There are multiple desktops available for use with Fedora. Each has a slightly different look and feel and offers varying levels of customization. You can use the Fedora Workstation image, which comes with the GNOME desktop by default, and then change your environment afterwards by installing additional packages, or you can download a spin image which will give you a different environment out of the box. Visit Fedora Spins for more information.

On live images, you can include a feature called a persistent overlay, which allows changes made to persist across reboots. You can perform updates just like a regular installation to your hard disk, except that kernel updates require manual intervention and overlay space may be insufficient. Without a persistent overlay, the stick will return to a fresh state each time it is booted.
The command with --bootstrap takes about half an hour to run on a four core machine. It compiles quite a bit of software, which it installs into your chroot, and downloads some additional items (around 300MB). While it is building you will see a regular update of the number of packages left to build. Once the command finishes, the chroot will take up total disk space of a little over 3GB.
The next step is to take the disk image and write it to some form of external media so that you can boot the computer into that media and then install the operating system. Most commonly the installation medium consists of either an optical disk such as a DVD, or USB flash drive.
All recent Intel-based Chrome OS devices (starting with the 2013 Chromebook Pixel) feature a Legacy Boot Mode, designed to allow the user to boot Linux. Legacy Boot Mode has a dedicated firmware region, RW_LEGACY, which is designed to be user-writeable (hence the 'RW' notation) and is completely separate from the ChromeOS portion of the firmware (ie, it is safe to update and cannot brick the device). It is enabled by the SeaBIOS payload of coreboot, the open-source firmware used for all Chrome OS devices (with the exception of the first generation of Chromebooks and a few early ARM models). SeaBIOS behaves like a traditional BIOS that boots into the MBR of the disk, and from there into standard bootloaders like Syslinux and GRUB.
You can download the google chrome OS ISO Document for Windows by accessing the link below. Also, make sure that you have enough back up before you proceed with the same. There are a lot of duplicate ISO images on the market and it is best to download the same from a trusted source.
(except, edit the *'s to complete the filename.)This will "burn" the Ubuntu disk image to your USB stick, as if it were a CD. In fact, it basically turns the USB stick into a CD, albeit one that runs significantly faster than your average optical drive.
After creating the virtual machine, its time to assign the downloaded ISO image of CR OS Linux to Virtualbox. For that select the created Virtual machine and select the Settings option from the Menu Vbox.
Under the settings, go to Storage option and click on the Empty CD icon. Then on the right side again click on another CD icon as shown in the below image. A pop-up options menu will open, select Choose Virtual Optical Disk File option and select the downloaded Cr OS Linux ISO image.
Once the setup and installation completed, first remove the Cr OS Linux ISO image from virtual disk. To perform this right click on the CD icon given at right bottom side of the Virtualbox and select the remove disk from virtual disk option. A pop-up will appear, choose the ForceMount option.
Once the ISO image ejected, click on the Machine and select the Reset option to reboot the machine. And this time the Cr OS Linux will boot from the VirtualBox hard disk.
Ideally, a persistent Live USB is a copy of the installation DVD. This, therefore, means that the files in the original ISO remain as they are. Updates and future installations are saved in the space designated for storing the changes. Say you update your chrome. In a standard installation, the old one is replaced. Still, in the persistent installation, the old one stays. The newer version is located in the persistent virtual disk (within the USB), thus taking up extra space and sometimes creating issues, for instance, kernel updates. Now, when you install Ubuntu from this Persistent copy into another hard drive, the original version of chrome in the DVD image will get installed.
For the USB image:Extract the archive. It will extract to a folder calledChromeOS-Vanilla-4028.0.2013_04_20_1810-r706c4144Inside this folder you will see a single file:ChromeOS-Vanilla-4028.0.2013_04_20_1810-r706c4144.img.This is the raw disk image you need to write to your USB diskI used the PCLinuxOS utility ddcopy to successfully write to a 16 GB drive.I would imagine using Rufus, Etcher, or similar should work as well from Windows-whatever (XP to Win-10, anyway).Good hunting. Be sure you have a network connection when you first boot.
where: is the device the USB key is assigned to. Use the base device (ie. /dev/disk2) not a partition designation (ie. /dev/disk2s1). is the file path for the input image file. (E.g: /Downloads/memtest86-usb.img)
I think there is a misunderstanding here, this looks like the exact kind of bootkit that Secure Boot was designed to prevent and that it does prevent it. The bootkit attacks the kernel by disabling module signature checking as the firmware loads the kernel image off disk. Presumably later in the boot process is a kernel module which loads and hides the bootkit and all evidence of its activity.
No matter how you do it, the physical machine must be safe from anyone untrustworthy. The critical stuff should be encrypted & hashed just in case. It should NOT be connected to Internet. Transfer files to and from using a simple non-DMA link (home-made data diode, anyone?). Keep copies of everything downloaded from internet, with hash and signatures, on read-only memory (CDROMS, preferably, using diff PC). Optionally put the signing key in an encrypted volume with very strong password, only opened [into RAMdisk] during the signing phase itself.
Also, sometimes you can get free security benefits at high performance. An example is how one of you was going to check a bunch of files for modifications. The dates might lie, so your software would probably hash every file & compare hashes to trusted baseline copy. Alternative: make a trustworthy system image, save it to hard disk as a whole image, & hash that image. Next time, you just have to hash/check one big file, then load it. Simple, eh? 2ff7e9595c
