With the announcement of the Ubuntu Phone OS I'd like to know what phone (and tablet) models are supported at this time.  Note from foss &amp; Oli: We are making this the master question for all future "Will this work on &lt;insert random tablet/phone/device here&gt;?!" questions

My computer no longer boots Windows or the installed operating system. Instead, I may get this error:  PXE-E61: Media test failure, check cable -or- Check cable connection!  PXE-M0F: Exiting PXE ROM.   and/or one of the following messages or similar:  Operating System not found  No boot device available- No bootable devices--strike F1 to retry boot, F2 for setup utility  No bootable device -- insert boot disk and press any key  No Boot Device Found. Press any key to reboot the machine  Default Boot Device Missing or Boot Failed  Reboot and Select proper Boot device or Insert Boot Media in selected Boot device   What does this mean and what can I do?     This question comes up often and the answers are usually the same. This post is meant to provide a definitive, canonical answer for this problem. Feel free to edit the answer to add additional details.

I tried to install Android's ROM and got ERROR 7, then I wiped out cache, data, internal storage, where was twrp.apk installed. After that I cant get into boot menu (with Install, Wipe... buttons). Then I copied twrp to the phone: sudo fastboot flash recovery &lt;twrp.img&gt; Tried versions 3.2.1-0 and 3.4.0-0, because I heard for certain phone (I have Xiaomi Mi4) it's necessary to use proper version, though I don't know which. What's going on now: I can successfully can get to the nice splash screen using Volume Down + Power, then on my PC I give sudo fastboot reboot command and press Volume Up + Power and here is the problem: It has no effect, it just keeps rebooting (I see only Xiaomi's logo).

My ubuntu boot screen shows up in a strange low resolution, almost text mode, instead the usual and sleek white "ubuntu" over dark background. It's not a big issue because when GDM loads everything becomes ok, but If there's an easy way to fix it I would like to give it a try.

I was not aware of booting mode and installed ubuntu on my new x64,4 gb ram, Acer ES15 laptop in legacy mode. I read about the feature of uefi mode and would like to switch to uefi. When I boot on legacy mode, ubuntu loads up and system works fine, but when I change my bios setting to uefi it says no bootable device found. Should I install ubuntu again using uefi mode after erasing data? Will that work?.... Is there any other way to get to uefi mode or I need to format and then install ubuntu again using uefi bios mode? Please, help.

What is the difference between:   Unlocking the bootloader (prerequisite for doing many, though not all, other things below) Rooting Jailbreaking ROM NAND and Nandroid Operating System Mod (e.g. CyanogenMod) Recovery (ClockworkMod, Amon Ra) Custom Kernel (e.g. LeshaK's kernel) Firmware Driver Over The Air (OTA) update Fastboot SIM unlocking Flashing SPL (Second Program Loader)   (any other often-confused terms that I've missed?)

I am trying to install Ubuntu 19.04 (or any other Linux distro) on a new HW consisting of Ryzen 3900X CPU, Gigabyte Auros Master X570 motherboard and AMD Radeon Vega 64 GPU. On installation startup from a bootable USB drive, it shows "Ubuntu" with 5-6 dots underneath representing installation progress. However, it is perpetually stuck in that mode. When I press ESC, it shows dozens of lines of failure messages.  I searched internet for a clue as to what is causing this and to fix it with no avail. Some suggest Gigabyte motherboard is not fully compatible with Linux. I have tried the same with Manjaro but again similar failures. I have tried changing IOMMU to "enabled" but did not work either.  Can anyone help? Although I have used Ubuntu, my technical knowledge is very limited in attempting to resolve the issue.   If other ditro will work, I am willing to use it. But Ubuntu is my preference.

I recently tried booting into the Grub2's menu entry "Ubuntu GNU/Linux, with Linux 3.2.0-24-generic-pae (Recovery Mode) just to see what was there.  It booted successfully, but I had no idea what to do after I was there.  My question is where can I find some documentation on the recovery mode and what to do if I truly needed to be there.  I'm running Ubuntu 12.04.

I can't boot via USB after installing Ubuntu.   Yes, the BIOS lists USB, but it is disabled.  Yes, USB is at the top of the boot priority in the BIOS, but it is disabled.  Yes, user Da1T, I'm looking in the BIOS.   Burning an image to disc is a waste of time and money.

Canonical has recently announced , which is Ubuntu with a specific interface for mobile devices.  Where can I get phones with this version of Ubuntu pre-installed? If no devices are available yet, where can I pre-order one?

I installed Ubuntu 11.10 on a newly bought Lenovo ThinkCentre Edge 71 (model: 1577-G3G) with EFI boot enabled. I opted for the Use Entire Disk option. Even though the installation process went without any problems/errors, when rebooting it now just gives me:     No bootable operating system. Insert bootable disk and press any key...   I figure this is because of EFI.   Regression:   I have checked the System Setup (F1 during POST) to find a BIOS option to disable EFI/UEFI boot, however, there is no such option for this machine. This might be caused by a "Secure Boot" feature in the BIOS. The hardware vendor does not know of any such "secure boot" setting in the BIOS that would prevent Linux from booting. Lenovo support did not know anything about a BIOS setting called secure boot. They also did not know of any limitations that would prevent Linux from booting. The  does not mention EFI, UEFI nor secure boot.   How do I install Ubuntu on a machine with EFI? - Or, since Ubuntu is probably already installed: how do I make it boot Ubuntu?

Are there any technical or others reasons why Android is still a firmware and not an OS which can be just installed without a lot of hassle?  Why there is no universal image which could detect appropriate drivers (kernel modules), partition NAND in some standard way and configure boot loader to boot updated OS version?  What stops Google from making a real (less firmware-like) OS (an OS for small ARM, x86 etc. devices)?

I would like to pre-install Ubuntu on a computer for someone. I may want to customize it for them, but in the end they need to be able to choose a username, password, etc. when they first boot it up. (Also called an OEM install).  How do I do this?

Are there any risks to manually flashing a stock or custom ROM?   Does it have the potential to brick the device? Will it void my warranty? Will I stop getting updates? Anything else I should be aware of?   (See also: )

I am a new user for Ubuntu. I downloaded 13.10 yesterday and made a bootable USB with universal USB installer on my Lenovo IdeaPad Z580 laptop which is now using UEFI; everything appeared OK.  When I booted from the LiveUSB I got the choices of trying or installing Ubuntu but both of them keep giving me these error:  [ 1.929082] kernel panic-not syncing vfs unable to mount root fs on unknown-block (0.0)   Please tell me what is going wrong?

I'd like to build a version of Ubuntu that has absolutely no ability to recognize any USB device inserted. Is this possible?  There's the issue that mouses and keyboards nowadays are connected via usb, so I wonder if it's possible to recognize these but not everything else.  In the end it's a security measure, so different solutions to achieve this goal are also welcome.
