Win10 old computer hard disk to the new computer, boot to password?

Yes should be because the system is on the hard disk.

6. After the settings are saved, [Shut down and restart the computer] check the password field, and enter the password once.

Nursery even; It is forbidden to do things that should not be done:

In the settings of the Start menu, select Microsoft Account Login, then switch back to Local Account, which will allow you to reset your username and password.

In the win10 system, click [Start] -- Computer Settings] to enter the computer settings interface, and click [Users and Accounts].

Click on the login option, where you can set a password, **password, etc. What I'm talking about here is setting and updating passwords. It's the change button right below the password. If it is blank, you can set it.

Enter your current user's login password. Click Next

Enter the new password two more times. In this way, the previous login password has been changed. Use a new password the next time you log in.

Click [Finish] to set your computer boot password successfully.

According to my guess, it may be that after logging in with a Microsoft account, he has been saving the password information in the computer, and if he does not log out and changes to local login, he will always be local.

Guess** - If the computer is not connected to the Internet, but we can still log in to our computer with the Microsoft account password.

Let's change the password, I just changed the password and logged out of the local login, and then changed to log in with a Microsoft account, and the password is the new password.

Are you pretending to be some kind of restoration elf or something, if so, that's it.

Either you have failed to change your password. Or change the password of another account.

When your original hard disk is still an MBR partition, it will start from it no matter what, no matter how you set it up, it is useless, if you want to use it normally, delete the main partition of the old hard disk and deactivate it.

Turn off the power, open the case cover, buckle the motherboard battery for ten minutes and then reinstall it, if it still doesn't work, reinstall the system.

OK. Generally speaking, just add an extra SSD. It's not as complicated as you say, remove the old one, install the new one, install the old one.

Generally, the SSD you set now starts first, and the motherboard reads the system on the SSD, and only by modifying the SSD boot file to dual system boot can you directly boot the second system.

Bootice is recommended for modifying software

The old win7 will work. Just make a different system choice. When booting up, you need to enter the BIOS to select the boot and boot the hard disk. This is called having two systems. Not a dual system.

The dual system has a boot menu that allows you to choose to use win10 or win7 when you boot upAnd both systems are installed on the same hard disk.

Personally. I like that the two systems are installed on different hard drives. A is bad and B is repaired. B bad use a repair. It's a little safer that way.

And the dual system is easy to go wrong, and even the two systems cannot be used. The dual system is easy to use. But if something goes wrong, it's troublesome.

Or your password hasn't been changed, so you log in first. Then reset your password again.

U disk boot reinstallation system installed in C disk software or data of other disks still exist.
