I have installed a p310 Gen4 NVMe 2280 M. SSD (1 Terabyte) from the original 128 Gigabyte C: Drive.

Hi

Can you be more specific as to which drive is C:, its capacity and any OS installed on it?

Ditto for D:?

Which drive is the BIOS pointing at as the actual boot drive.

Make Model and OS please.

C drive is the SSD space on the Dell Inspiron 15 3000 (mine is 3593). It came with Windows 10 on the small 128 Gigabyte SSD drive. It also has a larger (2.5 inch) HDD drive. It came with 1 Terabyte size.

After filling my 128 Gigabyte SSD C drive almost two years ago, constantly moving and deleting what I could to my 1 terabyte D drive, I finally bought the new P310 Crucial GenR NVMe 2280 M.2 SSD. 

After restoring my C drive image, it also did something to my 1 terabyte D drive. Fortunately I also imaged my D drive right after I imaged my C drive. 

Windows loaded slow with the new SD card in and I then had two screens to choose Windows 10. Only  the first (default) actually had the Windows 10 and booted.

I was able to go into msconfig and remove the second Windows 10 option, so that is solved.

But the slow booting 3 to 5 minutes (maybe a tad longer as it isn't fully operational for say 5 minutes). 

I am going to go into my Start-Up and see if I can't eliminate some items. That may speed up things a bit. 

As far as where the BIOS is pointing I assume it's my SSD C (supposed to be faster booting) Drive. I am more used to the old BIOS, with the newer modern UEFI version a bit foreign to me. That I will be having cataract surgery soon, maybe this summer hasn't helped me see the BIOS options as they are in a light blue color. But if you can point to specific areas to look at, please let me know.

As far as I can tell, the SSD is the only drive listed for bootup, with another option. I will snap a picture of the order and upload it.

For now here is my Disk Management Dialog window.

I went back into the BIOS. First I disabled a few startup programs, and I also put my BIOS at AHCI from RAID. (I had toggled this back and forth before, though it seems it should be at AHCI)

Those two changes probably made it boot a bit faster, but still 3 minutes.

So a peculiar thing in the BIOS, so three images to show.

First, the boot order shows that it first: Windows Boot Manager, Second: UEF1 ST1000LM035...  That is my HDD disk. There is no option for my M.2PCleSSD-0/SATA-2 drive to add. 

You can see in 'Drive Information (2nd image) that BIOS recognizes I have this SSD drive.

Finally: in image 3 that File Explorer has three items I can add. But I can't decipher what they mean?

As I may have stated in the beginning of this thread, but in case it's not clear, when I imaged my C drive, I did not want my D: drive touched. 

I decided after the three hour backup of my 128 Gigabyte smaller SSD (C: drive) that I should also make an image of my D: drive (1 terabyte drive, and it took almost 24 hours to complete.) 

That was a good move as when I rebooted the computer with the new SSD, I was greeted with a long reboot and my files on my D: drive were limited at best with unallocated space on the D drive. 

I created a virtual 'Data' drive for my D: drive and restored the files and data. 

The programs now on my D drive again work, though a couple give me trouble such as Word. But I can reinstall or tweak them.

I think I see the problem looking at my BIOS (the three images here) but I don't know how to go about fixing? It seems there is more than one way to attempt.

I am hoping to not have to restore my image(s) again, but I do still have the backup images for C and D drive.

I seem to be unable to add multiple images, so the next two will be replies to this post. The slowness of my computer with the seemingly reversed C: & D: drives in BIOS is slowing me down terribly!

@btcomp​ My second image.

@btcomp​ My third image

Your OS is installed on a Seagate spinning hard drive, whatever happened.  You will either need to reload the image to the new NVMe SSD (preferably with the hard drive removed from the system to avoid issues), or you'll need to install Windows to the new drive the same way -- i.e., disconnect the spinning drive from the system when you do.

This is my C and D drives

@ejn63​ Are there instructions on how to do. 

I would like to upgrade to Windows 11 sometime this summer. But I want this issue fixed first? 

The easiest method I would prefer? It's probably easy to disconnect the HDD D drive which it sounds like I need to do, maybe should have before I put the C image on the D drive.

I could redo that again, make a new image, but then I would probably need to do another of the D drive, which I don't want to do if I can help it. 

What would be the steps?

1. Disconnect the D drive (also disconnect battery before doing anything). I don't have installation software of course. I have no Disk Drive either. 

2. I have plenty of room on the new C: drive, so 700 gigabytes at least.

Thank you.

@ejn63​ Sounds good. It might be wise for me to make a new C: image. I put some desktop, documents, etc. on the new C: drive and may want to delete the dupes for sure, then reimage and do a fresh restore with the newer image first. It will take a bit more time, but I think worth it. Thanks.

@ejn63​ Hi,

I thought of something, and before I create a new image of my C: drive, that if my D: drive is the one loading Windows 10, perhaps the new image I create of my C: drive won't have Windows 10 on it. Then after I restore, I will have my data and programs back, will I have Windows 10 on the C: drive?

Maybe then I should just use my old image I made a week ago.

I have just a few new files on my C: drive, which I can move to my D: drive before I start. 

D: isn't the boot drive -- C: is.

On  second thought, I think I will try for the restore from the original image A week ago. I need to move some files back to D from C first.

I haven't yet done a new backup image on the C: drive. I did some research (YouTube) on creating a Windows Media Recovery. So picked up Dollar General's best PNY 64 Gigabyte USB to make a Bootable Drive. I also have one for iDrive's Reboot image. 

I'm not sure of the image created on my C: drive will have the system files I need to install Windows. So will do any backup C: drive image on Sunday. And of course disconnect D: drive, screws stay out of my case till the job is all done.

Oh, I have been wanting to get my Folders, (desktop, pictures, videos, music, documents...) moved to my D: drive but OneCloud has been interfering. Not an extremely biggie as that could all be done anytime. 

But what is aggravating is not being able to move some, the ones in an OneDrive directory. So I may just move them out and then put them on the D: drive if I can. They are scattered but trying to get them consolidated & remove any duplicates first.

I have been watching a video on OneDrive and though I do use it to write memoirs with and put on their Cloud, I find OneDrive to be a bit annoying.

Anyway I will try to update my progress tomorrow, but lots going on at home I have to attend to also. So Good Night from Eastern Time Zone. 

Continuing saga. It's Sunday morning, New York time and I discovered that my new 1 terabyte SSD drive doesn't have the Windows files on it. I removed my D: HDD drive and got this. I did create a Windows Recovery USB. I presently don't have a image of my new SSD so that I'm going to do. I have put the HDD disk back in, as I could not boot into Windows without it, hence it has the operating system, which is most of why booting is slow. 

So if I can just put the image of my new SSD onto to my 4 Terabyte Hard Drive to have, then I believe I will try to restore Windows, and see if it keeps my files. If not I have a free trial of Macrium Reflect. (I will look for a free version to have, Macrium is cool, but expensive)

I may disconnect my D: drive but first will try it in.
