I have three SSD, two with linux (a 240Gb and a 480Gb), and one with Windows (a 480Gb).

I opened my desktop to clean it, and afterwards I mounted the SSds in different positions (probably).

Now, when I choose my windows installation from the Grub, it show the message

error: no such device: 1832-7ADF
error: disk 'hd4,gpt2' not found.

I can find the Windows dick using nautilus, the files are still there. But neither sudo os-prober nor sudo update grub show my SSD Windows 10

Thanks for any help in advance.

I have a mbox file, with 200 emails, each with 4 attachments.

I want to extract those emails to a folder for each email, the name of the folder would be the title of the email, inside the folder a html file with the message, and all the attachments.

Is there a way to do that, using python, or a program?

I want to create a shortcut to pack the view of the current program on an area of my window.

It's like super+left shortcut, that shows as "split view on left" on keyborad->shortcut1 configuration, but I want to set super+numpad_8 to "split view on top", super+numpad_9 to "split view on top right corner", and so on.

How can I manage to define such shortcut? Which command can I define on "Command" in the "Add Custom Shortcut" window1?

PS: I'm using Ubuntu 18.04.3

The thing is that sometimes I type cd by mistake and that take me to the home directory.

e.g. I'm in a directory that have a hidden directory and a visible directory, I quickly press cd+tab and that takes me to the home directory
