OS Ubuntu 20.04 VirtualBox 6.1.32_Ubuntur149290 Running Windows 10

I got this following error and I have work inside my VirtualBox that I really do not want to lose.

I have found a similar problem here. But I am not sure if this will delete my current work the virtualBox and I do have enough rep to ask further questions on the original post. Please help.

I also run this and it seems like I have the correct architect for my OS

spock@spock-uss:~$ dpkg -l virtualbox* | grep ^i

I am trying to solve this problem here following steps here and someone suggested the following to me

The installer may have expected you to make a partition on the free space, before you went into the install step. Most installers force you thru this step. You have to 1. make a partition, 2. put a filesystem on it, usually ext3 or ext4, and 3. give it a mount point name (eg /). You usually need to make a minimum of a root filesystem partition ( called /), and a swap partition. So when you did step 4, you only made free space, not a partition.

unallocated memory see here

Would someone shows me how to make this unallocated memory partition of the filesystem?

OS windows 11 on hp w/ 1 TB memory. This is a new laptop that I just bought and have nothing on yet.

I am trying to dual boot windows with ubuntu 20.04

following these steps here except that I used Rufus to create a bootable USB drive because for some reason Balena was not working for me.

The problem as you can see pic that I do not see the unallocated free space? And I also do not see the install ubuntu alongside Windows boot! So from the second image what should I select?

/dev/nvmeOn1

or 

/dev/nvme1n1

OS ubuntu 20.04

So for my school work, I am connecting to a Linux server using my school username and password.

example in terminal:

ssh me@name-of-remote_host

me@name-of-remote_host 's password: ....

' [me@remote_host~]: sqlplus

this will prompt me to enter:

Enter user-name:

Enter password:

If I want to change the second (sqlplus) password how I would do that assuming that I have the privilege to do so?

Also, can someone explain to me or reference some resources to understand how all this been created from the school end point? Is it just creating Linux server with users and for sqlplus same thing?

I was trying to move files from one dir to another and I missed up my home director can someone help me undo this script. everything in my home dir now put in dir called myfiles. I am on Ubuntu 20.04

mv ~/my_files/master_cs/jv/foundation_cls/ -v !("~/my_files/master_cs/jv/foundation_cls/cop_5007") ~/my_files/master_cs/jv/foundation_cls/code_snipt

I am using Windows 10 and Ubuntu 20.04 both connected on the same Wi-Fi.

I need to be able to share files from win to Ubuntu and vice versa.

I am trying to follow the steps here which seems every straighforward but when I try to add network location, a window security pops up and asks for credentials (username and password). I have tried to enter my Ubuntu login username and password but it did not work.

What are these credentials that I am asked to enter? Is it something I need to figure out from my Ubuntu machine or on my win?
