Win7UpgradeWin10Rear Hard Disk(Partition)Access denied and cannot be accessed

I finally received Microsoft Update win10 package push information yesterday, so I can't wait to update it! The process was quite smooth. After the system was upgraded, I thought I would mess up another hard drive system, but I didn't expect Microsoft to give me a very tall dual-system boot menu, and both systems can run normally (you can see my other memo about the upgrade ).

The problem I encountered was as follows:

First, describe the basic situation of my computer: I have two hard disks, one is the win7 system, the other is the win7 system, and now upgraded to the win10 system. Before the upgrade, both systems can view and access each other's hard disk.

After a hard disk is upgraded to a win10 system, it cannot access the hard disk in another win7 system. The error is shown.

Why is it inaccessible? The hard disk information can be displayed clearly. Open the attribute to see:

Right-click the hard disk and choose properties:

The problem arises. It turns out that there is no access permission! In this case, I will reset the access permission.

Click "advanced" and you will see that there is no user permission in it. You need to manually add it. Click "change" Owner:

 

Click Change and then click Cancel. Two users are displayed:

 

However, this is not enough. You also need to add one:

 

Click Advanced

Click search, select the users user, and click OK.

 

Then click OK.

 

Then we can see that the owner has changed to users, but the following permission entries do not have the permissions of this user. You need to add them again. Note that you do not need to close them. Click Add in the lower left corner.

 

In the displayed permission settings box, click Select subject in the upper-left corner, repeat the previous user selection operation, and select the users user.

Set permissions to folders, subfolders, and files, and select full control. Then, OK.

When we return to the upper-Layer Program, we will see three users:

 

Finally, click "application" and "OK", and you will be able to access the hard disk after several minutes!

 

If the hard disk is large, it may take a little longer.
