I have an HP Elitebook 840 g4 8GB RAM and 512GB SSD. I have dual boot (Windows 7 and Ubuntu 21.04), but I want to install Ubuntu 20.04 LTS instead (and remove older two OS’s).

UEFI or BIOS based hardware? If UEFI better to install in UEFI boot mode. Most Windows 7 installs were BIOS and then drive would be MBR(msdos). But UEFI highly recommends and Windows only installs in UEFI mode to gpt drives. Conversion from MBR to gpt will totally erase drive. UEFI/gpt partitioning in Advance, new versions use swap file so swap partition optional: http://askubuntu.com/questions/743095/how-to-prepare-a-disk-on-an-efi-based-pc-for-ubuntu

It’s really pretty straightforward.

The official guidance tells you how to do it:

https://ubuntu.com/tutorials/install-ubuntu-desktop#1-overview

You’ll need to download Ubuntu and create a bootable usb -

https://ubuntu.com/tutorials/create-a-usb-stick-on-windows#1-overview

I’ve always found that easiest to do using Rufus in Windows.

Then back everything up - you’ll lose any data on your drive in both Ubuntu 21.04 and Windows 7.

Power off the machine, then when you power it on with your newly created Ubuntu USB in (you may need to change the boot order to usb first), you can select to install Ubuntu and you’re given the option to install alongside the current OS’s or instead of the current OS (‘Erase disk and install Ubuntu’). You obviously want the erase disk option as you don’t want to keep any of your current OS’s.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
