Linux On Laptops

HP Notebook 15-bs525ng

I describe the installation process of the basic system only. I didn’t make any testing of the components except the correct user-login.

Installing of debian-10.7 to this machine was trouble-free.
The installation requested to additional firmware: rtl_nic\rtl8168h-2.fw
Searching with bing: firmware rtl8168h-2.fw
showed the site:
and further:
Downloading brought the package: firmware-realtek_20201022-1_all.deb
This file I copied to the Root-Directory of an other USB-Stick and the installer recognized it automatically.

The Procedure of Installation:

I opened the image of: debian-10.7.0-amd64-DVD-1.iso
and copied the whole content to an USB-stick, which was formatted with FAT32.
The stick is automatically UEFI bootable then.
Plug in the stick and reboot the notebook.
While booting press the ESC-key and the boot-menu appears. (At the start of the boot process you can see, when the screen gets power - it becomes a little brighter. That is the point in time when it recognizes the periphery and reacts to the keyboard. Now press the ESC-key! The boot-menue appeares.
Press F9 to show the bootable devices, F10 to enter the Setup-Utility.
To start the installation select the USB-stick from the bootable devices.


I wanted Windows-10 keept alive.
Windows took up all the space on the 1TB HDD, but was only 100GB in size. The partition could be reduced to 600GB with the Win10 Partition Manager.
Linux took the now free 300GB and installed it without any problems.
Debian installs the Grub boot manager, but can only be reached via the boot menu with F9. However, this is yet to be changed.
To change it, you go to the SETUP (F10) when the computer is booting. Now select System Configuration > Boot Options > OS boot Manager.
There are two entries now:
  - Windows ...
  - debian ...
By pressing the F5 and F6 key this sequence can be changed and Windows should be set behind debian. Now the GRUB bootmanager is booting.

The Debian installation program also offers the option of shrinking the Windows partition in order to free up space for another operating system. I didn't test it.

Using an other partition-manager (PartedMagic) i shrinked the Windows partition to 300GB. Windows was starting, but reported some problems. After series of CHKDSK and Auto-Repair (> 5h) Windows-10 recovered itself and is stable now. For Debian I did a reinstallation with 600GB now.

Not recommended:

Doing the setup of debian using Windows by executing setup.exe of the USB stick did not work. Setup wrote an entry to the Windows-bootmanager that din't work and it was rather tricky to remove. Instructions to get it done I found by searching with bing <bootmgr windows 10 edit> and got
