Continuing PCLinuxOS, this tutorial explains the configuration file for OpenMandriva Lx 4.0 --a beautiful RPM-KDE based operating system-- to boot in multiboot USB using GLIM tool. If you don't know GLIM, read first the tutorial. If you wonder, multibooting is important to save cost as you can run multiple distro installers by just one flash drive, without having multiple flash drives. To speak about config, OpenMandriva is very different to Ubuntu (even different to PCLinuxOS too) both in bootloader code and its internal ISO file structure. Thus, it will not boot from multiboot flash drive unless we write the correct code. I managed to ship a USB with it twice in Indonesia this month only. That's why I share my success with you here. Happy hacking!

Since long ago I could not make openSUSE multibootable pendrive except in single boot mode. I could not use MultiSystem nor Sundar's MultiBootUSB nor even GLIM.  What's more, I could not find any easy tutorial on the net talking about making it. Fortunately, and good news for us, recently I found Aguslr's Multiboot USB (MBUSB) that is able to create it. I have tested it and as I reported few days ago I finished the installation just as perfect as other distros I had with MultiSystem. Now it's my turn to explain how I did that in 4 steps: first, create a Multiboot USB pendrive; second, copy the ISO file to USB stick; third, boot your computer to USB; and fourth, install openSUSE with it. This USB setup can accept other distros to be bootable along with openSUSE. Enjoy!

Recently, I distribute GNU/Linux USB sticks with a bunch of video tutorials inside and I use Rsync command to copy the files with best reliability. I like Rsync because it is clear with progress and verbose messages, and in my cases it's often faster, more stable. I then use the same Rsync command to copy the ISO image files to USB as --you may know-- I am currently experimenting with GLIM and Aguslr's Multiboot USB tools. This works very well. Tutorial below shows you the command lines and examples.

After MultiSystem (2015), and then Multibootusb (2018), now I found GLIM tool (2019) by Matthias Saou to easily create multibootable USB to run and install GNU/Linux distros. GRUB2 Live USB Multiboot (GLIM) is a user friendly program to setup any USB stick to run multiple GNU/Linux LiveCD systems with fancy bootloader. GLIM supports both 32-bit and 64-bit computer either with BIOS Legacy or UEFI. With GLIM you can have multiple OS installers in one USB drive, take example Ubuntu and Fedora and Mint, to install them to computers so it saves a lot of your time. The difference between GLIM and the two tools mentioned above is, that using GLIM is easier, you simply need to copy ISO images you want to your USB stick without running application. Awesome, right? Then, how to use GLIM? This tutorial explains it with examples in easy way and with screenshots. Go ahead and happy doing business!

As many of you know, KDE neon is a special distro to bring the really latest KDE version from The KDE Project itself. KDE neon is a stable operating system as it's the official OS of Slimbook Laptop and actually I used it daily. But, KDE neon is available in User and Developer, Git-Stable and Git-Unstable editions. Previously, it even has a User LTS Edition. This may hinder us to download as we're not sure the version of packages inside it. How to know the differences between them before downloading? This short tutorial shows you the examples.

You may want to run 64bit ISO images of many GNU/Linux systems (i.e. GuixSD and Trisquel) using a virtual machine. You may have a 64bit laptop without virtualization support like mine. Then also you may have heard that virtualization systems like VirtualBox doesn't work if your laptop doesn't support virtualization (Intel VT or AMD-V). So, is there really no solution running ISO without virtualization support? The answer is there is a solution and that is QEMU, the full hardware emulator. Surprisingly, it's very easy to run any OS with QEMU command line once you know the examples. This article shows 2 examples in running GNU/Linux OSes with QEMU on an old laptop without KVM, without Intel VT support. Happy running!

Verifying checksum for a GNU/Linux image is similar to comparing fingerprints for human. It verifies that your downloaded Ubuntu image is valid or not. By valid here it means it's 100% the same as the file on official server. Whenever it's verified valid, then it's OK for you to use it and further to redistribute. But whenever it's not valid, it means the image is probably corrupted, broken, of even altered by somebody else. This short tutorial shows 3 steps to verify Ubuntu image for beginners.
