Hard drive not showing in windows 10

I have a old machine that I want to remove files from. I took the drive and made the active partion NOT ACTIVE as it was a windows 10 drive. I took that drive in inserted into another machine with a clean install of windows 10. I want to copy the files off of this drive after I put it into this clean install of windows 10.

The bios sees the drive, windows 10 however refuses to see the drive. I have a bootable Windows 7 mini OS at it DOES see the drive. I took my mini 7 bootable OS flash and put it in the machine with the new clean insatll of win10 and the old drive as well and I will copy the files with MINI 7 perhaps I will find a way to copy files and retain the dates of the files.

ANYWAY I am confused as to why windows 10 wont see it. I am confused as what I can do to make windows 10 see this drive.

If I use diskmgmt.??? to add the drive I am betting that it will want me to reformat it and that undermines what I wish to do.

I am a bit confused as to why mini 7 will see the drive and its files, the bios knows it is there yet windows 10 cant or wont recognize it. ?

As long it is partitioned and formatted in a standard way that Windows will recognize the Windows 10 computer should have no problem with it.

I can take a drive out of any of my computers and Windows 10 will see them fine. For example, I can take the drive out of one of my Windows XP computers and Windows 10 will see the contents fine. Of course if I do something like this I usually put the drive in an external enclosure instead of mounting it inside the computer.

Post a screenshot of Disk Management showing the drive.

To see the drive on explorer the partition must have a drive letter assigned to it.
Drive letters are assigned by the OS so under mini 7 it can have a drive letter assigned and under Win 10 it may not.

If you have a MiniTool or AOMEI Partition use it instead or Windows disk manager.

So now it is showing up, I have this installed on a windows 10 machine that is isolated from my network. I am trying to copy the pictures and files off of this drive. The users folder wont let me access it because it was a users folder that had a password protection on it.
This machine had a virus and Norton could not remove it, So my solution was to take the drive out and copy the pictures and files on a isolated machine. I did not reaslize that i could not access the files because of login protection. I am wondering maybe if I put the drive back in the PC that it originally was in and remove the password protection on the user then maybe I could copy the files that way.
It looks as though I am going to start over. I think I will boot up that old machien with a virus and install a second drive in that machien and then use tera copy to get the pictures on to a second drive then put that drive in my isolated machine that has the latest norton on it and scan that said drive and hope the virus is not on this drive.
Norton found ISB.downloader!gen177 on the machine that I am trying to get the files off of. Norton said it could not remove that so my solution was to copy the files through the back door and hopefully what ever that virus was it would not catch on to the fact that I was trying to back things up.
Currently I am working with a clone image of the hard drive that has the virus meaning I cloned this computers drive to a solid state drive so I am working with a cloned copy of the drive from the computer that was infected with ISB.downloader!gen177. I do not want to plug that machine into my network and I will not plug the copy of that computers drive (a ssd IT drive) in any computer that is plugged into my network. I have a PC that i put win 10 on and put norton on and I updated the virus definitions so I can scan data in a isolated way. Its become a trick to get the files off of this PC since it has a virus.
Currently now, if I could remove the permissions from the users folder here I could then copy the files. SO maybe I could put the drive back in the PC and remove the login password for the user and maybe then I could access the data. OR there are other routs to go here. This old PC with the virus has windows 10 on a dual core processor and a old style hard drive. SO it would be a slow process to get the files off of it especially since the OS is in poor running and problematic condition. THis is why I hope to be able to get permissions removed from this users folder so I cna access the drive. So I guess I will try to remove the password from the user so I can then possibly have acess but I do not fully know at this point if that is possible. Can a users folder be accessible if that users folder no longer is password protected ?? I found this:
https://learn.microsoft.com/en-us/an...ld-user-folder
I do have the username and password for this machine. So that will help. I am jsut not sure the best method.
I will need to go back in and find the right partition and mark it active or reclone the old hdd to it to go back in and remove the users password on the account. So this is getting a bit more messy than I expected. The old PC only has USB2 so that makes for concerns as well it would take forever to copy the data to an external drive.

I was able to copy the files with win 7 mini but when they were all gone - I think windows 10 must have realized what I did and for security reasons it just deleted the files because it knew permissions were not right. Mini windows 7 will see the files. I used a teracopy to copy the files and it must of retained the file permissions and tha tis why they are all gone now. that is the only thing that makes any sense. THis situation is getting complicated. it look like I may need to take my chances and use tera copy to copy the files on the OLD PC. I will at least try that with the SSD copy rather than the old clunky drive.
? It would be so much easer if I could simply access the files in that users folder. See I took the drive and marked the bootable partion inactive so I could put that in this newer isolated PC.

You can 'take ownership' of the folders (see the Tutorials section). That's a standard issue in moving drives from 1 PC to another- nothing new there. Convenient way to do that:
Add Take Ownership to Context Menu in Windows 10

But do you REALLY want to take the risk of connecting a drive which is infected to your PC??

It also sounds as if you don't have a backup of the files which you need to rescue... what.. no disk images? No backups? Really?

So your idea of using the old PC to copy personal files off to another disk seems better.

If the current user is different from the user that created the files you cant access them. You have to take ownership of them.

As you had a virus on the drive:
- On explorer options, unselect the Hide known extensions.
- Don't execute any file, just copy the files to your computer and then run a antivirus on them.

I certainly like how macrium file and folder mover worked out in this situation. 48 gig of pictures copied over with metadata in just a few minutes and it retains the picture meta data and gives me the option to remove permissions.

I do not see any way for a virus to jump into a router, and then to another machine. I plugged that computer that had the infected data on it into my router but only when all others were unplugged. A small chance that it could find my phone but I doubt it. I do not think a router has any place to be infected. I suppose the cmos on the router could get infected and I suppose a virus can infect a bios - I suppose the only real way to know is to overlay those (cmos/bios) with the same versions as before and use a hash to obtain them. I guess some types of viruses CAN overlay a router or Bios chip but it would be rare. I suppose to be as safe as possible I would need to find a way to prove my the writable chips on devices I use to separate data from virus not compromised.
