Dual Boot W10 and Linux

[ValerioP]

I'm actually writing from my laptop in Debian/Linux, so I can say I'm partially successful.

There are several problems that I have "solved" and I'm leaving here some casual hints just to help others.

1) GRUB installation. I think you cannot install grub as a main bootloader unless you trick the firmware in some way (never tried yet), hence the installation "fails". Don't despair! Just go on and reboot  then you press ESC at the boot process and enter the UEFI firmware, it's possible to boot from file and you can choose GRUB (it's in a separated folder that you can easily recognize).

2) Many ACPI errors that hinder the booting process. You can totally silence them using nomodeset apci=off in the kernel parameters passed by GRUB at boot, but you are left without graphic card support. After a more focused search, I've put this lines as kernel parameters (remove acpi=off):

nomodeset acpi_osi=! acpi_osi='Windows 2019' pci=nommconf

3) I've used the Debian/testing+firmware DVD iso release to install everything needed to make wifi card, ethernet card and Nvidia card work. I thought that a modern hardware requires the most updated kernel, especially the graphic card. This is something you cannot find easily in Debian stable releases!

4) Using the smartphone as a connectivity provider. If you have any problems with the WiFi/Ethernet card configuration, your smartphone sharing connection function through USB tethering is a good solution because then you can install everything you need from internet.

5) I've "chrooted" my Debian installation many times from my USB stick to update it to a level it was bootable. Being prepared to "chroot" you system is key to solve many problems.

6) not everything is working: the touchpad seems dead at the moment, so use a USB mouse.

I don't know if I will be able to fix everything and write a guide about this, but until then I think that someone in need can try my suggestions.
