Dual boot

Dual boot Windows and Ubuntu

Dual Booting with Windows. In your Windows install, open Control Panel and head to “Power Options”. Select “Choose what the power buttons do”, select “Change settings that are currently unavailable”, then disable the “fast startup” setting. Note that Windows updates may occasionally turn this setting back on without asking, so if you are unable to boot into Pop!_OS, check this setting first.

Dual Booting Ubuntu and Windows With a SSD and a HDD

Preparation

On my Dell Precision laptop

• Disable RST/Intel Rapid Storage Technology. Go to BIOS and change SSD setup from RAID (or IDE) mode to AHCI.
  • You've got a single HDD/SSD set up in RAID (RST) mode, and the Ubuntu installer won't recognize your HDD/SSD until you switch your disk setting in the BIOS from RAID to AHCI.
  • AHCI vs IDE: What’s the Difference Between AHCI and IDE (screenshots)
  • What does AHCI Mode, IDE Mode, RAID Mode, & SATA Mean in the BIOS settings
• Turn off BitLocker on Windows C:\ drive.
  • See the instruction on ubuntu.com

My case

• /dev/sda - Windows
• /dev/sdb - bigdisk
• /dev/sdc - Linux

When I need to upgrade Linux,

• No need to unplug Windows SSD
• Run the live Linux (it's a little slow to show the first screen on my 2008 ECS P45T-A computer)
• Run GParted and delete all partitions on /dev/sdc
• Accept the default option to install Linux Mint alongside Windows 10
• Continue the installation

MultiSystem – Create a MultiBoot USB from Linux

• How to Install Multiple Linux Distributions on One USB using MultiBootUSB (Linux/Windows)
  • To test Boot ISO function, Ubuntu needs to run 'sudo apt-get install qemu'. See Virtualbox -> QEMU.
  • When select USB disk, it must be a partition (eg /dev/sdb1) instead of a drive (eg /dev/sdb). By default, MultiBootUSB will only show the drive but the drop-down list will show the partition if it has been created before.
  • I have installed ubuntu, linuxmint, manjaro-xfce, CentOS, tails.

Create customized ubuntu iso

• Cubic.
  • https://github.com/PJ-Singh-001/Cubic?utm_source=pocket_saves
  • https://www.ostechnix.com/create-custom-ubuntu-live-cd-image/
• Ubuntu Mini Remix (~200MB). Note that this is a live ubuntu which can't be installed even we can remaster it to include Desktop Environment, packages, et al. See this FAQ.
  • Ubuntu customization kit - linux.com howtogeek. The project has not been updated since 2013-01-16.
  • Ubuntu Builder - lifehacker. It looks the project is abandoned.
  • Customizer - quite information from its website. The manuals/user guide 3.x p46 talks about how to make the iso installable instead of just a live CD (e.g. apt­-get install ubiquity ubiquity-­frontend-­gtk). N.B. Installing ubiquity should be run once we have installed all software we want; i.e. if we want to install xfce4 we should install xfce4 before we install ubiquity. Also for some reason, Customizer crashed when I tried to create an iso if I have installed xubuntu-desktop, ubiquity and ubiquity-­frontend-­gtk.

Note that the Ubuntu Mini Remix by default contains only 3 repositories. We may want to add some more.

• http://askubuntu.com/questions/409607/how-to-create-a-customized-ubuntu-server-iso It gives a long instruction based on command line.
• http://razvangavril.com/linux-administration/custom-ubuntu-server-iso/ The instruction is organized and is very similar to the above.
• http://amjjawad.blogspot.com/2013/07/ubuntu-mini-iso-installation-process.html It does not talk about creating a customized iso. It talks about how to install Ubuntu from the minimal CD (~40M). The minimal CD will download the packages in the installation process.
