I am using Ubuntu latest version (currently I believe 22.10 with latest build, I update periodically)
Recently,I got too absent minded while I was fixing some error, and after spent couple of hours trying t resolve this issue, I was not thinking at all I guess, went ahead and deleted this X11 folder inside the system /bin folder, and to make things worse, I rebooted the system. that was the last time I saw my computer intact.
since I have 1Gb or storage, I installed another Ubuntu alingside the "corrupted" Ubuntu that I've been using for years.
I was wondering if there is a way to copy some of the needed folders/files from this new one, put into the old one, and resurrect that system again.
PS: the /dev/sha3 is the corrupted system, and I installed /dev/sda4 as temp system to see if I can still save the old system.


all of my problems started when I deleted that X11 folder (without knowing X11 was symlinked to /bin )
can someone kindly, show me the way to restore the old system, and after restored and tested that it's okay, how to safely remove this new temp system, and re-allocate the storage back to the old system.
I tried to be as clear and provide as much details as possible, please feel free to ask below, I will update this post or answer to your question to by best ability.
Thank you very much!
