(Version française / French version)
Here are different installation methods validated by the LibraZiK team. These installation methods can be done for 64-bit systems or for 32-bit systems.
Method 1 - Complete installation from a Debian (Buster) base:
→ With a USB key (or a CD, DVD,...) for online installation
Method 2 - Update from a LibraZiK-2
→ Update from a LibraZiK-2 (in French) (not recommended)
Method 3 - Installing LibraZiK-3 using a “live” :
→ With a LibraZiK-3 live
On a BIOS machine that contains several systems, if you'd have a problem with not detecting one (or more) system(s), you can try to correct the boot GRUB menu options with the following commands in a terminal:
update-grub(as a super-user account): GRUB rescans the various operating systems available on the machine, and then updates its configuration,
grub-install /dev/sda1) (as a super-user account): writes its configuration on the device /dev/sda.
After these two commands, reboot your machine and the LibraZiK-3 boot menu should appear and give you the right boot options.
If you wouldn't have the LibraZiK-3 start menu, you can try the following in addition to the previous commands:
And now you should have the LibraZiK-3 start menu.
This should work in the majority of problems cases with the LibraZiK-3 GRUB boot menu. If it doesn't, you're probably in trouble. Sorry. You can help yourself with the RescaTux and Super Grub2 Disk tools.
On some newer computers, BIOS technology has been replaced by a new UEFI technology to configure the boot options of the operating systems. LibraZiK-3 can works with UEFI.
Note: on a machine equipped with this UEFI technology, if you want to achieve multi-booting between LibraZiK-3 and Windows 10 for example, you may need to disable the “SecureBoot” technology in the UEFI configuration.
It has been reported that for some ISO images, problems with autostart on the USB stick could sometimes be solved by changing the BIOS settings in the “UEFI/Legacy” family choices.
Note that there is a documentation effort to install Debian on specific machine models whose documentation can be found here.
