Installing Xubuntu Dual Boot with Windows (11) on Toshiba Dynabook R734/K Laptop

Installing Xubuntu Dual Boot with Windows (11) on Toshiba Dynabook R734/K Laptop

Comment

Xubuntu is an Ubuntu-based Linux distro featuring the robust, customizable, yet lighweight desktop environment XFCE. Now on this post I want to share my experience installing Xubuntu and dual booting it alongside Windows 11 on my Toshiba Dynabook R734/K laptop.

Nerdizen.xyz — Oh linux world is so vast, there are just too many choices of GNU Not Unix/Linux OS or Linux distro out there to explore. And now my journey on exploring Linux distros is arrived on another Ubuntu-based Linux distro, one of Ubuntu official flavor, it is Xubuntu.

I started interested to Xubuntu because how it is said to be lighweight, mainly because it is using XFCE desktop environment, probably. Anything sounds lighweight, is what I looking for because I will use it on my old laptop (while “old” here is an unclear term) Dynabook R734/K.

So, the power and advantage of Ubuntu backed by it’s community and user base while still being lighweight on system resource usage, yet very customizable thanks to the mature XFCE environment, are the main points made me want to try Xubuntu and dual boot it alongside the already installed Windows 11 on my Dynabook R734/K laptop.

Steps installing Xubuntu – dual boot with Windows (11) (example on Dynabook R734/K laptop)

Xubuntu desktop overview on my Dynabook R734/K laptop

Xubuntu version: 22.04.
installed OS: Windows 11.
media booting method: Ventoy.
device: Toshiba Dynabook R734/K

Steps:

  1. Download Xubuntu OS image from the official download page: xubuntu.org/download/
  2. Prepare the Xubuntu installation media. Here I am using Ventoy to make the Xubuntu iso image to become a bootable media.
  3. [Recommended] Prepare new empty partition on our laptop’s hard drive where the Xubuntu will be installed. For example we can use built-in tool on Windows “Disk Info” to easily split and make a new partiton on our hard drive. Usually the partition for a Linux distro should have a size around ±40 GB or more recommended. Give the new partition a proper label like “Xubuntu” or something like that so we can easily distinguish it.
  4. It’s a good idea to disconnect all external devices especially storage devices before hand to ease the installation process (avoiding formatting/erasing mistakes).
  5. Enter Dynabook R734/K “Boot Menu” (BIOS menu): Restart laptop, then when the power LED turned on (but the screen not turned on yet), repeatedly press the F12 key until it entered the boot menu/BIOS menu.
  6. Now we are in the BIOS Boot Menu. If we haven’t plugged in the Xubuntu installation media (e.g. USB storage stick), now is the time.
  7. The installation media drive should be detected in the Boot Menu list, we can just select it to directly boot into it (In my case here, to the Ventoy boot menu). Alternatively, we can adjust the boot menu to prioritize the installation media so it can boot it automatically if the installation media is detected when we restart the laptop by setting it:
    1. On the Boot Menu main menu, choose “Enter Setup”.
      Image for step 7.1
    2. On the side menu, choose “Advanced”, scroll down and choose → “Change Boot Order”.
      Image for step 7.2
    3. For example here I use a USB storage stick where Ventoy and the Xubuntu iso image is in, so make “USB Memory” at the top of the “Boot Priority Options”. Don’t forget to click “OK”.
      Image for step 7.3
    4. On the side menu, choose “Exit” → “Exit Saving Changes”.
      Image for step 7.4
  8. Now in Ventoy boot menu, first we might want to switch to “GRUB2 Mode” (increase compatibility in booting Linux images), press Ctrl+R to switch to GRUB2 Mode. Next, just choose the Xubuntu iso image to boot the Xubuntu OS live media.
  9. On the Xubuntu OS live media GRUB menu, choose “Try or Install Xubuntu” to boot into Xubuntu live image environment.
    Image for step no. 9
  10. Now we are on the desktop of Xubuntu live image environment. Click “Install Xubuntu” to begin the installation process of Xubuntu, or “Try Xubuntu” to try Xubuntu on the live image environment first and later we can bring back the installation window from the “Install Xubuntu…” shortcut on the desktop.
  11. Next proceed to Xubuntu installation wizard UI. Choose language → keyboard layout → connect to network (optional) → apps install preference (full or minimal), whether to allow install third party software option (recommended enabled).
    Image for step no. 11
  12. On the “Installation type”, because I have prepared the partition where Xubuntu I want to install to, choose “Something else” so I can pick the partition manually.
    Image for step no. 12
  13. Next the partition list window will appears. On the “Device for bootloader installation”, typically this should be the root of our PC main hard drive, that is /dev/sda.
  14. Then on the partition list table, right click the partition we want to use where Xubuntu will be installed, and click “Change”. On the “Use as” input, select “Ext4 journaling file system”. Tick the “Format the partition” checkbox. On the “Mount point” input, select /, then click “OK” button below it to confirm the partition settings.
    Image for step no. 14
  15. Next reselect the partition on the partition list table by left click it, then click “Install Now” button on the bottom menu to start installing Xubuntu to the partition.
    Image of step no. 15
  16. Proceed with configuring time zone, user profile, and wait until the installation done. After the installation done, we can restart our PC and the next time we restart it there will GRUB bootloader menu allow us to choose what OS to boot, the (X)Ubuntu or Windows (or other OS if you use it :D).

This tutorial may also be the same whether we have another Windows version installed like Windows 7, 8.1, etc., and/or with another Ubuntu-based Linux distros (and maybe most Debian-based Linux distros), though maybe there will be minor differences only in the OS installation wizard UI.

Comment

Who want to run Android apps/games on our large desktop or laptop screen? Me! Previously, I had installed BlissOS, one of “Android on PC” (Android-x86) OS on my Toshiba Dynabook R734/K laptop. Now I found a better Android PC OS in my opinion, it is PrimeOS.

But on this post, I will share not about just installing PrimeOS normally, but to install it alongside existed Windows 10 and Ubuntu MATE (Linux) on my Dynabook R734/K laptop.

Steps installing PrimeOS – multiboot with Windows and Linux (Example on Dynabook R734/K laptop)

PrimeOS version: 2.1.0 (iso type)
installed OS: Ubuntu MATE 20 & Windows 10
bootloader: GRUB
device: Toshiba Dynabook R734/K

Steps:

  1. Download the PrimeOS iso file from it’s official website: primeos.in/download/ and make an installation or bootable media of it, for example using Rufus (recommended) or Ventoy.
  2. Prepare a new empty partition on our laptop’s hard drive where the PrimeOS will be installed. For example we can use built-in tool on Windows “Disk Info” to easily split and make a new partiton on our hard drive, usually the partition for an Android-x86 OS should have a size around ±40 GB or more recommended. Give the new partition a proper label like “PrimeOS” or something like that so we can easily distinguish it.
  3. It’s a good idea to disconnect all external devices especially storage devices before hand to ease the installation process (avoiding formatting/erasing wrong storage/disk).
  4. Enter Dynabook R734/K “Boot Menu” (BIOS menu): Restart laptop, then when the power LED turned on (but the screen not turned on yet), repeatedly press the F12 key until it entered the boot menu/BIOS menu.
  5. The installation media drive should be detected in the Boot Menu list, we can just select it to directly boot into it. Alternatively, we can adjust the boot menu to prioritize the installation media so it can boot it automatically if the installation media is detected when we restart the laptop by setting it:
    1. On the Boot Menu main menu, choose “Enter Setup”.
      Image for step 4.1
    2. On the side menu, choose “Advanced”, scroll down and choose → “Change Boot Order”.
      Image for step 4.2
    3. For example here I use a USB storage stick where the PrimeOS has been burned using Rufus is in, so make “USB Memory” at the top of the “Boot Priority Options”. Don’t forget to click “OK”.
      Image for step 4.3
    4. On the side menu, choose “Exit” → “Exit Saving Changes”.
      Image for step 4.4
  6. Now we are on the PrimeOS installation media boot menu, select “Installation — Install PRIMEOS to hard disk” to begin installing PrimeOS.
    Instalation media boot menu PrimeOS Dynabook R734/K
  7. Next, the installation wizard of PrimeOS will appear. The first one is we choose the partition where PrimeOS will be installed in it. Then on the “Choose Filesystem” window, the best one will be ext4. But, Since my PC hard disk is still partitioned in MBR (BIOS boot mode), here I use ntfs instead.
    Installation wizard choose partition PrimeOS Dynabook R734/K
  8. On the GRUB bootloader installation choice, I choose “Skip” since my PC has already using GRUB bootloader and I will add the PrimeOS boot entry to the GRUB bootloader later manually.
  9. The installation wizard will begin creating the system directory of the PrimeOS, since I’m choosed ntfs as the partition format, it is actually creating system.img with size of 3507384 <abbr title="kilo Bytes">kB</abbr>, rounded around 3.5 GB, but I like to round it more to count is as 4 GB.
  10. Again because I am choosed ntfs as the partition format, this time we will be creating another disk image where the userdata will reside, a.k.a the data.img. For data.img size, the partition size I am using to install this PrimeOS is 32 GB and the PrimeOS system.img created is 4 GB rounded up roughly, I want to use all the left space on the partition as much as possible, then it is means the space left is 32GB - 4GB = 28GB. But I want to take extra measures just in case by substract it by 2 GB, so I only want to use 26 GB instead. So for the data.img size I want in MB is 26 * 1024 = 26624.
    Installation wizard data img size PrimeOS Dynabook R734/K
  11. After the data.img has been created, we won’t boot the newly installed PrimeOS yet, but we will add it first to the installed GRUB bootloader, in my case alongside installed Ubuntu MATE and Windows 10. Reboot my laptop back to BIOS Boot Menu (see step 4 above), unplug the installation media, reorder the boot priority back to prioritize hard drive (see step 5 above), then reboot to a Linux OS (in my case Ubuntu MATE).

Adding PrimeOS boot entry to GRUB

OS used: Ubuntu MATE
app used: Grub Customizer

Steps:

  1. Launch Grub Customizer app.
  2. Click “Paper plus” icon on the toolbar of Grub Customizer to add new boot entry to the GRUB.
  3. On the “Name” input, fill it with proper name, like “PrimeOS 2.1.0”.
  4. On the “Type” select, choose “Other”.
  5. Next, on the “Boot sequence” textarea, fill it with the boot script which I got originally from the Android-x86 project (this PrimeOS based on) with a little bit adjustments:
    Grub Customizer boot script PrimeOS Dynabook R734/K 
    set root='(hd0,3)'
    linux /android-2.1.0/kernel quiet root=/dev/ram0 androidboot.selinux=permissive acpi_sleep=s3_bios,s3_mode SRC=/android-2.1.0
    initrd /android-2.1.0/initrd.img
    • 0: It is the hard disk position where the PrimeOS installed, in my case I only have one hard disk, 0 means it is the first/main hard disk.
    • 3: It is the partition number where the PrimeOS installed.
    • android-2.1.0: The directory created at the root of the partition when PrimeOS is installed, where the PrimeOS files resides. We can get this value easily by browsing to the partition where the PrimeOS installed using a file manager.
  6. Click “OK”, then click “Save” on the Grub Customizer toolbar to save the boot entry to the GRUB bootloader.
  7. Restart our PC. The next time we reboot our PC, we should see the PrimeOS entry we just added in the GRUB bootloader menu.

Installing Nexus LiteOS 11 Superlite (Window 11 Mod) + Drivers on Toshiba Dynabook R734/K Laptop

Installing Nexus LiteOS 11 Superlite (Window 11 Mod) + Drivers on Toshiba Dynabook R734/K Laptop

1 comment

Nexus LiteOS 11 Superlite is a modded Windows 11 operating system created by a team named “The World of PC”. So on this post, I will share how I install this lightweight-ed OS on my Toshiba Dynabook R734/K laptop.

Nerdizen.xyz — Windows 11, the newest version of the most used Operating System (OS) from Microsoft was released on the 2021. Bringing new features and new looks while also new system requirements preventing it to be installed on old PCs (Personal Computer), including my Dynabook R734/K laptop.

But thanks to the modding community, there are lots of modded Windows 11 OS that mainly strips the system requirement check when installing it like processor requirements, TPM (Trusted Platform Module) check, Secure Boot check, etc. And the first modded Windows 11 OS I ever installed is the Nexus LiteOS 11 Superlite by The World Of PC.

Other than stripping the system and hardware requirements upon installing, Nexus LiteOS 11 Superlite also removed many minor features and bloatware of the Windows 11, making it faster and lighweight even for 4 GB RAM (and I proved the claim is right when running it on my Dynabook R734/K laptop powered by i3-4000M processor with 4 GB RAM).

Installing drivers on Nexus LiteOS 11 Superlite (Example on Toshiba Dynabook R734/K)

There are three sources I used to install drivers for my Toshiba Dynabook R734/K laptop on Nexus LiteOS 11 Superlite, they are:

  1. Windows Update / Microsoft server or Reviver Soft Driver Reviver app (main source / majority of drivers). Since Windows Update is disabled by default on Nexus LiteOS 11 Superlite, I prefer using Reviver Soft Driver Reviver.
  2. Dynabook website (Bluetooth driver). You can download the Bluetooth driver for Toshiba Dynabook R734/K from my Google drive backup at the end of this post.
  3. Auslogics Driver Updater app (missing minor drivers that was not found/detected using above sources).

Notes:

  • Per my own experience, don’t rely too much on driver updater apps. Use them strictly as necessary, especially Auslogics Driver Updater app to install missing driver only.
  • Touchpad driver for Toshiba Dynabook R734/K laptop can be installed by updating the driver with “mouse icon” in Auslogics Driver Updater.

If you have been followed my blog for quite some time, you may know I have shared some custom ROMs for ASUS ZenFone Live L2 X00RD. But this LineageOS 18.1 is made by the best builder of custom ROMs for ASUS ZenFone Live L2 Android phone so far in my opinion, which is techfanciers@Sourceforge.

Just like other custom ROMs build by techfanciers@Sourceforge, this LineageOS 18.1 is a native custom ROM, in other means it is not a GSI-based ROM. So expect more hardware features worked!

How to install LineageOS 18.1 ASUS ZenFone Live L2 custom ROM

Requirements:

  8. Done! Reboot our ASUS ZenFone Live L2 Android phone to start enjoying the LineageOS 18.1 custom ROM with Android 11!

Quick Review of LineageOS 18.1 ASUS ZenFone Live L2 custom ROM

For daily usage, I think this LineageOS 18.1 custom ROM is quite stable when I tried it on my ASUS ZenFone Live L2 X00RD Android phone, of course with some exeptions of small bugs which is for me can be tolerated moreover if we compare the tradeoff with using Android 11 ROM on such unpopular device like this ASUS Zenfone Live L2 Android phone.

On the appearance side, there are not much to comment as this is LineageOS, an Android ROM that stick as close as possible to the pure AOSP project ROM.

But like I said before from ROMs buit by techfanciers@Sourceforge, this is a native custom ROM (ported from ASUS ZenFone Live M2, if I remember correctly), most of the hardware features are working out of the box to even like Miracast and FM Radio.

From the performance side, I think there are also no problem when I was using this LineageOS 18.1 as my daily drive for common tasks like like browsing, messaging, watching videos on Youtubes, etc., everything went smooth on my ASUS ZenFone Live L2 X00RD Android phone.
