Create a Bootable USB on Windows for Any Linux OS from ISO File. From an ISO file containing Linux (almost any Linux OS distribution), you can create a bootable USB installer disk on Microsoft Windows easily. If you downloaded your favorite Linux Operating System, most likely, it will be an ISO file (archive, disk image). Software distributed on bootable discs is often available for download in ISO image format and is written on, or “burned” to, a CD, DVD, or a USB flash drive with any capable software. Use this guide to easily create an installer for your favorite Linux operating system (not larger than USB drive size) on a USB drive. Pendrivelinux provides easy method to install, boot, and run a variety of Linux OS distributions from a portable USB drive. Supported Linux operating systems are Ubuntu, Mint, Debian, Fedora, Open. SUSE, Puppy and many other Linux distributions. Not just the Linux, but it also supports creation of bootable USB disk containing non- Linux based software (e. Microsoft Windows Installer USB disk).

Create Bootable USB Disk Containing Linux Installer from ISOWe take example of Ubuntu that is widely being used. When you download Ubuntu, it will be downloaded in ISO format. Universal USB Installer can create a bootable USB drive containing Ubuntu installer, on Microsoft Windows. You can use that bootable USB to install Ubuntu on your PC. How Universal USB Installer Works. Download your favorite Linux operating system (In our case it is Ubuntu – ISO file). Download Universal USB Installer and run it (its portable and can run without being installed on PC) on PC. In case of Ubuntu, select Ubuntu in step 1, where it says ‘Select Linux Distribution’. In step 2, browse and open the Linux ISO file that you downloaded. Select your USB drive carefully. Go to computer to see the USB drive letter so that you may be able to correctly select the USB drive from Universal USB Installer. Click ‘Create’ button and let this software finish its task. After that you will have a Linux operating system ready to be installed or used from USB drive. You can also choose to format USB drive before creating bootable disk. Your USB drive must be Fat. Fat. 32 or NTFS formatted, otherwise your drive will not Boot. For Ubuntu Linux, you need a USB of at least 2. GB capacity. When you are done, your USB will show like this: Installing OS from Bootable USBChange the PC setting from BIOS and configure it to run from USB drive. Restart the PC and it will pick the installer or package from the USB drive to install or run Linux on your PC. Caution: If you are not familiar with the Linux file systems and you have not installed Linux before then you probably should get an expert’s help in installing Linux. In worst case, you might end up losing all your previous partitions during Linux install. In case of Ubuntu, read installation instructions carefully. It is not like FAT3. NTFS. You won’t just be selecting a single NTFS partition to install Linux on. You will have to determine root, bootloader and swap portions. DO NOT CHOOSE ‘REPLACE WINDOWS WITH UBUNTU’ BECAUSE IT WILL ERASE ALL PREVIOUS PARTITIONS. Always choose ‘something else’ and choose partition to install Linux on. DO NOT CHOOSE WHOLE HARD DISK FROM ‘DEVICE FOR BOOTLOADER INSTALLATION’. If your hard disk is empty and this is a fresh Linux install then do whatever you like. But if hard disk has already got partitions and data, be very careful. The BIOS/MBR Boot Process. Regardless of the computer or operating system, standard (“IBM- compatible”) desktop PCs and laptops all power on and start up using one of two ways: the traditional BIOS- MBR method and the newer UEFI- GPT method, used by the latest versions of Windows, Linux, and Mac OS X on newer PCs, laptops, and tablets. This article summarizes the process by which traditional BIOS PCs load an operating system, covering the basics and details of the BIOS, MBR, and bootsector. This article has been unofficially dubbed Everything you ever wanted to know about how your PC boots, part one. Overview of the BIOS/MBR Boot Process. In the diagram below, the boot sequence for all standard computers and operating systems is shown: As you can see, the boot process is broken down into several major components, each of which is a completely- separate subsystem with many different options and variations. The implementations of each component can differ greatly depending on your hardware and operating system, but the rules they follow and the process by which they work are always the same. Components of the Boot Process The BIOSThe BIOS is where hardware meets software for the first time, and where all the boot magic begins. The BIOS code is baked into the motherboard of your PC, usually stored on what is called an EEPROM 1 and is considerably hardware- specific. The BIOS is the lowest level of software that interfaces with the hardware as a whole,2 and is the interface by means of which the bootloader and operating system kernel can communicate with and control the hardware. Through standardized calls to the BIOS (“interrupts” in computer parlance), the operating system can trigger the BIOS to read and write to the disk and interface with other hardware components. When your PC is first powered up, a lot happens. Electrical components of the PC are initially responsible for bringing your computer to life, as debouncing circuits take your push of the power button and trigger a switch that activates the power supply and directs current from the PSU to the motherboard and, mainly through it, to all the various components of your PC. As each individual component receives life- giving electricity, it is powered up and brought online to its initial state. The startup routines and overall functionality of the simpler components like the RAM and PSU is hardwired into them as a series of logic circuits (AND/NAND and OR/NOR gates), while more complicated parts such as the video card have their own microcontrollers that act as mini- CPUs, controlling the hardware and interfacing with the rest of your PC to delegate and oversee the work. The POST Process. Once your PC has been powered on, the BIOS begins its work as part of the POST (Power- On Self Test) process. It bridges all the various parts of your PC together, and interfaces between them as required, setting up your video display to accept basic VGA and show it on the screen, initializing the memory banks and giving your CPU access to all the hardware. It scans the IO buses for attached hardware, and identifies and maps access to the hard disks you have connected to your PC. The BIOS on newer motherboards is smart enough to even recognize and identify USB devices, such as external drives and USB mice, letting you boot from USB sticks and use your mouse in legacy software. During the POST procedure, quick tests are conducted where possible, and errors caused by incompatible hardware, disconnected devices, or failing components are often caught. It’s the BIOS that’s responsible for a variety of error messages such as “keyboard error or no keyboard present” or warnings about mismatched/unrecognized memory. At this point, the majority of the BIOS’ work has completed and it’s almost ready to move on to the next stage of the boot process. The only thing left is to run what are called “Add- On ROMs”: some hardware attached to the motherboard might require user intervention to complete its initialization and the BIOS actually hands off control of the entire PC to software routines coded into hardware like the video card or RAID controllers. They assume control of the computer and its display, and let you do things like set up RAID arrays or configure display settings before the PC has even truly finished powering up. When they’re done executing, they pass control of the computer back to the BIOS and and the PC enters a basic, usable state and is ready to begin. BIOS Boot Handoff. After having configured the basic input and output devices of your PC, the BIOS now enters the final stages where it’s still in control of your computer. At this point, you’ll normally be presented with an option to quickly hit a key to enter the BIOS setup from where you can configure hardware settings and control how your PC boots. If you choose nothing, the BIOS will begin the first step in actually “booting” your PC using the default settings. Earlier we mentioned that an important part of the BIOS’ work is to detect and map connected hard disks. This list now comes in handy, as the BIOS will load a very small program from the first hard disk to the memory and tell the CPU to execute its contents, handing off control of the computer to whatever is on the hard drive and ending its active role in loading your PC. This hard drive is known as “the boot device,” “startup disk,” or “drive 0” and can usually be picked or set in the BIOS setup. The Boot Device. Regardless of whether the BIOS was configured to boot from a local hard disk or from a removable USB stick, the handoff sequence is the same. Once the BIOS POST and Add. On ROM procedures have completed, the BIOS loads the first 5. MBR, or the Master Boot Record. The Master Boot Record (MBR)The MBR is the first and most important component on the software side of things in the boot procedure on BIOS- based machines. Every hard disk has an MBR, and it contains several important pieces of information. The Partition Table. First and foremost, the MBR contains something called the partition table, which is an index of up to four partitions that exist on the same disk, a table of contents, if you will. Without it (such as on floppy disks), the entire disk could only contain one partition, which means that you can’t have things like different filesystems on the same drive, which in turn would mean you could never install Linux and Windows on the same disk, for example. Bootstrap Code. Secondly, the MBR also contains a very important bit of code known as the “bootstrap code.” The first 4. BIOS will load it and execute its contents as- is, kicking off the bootloader procedure. How small? Well, to put things in context, 4. Mi. B floppy disk – barely enough to fit any form of useful code – and way, way too small to do something as complicated as call up the operating system kernel from the disk. Given how tiny the bootstrap code section of the MBR is, the only useful purpose it can really serve is to look up another file from the disk and load it to perform the actual boot process. As such, this bootstrap code is often termed a “stage one bootloader.” Depending on the operating system, the exact place the bootstrap code searches for the “stage 2 bootloader” can change, but on Windows the stage 1 bootloader will search the partition table of the MBR for a partition marked as “active” which is MBR- speak for “bootable,” indicating that the start of the partition contains the next portion of the boot code in its starting sectors (also known as its “bootsector”). On a correctly- created MBR disk, only one partition can be marked as active at a time. So the job of the bootstrap code segment in the MBR is pretty simple: look up the active partition from the partition table, and load that code into the memory for execution by the CPU as the next link in the boot chain. Depending on the OS you’re loading, it might actually look up a hard- coded partition instead of the active partition (e. Ki. B of the partition, it might be the second Ki. B or 6 Ki. B starting from the 2nd multiple of the current phase of the moon) – but the basic concept remains the same. However, for legacy compatibility reasons, the MBR almost always loads the first sector of the active partition, meaning another only- 5. Boot Signature. On IBM- compatible PCs (basically, everything) the final two bytes of the 5. MBR are called the boot signature and are used by the BIOS to determine if the selected boot drive is actually bootable or not.
