You' re already running windows from new drive.
You're just using bootloader from old drive.

Alright and how do I move it to the new one? Sorry if my questions are dumb, but I'm not that experienced

Execute following from elevated command prompt. Regular command prompt will give error on last step.
If you get any errors, then stop immediately and show screenshot.

diskpart​

list disk​

select disk 4​

(select 476GB disk)​

list partition​

select partition 4​

(select 195GB partition)​

shrink desired=500​

create partition efi size=500​

format fs=fat32 quick​

assign letter=M​

exit​

bcdboot C:\windows /s M: /f UEFI​

If everything went ok, then boot into BIOS and change boot priority.
Set first boot device to Windows Boot Manager on 500GB drive.

Show latest screenshot from Disk Management.

Where there any errors, doing those commands?
Was the last message "Boot files created successfully"?

Is there something like "Hard Drive BBS priorities"in BIOS?
Try turning off secure boot.

I didn't find anything like what you said, but I changed CSM to other OS and the Secure Boot. I showed the other SSDs in the menu (in attachments) but when I chose the Viper it said to choose a proper Boot drive (attachment). Thanks

BTW - what is model name for the motherboard?

This is what it shows:

Syntax error in last command. Should be:

In one of your previous screenshots it clearly shows Intel Rapid Storage Technology being enabled and
sata drives being in RAID mode.

Sorry, didn't notice the RAID, so I disabled it and ran the prompt again and it showed the boot files being created successfully:

I restarted the PC, went to BIOS and the Viper was showing as Windows Boot Driver so I chose it. Now, how do I format the old SSD to get rid of all the system components?

Use diskpart clean method. This removes all partitioning and all data from the drive.
Make sure, you have no important data left on it (data you haven't backed up somewhere else).

diskpart​

list disk​

select disk x​

(select 223GB disk, replace x with appropriate number. Don't clean the wrong disk.)​

clean​

After that you can repurpose 223GB disk for something else.
Create single large partition and format/assign a drive letter.

I've successfully cleaned and reformated the SSD and everything is correct now.
Thank you so much for your help and take care!
