Latest update seemed to remove windows10 from the grub

The dualboot was removed during latest system upgrade (that had kernel header upgrades, etc).

UPDATE to status:
Dualboot is now back after latest kernel update...

Hi, I can"t comment as I have left Windows 10 behind. However, if I was dual booting with 10 I would have applied Matthew Moore's method of dual booting.

Great...
Do you know how to install times-medium fonts to ZorinOS?
I can not find this.

You need to install Wine 4.0 first using Synaptic Package Manager plus any other dependencies - usually when it installs it will ask permission for you to install Wine Mono plus 2 x Wine Gecko packages. MS Fonts are available from Sourceforge.net:

https://sourceforge.net/projects/corefonts/files/

Alternatively, if you have them within Windows 10 and can access your Windows 10 Fonts folder, copy them across to your Zorin desktop. Then in a Terminal Window (Ctrl+ Alt+ T) navigate to the Fonts folder on Zorin:

Code:

cd ..
cd .. [should get you to root home folder]
cd .. [should get you to root of file system
cd usr
cd share
cd fonts [then ...]
sudo chown [yourusername] fonts [You will need to enter your login password to elevate you to 'root']

Then using Nautilus (file explorer) navigate to usr | share | fonts and drag the required font/s into the Font folder. If it is true type font you will need to drill down to the truetype folder within fonts and use the sudo chown command for that folder.

It seems to work to use the Windows10 fonts... In fedora these fonts were available through the dnf rpm.
But I have to check again how to get the grub dual boot settings back - or should I try make 4 OS boot by the grub..
Looks complicated. Using multiple OS gives more choices with the application software and setup options.

Wonder if a BIOS update might resolve the issue?:

https://www.linux.org/threads/ubuntu-18 ... ure.23126/

I don't know BIOS. But this has the latest bios version available from the hp-site.
It could be faulty BIOS though, because I can not upgrade memory more than 4Gb.

Something must be wrong as digging around it should be upgradeable to 16 Gb if Intel CPU or 8 Gb if AMD CPU:

Yes. Something must be wrong.
But upgrading above the 4Gb hangs the system during memory testing and sometimes when using the computer.
I hope I knew it better what is wrong and if that can be fixed or not...
It's certainly then related to the memory, but how? BIOS? Heating? CPU? memory-interface? slot-failure? PCB-pattern failure?
I don't know where to get complete diagnostics, that can check why memory is failing.

Have you run the diagnostic test that comes with the Notebook? I know Dell has one built in. I would advise you use this:

https://github.com/phoronix-test-suite/ ... test-suite

Not sure if I can repeat the issue, because no more 8Gb configuration, because that crashed. Then only 4Gb installed and available for testing..

The "test suite" can not find the "RADEON GRAPHICS"... Is there missing drivers in this machine or is the
RADEON disabled for some reason(s)?



Some memory tests, even with 4Gb of memory seem to quit the test rather than finishing it:

I tried to install the graphics drivers as in the below post:
https://askubuntu.com/questions/1066105 ... untu-18-04
But it seems that it disabled my keyboard and mouse and I had to reinstall the Zorin15OS.
I'll try again, but hard to see why this happens... It locked the mouse & keyboard again.

I will check if below is hot to do it, and what will happen:
https://www.amd.com/en/support/kb/faq/gpu-635

I'm suspecting a soldering failure on the motherboard PCB prevents upgrades above 4Gb. Or maybe there is some secret
"jumper block" that should be removed for upgrades above 8Gb..?

The "Phoronix-test-suite" gives messages as:
[NOTICE] A non-numeric value encountered in cpu_usage:53
[NOTICE] A non-numeric value encountered in cpu_usage:53
During running the tests...
What would this mean? Maybe a "bug" in the test-suite itself?

It could be a bug or the hardware is no longer up to it - I don't know how old your rig is but when my 10+ year old rig repeatedly warned me that my case had been opened (which it has for years for quick disconnect of drives), no more BIOS updates and still boot errors I decided it was time to build an up-to-date rig with a decent amount of RAM and a decent RAM manufacturer at that.

IT seems have a lot of test and also, does it bring virus into my system?

I'm somewhat bemused - just downloaded the latest .deb package, scanned with clamtk and no threats found - suspect it is a windows av false positive?

The phoronix-test-suite (at least some tests) carries some viruses or malware.
