I've downloaded a CentOS-7-x86_64-Minimal-1511 iso file for testing purposes. I also have Hyper-V on Windows 10.

I loaded the image file and as far as configuring the below there was not much to do and went on to proceed:

enter image description here

I then click Begin Installation. Afterwards, it requires me to reboot which I did.

After rebooting, I see the below and I just went with the first selection and hit enter:

enter image description here

After the above, I see the below and don't know what it means and proceeded to wait:

enter image description here

Finally, I see the below:

enter image description here

With the above image is where it all falls apart. I know for a fact that I did not set a username yet. However, I did set a root password and that was all. Every attempt I make I get the error message "Login incorrect".

Am I doing something wrong? What is required for the login when a username has not been set?

I'm new to Linux and require some assistance. Any help would be appreciated.

  • Did you create a password during installation?

I guess you forgot to set password while installation, now you can workaround by resetting root password.

Follow the below procedure:

1 – In the boot grub menu select option to edit.

2 – Select Option 1 to edit (e).

3 – Go to the line of Linux 16 and change ro with rw init=/sysroot/bin/sh.

4 – Now press Control+x to start on single user mode.

5 – Now access the system with this command. >> chroot /sysroot

6 – Reset the password. with >> passwd root

7 – Update selinux information with >> touch /.autorelabel

8 – Exit chroot >> exit

9 – Reboot your system >> reboot

its Done now you ll be able to access with your newly set passwd...
