Created a bootable USB from an iso-file with  sudo dd if=./ubuntu-18.04.3-desktop-amd64.iso of=/dev/sda1 bs=8M    using  BIOS does not see this USB. Did Fedora 31 mess up my BIOS and what can I do?

Downloaded the Ubuntu 16.04.2 .iso install disk and flashed it onto a USB stick.  Booting on the USB stick, there is no memtest86+ option (along with "Try Ubuntu").  Is there a way to add it to the install options?  (it's for a UEFI boot PC running normally Windows, its owner does not want to install Ubuntu. "memtest86+" is completely free (unlike "memtest86"), but is quite old, and does not offer a UEFI boot - this is why having it within the Ubuntu options makes things easier)

I've created a 15.10 Ubuntu USB drive and booting off it with an ASUS Rampage IV Black Edition motherboard, I get:  Ignoring BGRT: invalid status 0 (expected 1)  and then nothing. I've become really frustrated trying to get a stable BIOS config with this motherboard (every boot produces an Overclocking failed! message and none of the even low-key default options avoid this message with an i7 3930K - this board rules as the hardest motherboard I have ever configured in the last 10 years!) and now it can't boot a vanilla 15.10 USB drive. I'd really value some help..  EDIT  I found the solution. See below.

I'm currently running Ubuntu 12.04 and want to completely format my laptop so I can install Windows 7 (replace Ubuntu).   When I put in my bootable USB with the OS it just shows a black screen with a white blinking cursor on the top left corner. I wait for hours (to be specific 5 whole hours) waiting for something to happen but I get nothing, so I pull out the USB and my Ubuntu 12.04 loads up.  Repeated this several times with putting different boot priority options on top-est that relate to USB but the results are same. I go and visit some sites on the net like this  that say I have to zero out my hard drive.   My question is how?  Note: Erasing out all my data is no problem cause I have nothing important to backup.  If I have to lose my primary OS (Ubuntu 12.04) in the process I am ready to as my aim is just to install Windows 7 successfully. Please don't answer that there is something wrong with my USB or my USB reader/port/hardware or the content inside the USB cause they all works fine on my brothers PC as it boots up flawlessly.

When I use my laptop, I have no trouble at all accessing the BIOS and changing things like the boot order.   However I recently got an iMac and have found that not only do the usual keys not get me to the BIOS, but when I find one that gets me to a boot menu (holding option when booting up) it won't recognize my USB boot drive of Ubuntu!  How can I access the BIOS menu like I could in a PC?

I had Ubuntu 12.04 Beta installed on my computer. When 12.04 was finally released, I made a bootable USB Flash Drive using Startup Disk Creator.  Then I decided to check if this drive works properly and to reinstall the system on my desktop. I must add, my desktop behaves a bit strange when it comes to bootable USB's, it recognizes them as HDD.  In BIOS I changed priority of boot so USB Flash Drive (recognized as HDD) was first. Successfully booted, I installed Ubuntu. Everything worked fine, but...  Now I cannot boot from my real HDD. Every time I want to boot, I put the USB Flash Drive into my computer, boot, safely remove it and everything works.  What do I need to do to repair boot?

What I want is to create a bootable pen drive that shows GRUB menu and I can select any of the several bootable systems from there to install/run. I have several ISO images that I want to install in the USB like Ubuntu, Fedora, System Rescue CD, Windows XP and Windows 7 (The windows versions are optional, mostly am looking for a multi installer for Linux distros, specially Ubuntu version)  The default Startup Disk Creator only works with Linux Images and only 1 at a time (At least for the mean time. If it allows more systems and multiple ISOs it would be awesome)  What method exists that I can use step by step to create a bootable USB Drive with multiple images than can be booted from the USB and selected from GRUB. It must support Windows Images and Linux Images.  Alternatively, is there also a way to have multiple versions of the Ubuntu installation ISO on same USB Drive, such as, when booting from it, I get to choose what Ubuntu version and architecture to install, for example:     BOOT MENU   Ubuntu 12.04 32 Bit   Ubuntu 12.04 64 Bit   Ubuntu 12.10 32 Bit   Ubuntu 12.10 64 Bit   UPDATE: Wanted to add that the English version for the post mentioned by daithib8 is here:

I have made a BOOTABLE USB installation of Ubuntu 13.04 using . I also have Windows 8 on separate partition. After I finished installing Ubuntu 13.04 from the USB, it went straight to Windows 8 without Grub showing to ask me to select an operating system, how can i fix this ? I don't have UEFI or secure boot.

I want to use dd to clone my running Linux OS which is installed on a PI4 MicroSD 64GB media, to an image.  Because it is a Raspberry PI I cannot (easily) boot from a USB stick and run the job with the PI4 OS not running. If I do such a job, using a console login, can I restore later without issue?  Essentially can dd create a proper, restorable image of the main drive (/dev/sda) from a terminal session from within a running system?

I want to create liveUSB on part of my flash stick. I made a partition with GParted and downloaded .iso file of Ubuntu 19 from the official website to mount with gnome-disk-utility.  I noticed that the iso file has "amd64" in the name. But I intend to use this USB not only on amd computers!  Is that important? Will the live USB work on PC with Intel/other processor?

I'd like to have Ubuntu installed on a USB stick, that I could plug in (almost) any computer and boot from it, and that I could use (almost) normally, as if it was installed on that computer. I'd also like to have a data partition on it that could be used by (almost) any computer, mostly to store some portable apps, just in case.    I've been told that if I installed Ubuntu in BIOS mode, I wouldn't be able to boot from a computer in UEFI mode, and vice versa.  Since I'd like to be able to boot on any computer, it's a big problem.  What can I do to be able to boot on computers in BIOS or UEFI modes in my case?  I've been searching for solutions but most of them are for specific needs that are different than mine, so it's difficult to extract the minimum requirements from those solutions to apply them to my problem.  Is there a simple, "clean" and quite generic solution to this problem?  I'd appreciate some explainations about the reasons why a specific solution is good or a specific step is needed.    My current setup:   USB stick:  OS: Xubuntu 16.04 i386 installation: full install (from a Live USB built with Rufus) drivers: none proprietary file systems:    partition table:    2: , /boot/efi, 128 Mio, FAT32, [boot,esp] 3: , 128 Mio, HFS+ 4: , 2 Mio, [bios_grub] 5: swap, 512 Mio 6: , /, 24 Gio, ext4, defaults,errors=remount-ro,lazytime,commit=60 1: , /media/data, ~3.6 Gio, FAT32, defaults,lazytime,check=strict  RAM:   /tmp, tmpfs, defaults,nosuid,nodev,noexec,mode=1777   swap:    vm.swappiness=5 swap partition: 512 Mio, for emergency zRAM swap files:    /var/swap/hib.swp: same size as RAM, for hibernation, generated by a script at startup /var/swap/opt.swp: if needed, generated by a script   overprovisioning: ~5.6%   built-in: ~1.2 Gio (apparently) added: 512 Mio  scheduler: deadline

I've downloaded en_windows_10_education_version_1703_updated_march_2017_x64_dvd_10189297.iso from the Windows imagine portal. I'm reading that the image can be booted from a usb so I've tried using dd.  With the following command:  sudo dd bs=4M if=en_windows_10_education_version_1703_updated_march_2017_x64_dvd_10189297.iso of=/dev/sdc  status=progress   That doesn't work when I try to boot into the usb, so I also tried replacing /dev/sdc/ with /dev/sdc1.  My computer is setup to first boot with utfi and then legacy.  Is there something else I can try to get this working?

I accidentally issued some commands I thought were safe in the terminal, and I ended up with no System Settings and lots of other missing functionality, but the OS still boots normally. I've decided I want to install Lubuntu instead of fixing Ubuntu for a fresh start and since my laptop is running on a 1GHz dual core AMD CPU.  I created a bootable USB as I usually do and placed Lubuntu 17.10 amd64 using Rufus 2.14.1086. I have GRUB that was installed with Ubuntu upon first install I still have Win8.1 which I still want to keep.  PS: I also tried creating a startup disk from Ubuntu  The question is: How can I boot from USB with GRUB2 so I can overwrite Ubuntu?

I have an older i386 Sony Vaio desktop PC where the BIOS only allows boot from floppy, CD or very specific USB device types, none of which seem to recognize USB flash drives for some reason. Floppy is not an option because the drive no longer works and I have no media for it if it did. I've tried assorted CD and DVD drives, the CD drives all give read errors and DVD drives all say "unsupported emulation".  My next possible option that I would like to try, is to install the hard drive into another machine as a second HD and figure out a way to format it and save an Ubuntu installation to run from that HD once it is moved back into the target machine. IS this possible and if so, how would I go about doing so? The currently running machine uses Windows XP.
