An operating system from the Windows NT family of operating systems from Microsoft, released in 2012 and the successor of Windows 7. Introduced UEFI as a replacement for legacy firmware/BIOS and required computer manufacturers to enable the "secure boot" feature.
Windows 8 is a consumer operating system of the Windows NT family for desktops, laptops, tablets and smartphones released by Microsoft in 2012. The server release is called Windows Server 2012.
The most obvious change in Windows 8 is the heavy focus on touch in the desktop user interface and the introduction of the Metro design language, that first debuted in Windows Media Center and Zune, but more commonly seen in Windows Phone 7.
OEM Recovery and Refresh Media
Microsoft officially offers users to download refresh media and reinstall an unmodified version of Windows themselves without needing to create recovery media from the OEM recovery partition. A complete hard drive backup with all partitions or creating the recover media is still recommended before installing Ubuntu or making other modifications.
UEFI and secure boot
Windows 8 is the first of the Windows NT line to require computer manufacturers to ship devices with UEFI and the secure boot feature to be enabled through its Windows Hardware Certification Requirements.
While installing Ubuntu with secure boot enabled is possible since 14.04 for LTS releases, non-distribution Kernel modules like proprietary graphics drivers, VirtualBox and other software that relies on
dkms will not work. The secure boot feature can be disabled from the Advanced startup menu in Windows 8 (see: How to access the UEFI firmware settings? (aka BIOS)).
For more details and known issues with UEFI have a look at the uefi tag wiki page.
- support for Advanced Format hard drives
- these were already supported with Windows 7 Service Pack 1
- support for USB 3.0
- built-in antivirus software
- thus not necessarily requiring 3rd party security application packages to feel safe, strengthening the statement that you don't necessarily need these in Linux either
