Last updated: April 24, 2024

Want to install Ubuntu on your computer but don’t have an USB drive on your hand? An open-source tool Tunic may help.

Tunic is a tool that can install Ubuntu or Linux Mint over or alongside an existing Windows install, straight from Windows, without requiring to boot from external media like a flash drive or making BIOS configuration changes.

Features of Tunic include:

  • Shrink C: volume to make space for Linux, so you can dual boot them.
  • Disables Windows fast start.
  • Provide tools to assist with freeing up space for Linux.

And, requirements include:

  • 64-bit Windows 10
  • Single drive hosting the C: volume
  • 4 GB RAM or higher.
  • At least 15 GB of free disk space
  • UEFI
  • Administrator user permissions
  • Internet access for downloading iso image.

As a new project, it may have bugs! BACKUP your data before getting started! For more about Tunic, as well as the download link, go to its project page in Github.

How to Install Linux Kernel 5.5 in Ubuntu / Linux Mint

Last updated: April 24, 2024

Linux Kernel 5.5 was announced two days ago. Linus Torvalds wrote on lkml.org:

“So this last week was pretty quiet, and while we had a late network update with some (mainly iwl wireless) network driver and netfilter module loading fixes, David didn’t think that warranted another -rc. And outside of that, it’s really been very quiet indeed – there’s a panfrost driver update too, but again it didn’t really seem to make sense to delay the final release by another week.

…”

Kernel 5.5 release highlights:

  • Support for the Broadcom BCM2711 SoC (Raspberry Pi 4).
  • New Logitech driver for G15 and G510 keyboard.
  • KVM support for IBM POWER secure guests/VMs.
