UPDATE 11/23/2020: Am reclaiming Media Library space by deleting old pics. Trying to thin out the Media Library’s pics from posts that get few visits … hopefully it doesn’t ruin your view of the post.

I like to do clean installs, or I should say I don’t mind doing them; however, many people don’t want to do any installs at all, and that also includes a lot of Linux users. Ubuntu just came out with the 18.04.3, and I have done so many tests w/ the Ubuntu 18.04.2 versions on computer ‘Rose’ and laptop ‘Ace’ that I decided to just install the new Ubuntu 18.04.3 on both. This 18.04 version will have 10 years of long-term support (LTS), and the 18.04.3 is “third of five point releases” that have been planned. The ability to just upgrade to it is there, but installing the brand new version is simple and fast enough…if you have reasonably prepared for such, especially on laptops (since they lack the size and flexibility of a desktop). I had prepared my 240GB SSD that WIN10 and Ubuntu 18.04.2 were going to share when I did this post: Ubuntu and Windows 10 share a Laptop. Tests were also needed to prepare that SSD, since I wanted to be able to keep Windows Boot Manager as separate as possible, and to be able to switch to it in BIOS if I wanted to just use WIN10 mainly. However, Ubuntu’s boot loader will see another OS, and usually includes it in the Grub boot loader – no matter what, and that would be OK since I planned on using Ubuntu as the main OS on laptop, but also wanted the option to boot WIN10 without having to go into BIOS to change settings. Main Point being – I wanted that SSD set up where I could delete Ubuntu and install a fresh version if I wanted … all done *WITHOUT* disrupting the WIN10 installation. It all worked out the way I had wanted – hooray! Installing “Ubuntu alongside Windows Boot Manager” may work, but I’m not prepared to gamble on that method (with my brand new laptop!), and had problems doing it that way years ago – maybe it’s changed since then, and I might test it that way again in the future; however, I know this way works perfectly for what I require. I’ll have some pics later in the post.

I bought two of these 240GB SSD’s from Newegg awhile back, for $25.99 each – w/ free shipping and no tax…one is my main laptop SSD, the other is a spare that I can use for testing. I installed Ubuntu 18.04.3 on that main SSD yesterday, and then decided today to go thru the full process (using the spare SSD) so I could do a post on all the steps, with pics, for any interested laptop users. Some ‘Fanatical Linux’ users buy a new laptop, and then delete any Windows OS from it, just so they can install Linux on it – I’m serious! They don’t care what the OEM or store charged them for that Windows OS license on that laptop – they just literally *HATE* Windows so much that they don’t care about throwing away their money. Don’t ever believe anything those idiots say – their hate blinds them from all truth and facts.

OK…you just bought a new laptop – it has a Windows OS on it, but you want to install Ubuntu on it with that Windows OS. First: Do a full backup and create a system repair disk. Now, let’s resize that Windows partition:

Click C: partition and select shrink or resize:

Used Computer Management to do that, and shrunk it by 48127 MB which left us with about 180 GB on the Windows partition. Converted the remaining free space into a new 47 GB partition for Ubuntu (F: above)…formatted to ntfs which we’ll convert again later in the Ubuntu installation. Another step I had done earlier was to save my W10 Taskbar icons/apps, and also Ubuntu’s panel icons/apps…makes it easier to set up apps again later:

Now we’re almost ready to install Ubuntu 18.04.3 to the new partition. First, when I installed it yesterday on the main SSD, all that I had to do was to delete a partition that Computer Management saw as – (F:) 47.00 GB RAW a Healthy (Primary Partition) – then created a new partition in that same free space, and then formatted to ntfs (basically same as above). Installed Ubuntu 18.04.3 in that old space left by deleting Ubuntu 18.04.2. Never disturbed WIN10…here is a pic of operation:

Here we go with the new Ubuntu 18.04.3 installation. Insert the ‘Live’ Ubuntu media, and selected F12 for the Boot Menu…selected the USB drive. I have gone thru installing Ubuntu other Distros on this blog, and I’m going to skip the usual installation progression (e.g. location, language, keyboard, etc.), i.e. mainly just Installation type and partition stuff:

I had mentioned earlier about using the “Something else” selection instead of installing “Ubuntu alongside Windows Boot Manager.” Next up in the Installation type is the 240 GB SSd – in this case, /dev/sda and its different partitions:

The /dev/sda4 is where Windows is installed. We select/highlight /dev/sda5, that is where we’re installing Ubuntu, *AND* we’re also going to select /dev/sda5 as the Device for that boot loader dropdown area, after that we select the “Change” button next to the + and buttons, and a popup come up:

Go to the “Use as” dropdown and select “EXT4 journaling file system” then check “Format the partition,” and then go to “Mount point” dropdown and select “/” (AKA root partition). Double-check everything and then click OK.

Final step before installing … Triple-Check everything here, i.e /dev/sda5 should now have ext4 next to it, followed by the / then make sure a check is in the box – all that row should be highlighted (orange probably), then make sure /dev/sda5 is entered as Device for boot loader installation … last chance … if you’re sure, then hit the “Install Now” button at lower right:

OK…I lied about that being the “Final step before installing” – are you sure you are ready? Hit “Continue” and installation will continue, asking the usual “Where you are?” and “Who you are?” stuff…then it’s almost time to restart.

Here’s Ubuntu 18.04.3 on ‘Ace’ the Laptop:

Here’s Gparted’s view of the SSD with WIN10 and Ubuntu on it:

I don’t have a real camera, and don’t know how to get a screenshot while off of the actual desktop/laptop, but I do have some pics of Ubuntu Grub boot loader, and some BIOS shots using an old tablet’s camera:

Jpeg

Terrible, huh – zooming in is just moving closer:

Jpeg

That’s the Grub header…must be getting closer:

Jpeg

There it is! Grub boot loader menu with Ubuntu first, the options for Ubuntu, and finally Windows Boot Manager. That boot loader boots to Ubuntu pretty quick, so move fairly quickly if you want to boot Windows. Next up is a couple really terrible BIOS shots:

Jpeg

Acer BIOS sees Ubuntu as “Windows Boot Manager” – the #2 selection. The above shot is with Windows as the first boot option, i.e. the top one with the long number next to it. Here’s a shot after I made Ubuntu the first option:

Jpeg

OK…that should be it. BIOS is now set for Ubuntu 18.04.3’s boot loader to show up quickly, and it boots into Ubuntu in a few seconds if you don’t select Windows Boot Manager. BTW, Ubuntu don’t care that Acer BIOS has no clue who ‘He’ is … Ubuntu knows, and ‘He’ also knows who and what Windows Boot Manager is and does, waaaayyyyyyyyy down there at the 3rd choice level!
