Windows 10 bootable flash drive without uefi. Bootable USB stick UEFI GPT or UEFI MBR in Rufus

During the installation of clean Windows 10, difficulties may arise due to the appearance of motherboards with UEFI instead of BIOS and an ambiguous structure hard drives, such as GPT. If motherboard works on UEFI BIOS, we will show you how to install Windows 10 in this article.

Specifying Pre-Installation Options

First, find out which interface the motherboard is using:

  • standard BIOS;
  • or the new UEFI.

You can find out by finding information about the motherboard on the Internet. Also, UEFI differs from BIOS in terms of external design- looks like a more advanced one (beautifully designed, advanced settings, touchpad or mouse support).

  • MBR (Master Boot Record);
  • GPT (GUID Partition Table).

The ability to launch and install a bootable flash drive or DVD-R / RW will depend on the structure of your hard drive.

To find out the style, go to:

  1. RMB My Computer → Manage.

  2. RMB On disk → properties.

  3. Volumes tab → If the values ​​are blank, click Populate.
  4. Define section style hard drive.
  5. The GPT style partition looks like this.

Installing Windows 10

After finding out which BIOS the motherboard uses and which hard drive structure, we will highlight 3 ways to install Windows:

  1. Using classic BIOS, to a disk with MBR partition style.
  2. Using UEFI (EFI), to a disk with MBR style.
  3. Using UEFI, to a disk with a GPT partition style.

If you use the Rufus program to create a bootable USB flash drive, below is an example for creating a USB flash drive with the necessary settings.

With Classic BIOS, MBR

This is the classic way to install an OS. Insert the disk/flash drive into the drive/USB socket. When the computer boots up, enable the BIOS:

Using UEFI, MBR

With modern graphic design UEFI, choosing to boot from a flash drive/DVD-R is even easier than with the old BIOS interface. The UEFI interface supports installation on MBR and GPT disks, you just need to correctly specify the boot priority (see figure).

After choosing a priority, restart your computer and start installing Windows.

Using UEFI, GPT

The only useful property that the GPT structure gives to the average user is support for system disks with sizes of 2.2 TB or more. Otherwise, its use brings more problems than benefits. If an OS is not installed on a large hard drive, then it can have any structure.

Hi all! In the previous article, we looked at creating a bootable USB flash drive for installing Windows 10 on a computer running a UEFI BIOS without additional software. The method proposed earlier is very simple and does not involve installing any programs, but it will only work if the creation and subsequent installation process will be performed on a computer with a UEFI BIOS. This option is not suitable for other users, and therefore we will look at how to make a bootable Windows 10 USB flash drive in Rufus.

This program is good because it supports UEFI mode, which makes it possible to install the Windows operating system on a computer, regardless of whether it is running a UEFI system or an outdated BIOS. In addition, the Rufus product has proven itself for a long time from a positive point of view, it has a Russian interface and a large number of thank you reviews.

You can download the latest version of Rufus for free on the official website. It should be said that the Rufus utility does not require installation and can not only format and create bootable disks, but also flash the BIOS from under DOS, work on a system that does not have an installed OS ...

Create a bootable Windows 10 flash drive in Rufus.

I mean that you have already downloaded the utility from the link provided above and the system or already in this format. If both, then both are, then run the program as an administrator. Right-click on the shortcut/file and select "Run as administrator" from the context menu.


In order for the bootable Windows 10 flash drive you created to work under UEFI, it is imperative to set the parameter in the “File system” field in FAT32 format in the program. If you have a regular BIOS, then set the file NTFS system. Please also pay attention to the drop-down list "Partition scheme and system interface type". Here you can choose one of two standards for placing tables on the hard disk.

  • MBR (Master Boot Record) - master boot record
  • GPT (GUID Partition Table) - GUID partition table

The second standard on the list has replaced the first, and it is part of UEFI, which replaced the old and inconvenient BIOS. The main advantages of GPT include:

  • Supports hard drives larger than 2.2 Terabytes (maximum 9.4 Zettabytes), and MBR works with drives up to 2 TB.
  • Support for up to 128 partitions on a disk, and MBR works with 4 partitions.

In GPT, one can also note the high reliability, which is achieved by duplicating partition tables in several areas of the disk and cyclic redundant parity check (CRC). Due to this, the partition does not “fall” after the first sectors of the disk are damaged. However, you need to remember that booting Windows x64 from GPT disk is possible provided that the UEFI system is used. This is what UEFI looks like:

As I said, it replaced the good old BIOS and has a more convenient and structured interface, support for the Russian language, a mouse ...

First of all, in the Rufus utility, you need to select the inserted flash drive as the device and select the ISO image type as the parameter and immediately specify the directory where you have the image with Windows 10. For guidance, you can use the examples below.

So, if your computer is running UEFI, then select the FAT32 file system and set the partition scheme to “MBR for computers with UEFI” or “GPT for computers with UEFI”. The choice depends directly on the format in which you have HDD, but if you wish, you can convert its markup with a specialized program without losing information.

If the computer is running a regular BIOS, then select NTFS for the file system, and set the partition and system interface type to "MBR for computers with BIOS or UEFI".

Before pressing the "Start" button, you can, if you wish, immediately check the flash drive for bad blocks. To do this, mark the required item in the program. After you are warned that the flash drive will be formatted and you confirm your consent, the process of creating a bootable flash drive will begin.

    What nonsense are you writing?

    2019-04-03T13:08:46+00:00

    That is, a bootable USB flash drive is created without errors, but it can not be installed. Right? If so, what is the error message?

    P.S. I tested the operation of the Rufus program on a licensed build of Windows both under UEFI and BIOS - everything worked fine.

Given the fact that BIOS is gradually being replaced by UEFI, the question is how to make a bootable USB flash drive (or other USB stick) for the latter option becomes quite relevant. This instruction shows in detail how to create a bootable UEFI USB flash drive to install Windows 7, Windows 10, 8 or 8.1 using the distribution operating system in an ISO image file or on a DVD. If you need an installation drive for 10, I recommend more new instruction.

All of the following is suitable for 64-bit Windows versions 7, Windows 10, 8 and 8.1 (32-bit versions not supported). In addition, in order to successfully boot from the created drive, temporarily disable secure boot in your UEFI BIOS and also enable CSM (Compatibility Support Module), all this is in the Boot settings section. On the same subject:

The next step is to copy all the files from the Windows 10, 8 (8.1) or 7 distribution to the prepared flash drive. For novice users, I note: you do not need to copy yourself ISO file if you are using an image, its content is required. Now more.

If you are creating a UEFI USB drive on a Windows 10, Windows 8 or 8.1 computer

In this case, if you have iso image, mount it in the system, to do this, right-click on the image file and select "Mount" from the menu.

Select all content virtual disk, which will appear in the system, right-click and select "Send" - " Removable drive”(if there are several, then indicate the one that is needed).

If you do not have a disk image, but installation disk DVD, copy all its contents to a USB flash drive in the same way.

If you have a Windows 7 computer

If you are using Windows 7 on your computer and you have some kind of image mount program installed, such as Daemon Tools, mount the OS distribution image and copy all its contents to a USB drive.

If you do not have such a program, then you can open the ISO image in an archiver, for example, 7Zip or WinRAR and unzip it to a USB flash drive.

Additional step when creating a bootable USB flash drive with Windows 7

If you need a bootable UEFI flash drive to install Windows 7 (x64), then you will also need to do the following steps:


Before you install Windows 10 on new computer, which has a motherboard that supports a modern API called UEFI, you need to understand the basic concepts in order to get an idea of ​​\u200b\u200bwhat you have to deal with.

Having bought a new computer / laptop that supports UEFI, it is strongly recommended to immediately convert the table of its hard disk to GPT due to the many advantages that we will consider below, and only then install Windows 10 on it and copy any data.

What do all these abbreviations mean?

The outdated API, which ensured the interaction of the operating system with the hardware and transferred the first reins of control after the hardware was initialized, was replaced by the UEFI interface. The UEFI features that are important for a Windows 10 user are:

  • support for the GPT partition scheme - we'll talk about it later;
  • availability of services, one of which is necessary for Windows boot 10, and the second is used in Linux to store dumps, which record information about the problems that arose during the last shutdown of the PC;
  • modular architecture - installation of own (downloaded from the Internet) drivers in UEFI is implemented here. They are needed, for example, to gain access to the file system on a computer without an installed operating system;
  • supports a hardware-encrypted hard drive or logical drive;
  • UEFI is characterized by increased performance compared to BIOS;
  • works only in 32-bit and 64-bit mode, does not support 16-bit operation;
  • integrated download manager - can add its own boot menu items.

GPT- new standard placement of file tables on physical media, which came as a replacement for MBR. Unlike its predecessor, released to the masses back in 1983, GPT supports any hard drive larger than 2 TB (when using MBR, there is simply not enough address space to address all sectors), it can work with more than 4 active volumes and 128 partitions on one physical medium. GPT also stores multiple copies of boot data in different places on the partition, which is why using this file storage standard, you can recover damaged boot sectors much faster.

Drive preparation

Installing an operating system on a hard drive always starts with proper preparation. In our case, this is downloading a suitable image and deploying it on a USB flash drive. Consider the process with the assumption that the ISO is on the computer, and the Rufus application latest version already started.

We will use Rufus due to its ease of use and the absence of unnecessary menu options.

  • We select a flash drive that will act as a carrier for the Windows 10 distribution.
  • In the second drop-down menu, be sure to select GPT for a PC with UEFI.
  • It is better not to change the file system and the volume of the cluster - these parameters do not matter for the installation of the operating system.
  • We activate the quick format option so as not to wait ten minutes.
  • Check the box next to "Create boot disk” and click on the drive icon.
  • Select the image with the Windows 10 distribution and click "Start".

Converting partitions using OS tools

Windows 10 allows you to convert an MBR partition to GPT using the standard Disk Management tool.

  • You can call it by executing the "diskmgmt.msc" command or the "Start" context menu.

  • We select each hard drive and delete it using the context menu.

  • Through context menu hard drive, we call the command "Convert to GPT disk".

Note that it will become active after all volumes have been deleted, and if the running Windows is not on the media whose table you want to convert.

The conversion will take a dozen or two seconds if the disk does not have bad sectors. After that, disk partitioning becomes available and Windows installation 10 to its active partition.

Installation problems

If the installation of "dozens" on the hard disk stopped with an error stating that Windows installation 10 in UEFI system to MBR partitions is not possible, you must convert GPT to MBR to continue. The problem is faced by most users who did not perform the conversion before starting the installation of the OS.

This is done using a set of commands executed by .

  • To convert a disc, you need to restart your computer, and in the installation program, when the "Install" button appears, click "System Restore".

Keep in mind that following the instructions in the next step will clean your hard drive of all information and convert its partition tables to the new GPT standard, making it impossible to recover anything stored on the hard drive before conversion.

  • After opening the command line, sequentially enter the following chain of system commands into it:
  • diskpart - launch a utility for working with partitions;
  • list disk - visualization of the list of volumes in order to select a future system disk for conversion;
  • select disk X - select the desired volume;
  • clean - cleaning the active partition numbered X;
  • convert mbr - convert mbr partition;
  • create partition primary size xxxxxxx - create a new partition of the size specified in bytes;

When entering the volume size, keep in mind that 1 GB = 1024 megabytes, so to get a 50 GB disk, its size must be doubled by 1024.

  • active - make it active;
  • format fs=ntfs quick - perform a quick format in ntfs;
  • assign - the disk will be labeled with the first free letter of the English alphabet, starting with "d";
  • exit - exit from the command line Windows strings 10.

  • Click "Refresh" to re-recieve fresh information about the disk and its partitions.

If Windows installation 10 on the GPT partition was not implemented, and a familiar window appeared, in addition, several conditions must be met:

  • a 64-bit system must be installed;
  • the computer must be turned on in U mode

Most likely, setting the "tens" is impossible due to the second factor.

  • To solve it, you need to go into UEFI, which is done mainly with the F2 (for laptop) or Del (for PC) keys.
  • We find and activate (set the value as "Enable") the UEFI boot function.

Usually, it is located in the BIOS Features or BIOS Setup section.

  • We switch the SATA operation mode to AHCI instead of IDE mode. Most often, changing this option is not required, but it should be checked just in case.

  • We save the new settings.

IN various versions UEFI settings options can be located in different sections and even have different names.

After that, installing Windows 10 on a partition with a new standard for placing file tables is carried out as normal installation"tens".

Friends, everyone Have a good mood! The reason for writing an article on the topic "creation boot Windows flash drives 10 on UEFI" was the purchase of a laptop by my parents. They took it in installments in one famous trading network. So, initially it goes in the FreeDOS state, that is, nothing is installed at all.

But for additional fee, which is a good third of the cost of the laptop itself, good managers are ready to install licensed Windows and some modest package additional programs. Oh yes, and the warranty will still apply. And with a self-made installation, it generally does not seem to exist.

But as it turned out, there is an official method of creating one from Microsoft.At how it is very simple and suitable for both official users who have a key, and for pirates with all sorts of activators and keygens. For the success of the whole operation, we only need a USB drive with a capacity of at least 4 GB.

Therefore, let's no longer pull the cat by the balls of the ears, let's get down to business. And it all starts with the fact that you immediately need to go to the official website of the above company at this linkto download the utility Media Creation Tool to create the much-needed bootable USB flash drive with Windows 10.

At the first stage, we agree with the license and click "Accept".

Then select the item "Create installation media".

After that, we will be asked to select the language, version and bit depth of the operating Windows systems 10. Since the new laptop has a 64-bit processor, I select the appropriate value in the "Architecture" column.

At the next step, an ambush awaited me in the form of insufficient space on system drive C. Had to urgently size it. As you can see in the screenshot, you need at least 8 GB free space. so have it in mind.

Then a window will open with a choice of USB-drive. Mark it and click Next.

And now, my friends, it will be necessary to wait quite a long time. As I understand it, everything will immediately begin to be copied to the computer's hard drive, and then installed on removable media. So you can safely go to the kitchen and drink coffee.

If you do this slowly, then upon your return you will see a victorious message of the following type on the screen. That's all, now we can say for sure that the creation of a bootable Windows 10 flash drive went smoothly and without problems. And we made it the official way, there will be no viruses and other surprises.

After that, this USB drive was inserted into the laptop, where it is used and the operation to install the operating system went without a hitch. But I will tell you about this already in, and now let's watch an interesting video.
