Booting from iso images using memdisk and grub4dos

  1. OPENING ISO IMAGES USING STANDARD WINDOWS TOOLS (ONLY WIN 8 AND HIGHER)
  2. OPENING ISO IMAGES USING SPECIAL PROGRAMS
  3. OPENING ISO IMAGES USING ARCHIVERS

Quite often on the Internet you can find files with the extension “.ISO”, which are disk images.
Typically these are games or distributions of various operating systems, including Windows. Programs are often distributed in ISO format. The ISO image itself cannot be installed, because it is not an executable file. However, it can be opened and/or unpacked. If the ISO image contains, for example, a game, then after gaining access to the contents of the ISO, it can be installed in the standard way.

PassFab for ISO

If you ever need such help, you must find an effective program that can perform the said task. We prefer to use PassFab for ISO in such scenarios as we find it to be the most efficient and easy to use. So, without wasting any more time. Let's look at the procedure to burn ISO file to USB using software:

This is the most efficient way to burn ISO image to USB.

OPENING ISO IMAGES USING ARCHIVERS

In a way, ISO images are archives, so they can be opened (opened, not mounted as a virtual drive) using an archiver that supports these file formats. Among free archivers, one of the best options is 7-Zip :

  • Download and install the program.
  • Go to the folder with the ISO file and double-click on it with the mouse or call up the context menu above it, select the “Open with” submenu and then “7-Zip File Manager”.

  • In the window that opens, you can see the contents of the ISO file. Click the “Extract” button at the top of the window, then in the “Copy” window, specify the folder to extract the ISO image and click “OK”.

  • Once unpacking is complete, go to the specified folder, from where you can begin installing the game or program.

WinCDEmu

If you are looking for an open source ISO mounter, then you need WinCDEmu. The software will be integrated into Windows Explorer after installing the software and you can launch it simply from the context menu.

The operation is very simple, the ISO file can be mounted with one click. You will also be able to mount different types of ISO files. The list includes CUE, CCD, NRG, MDS/MDF and IMG files. The program will allow you to create several virtual disks, but other than that the options are very limited. But it will handle your basic needs.

Completing Grub setup

We have everything prepared, now all that remains is to update the Grub bootloader configuration so that new items are added to /boot/grub/grub.cfg and appear in the boot menu. For Ubuntu the command will look like this:

sudo update-grub

On other distributions you may need the command:

sudo grub-mkconfig -o /boot/grub/grub.cfg

Then you can reboot and see what happened:

If something goes wrong, you can press the E and edit this menu item to try to fix the problem directly in the bootloader.

Microsoft Virtual CD-ROM

Booting a computer from a USB flash drive or other removable media

In order for your computer to start from a CD, DVD, flash drive or external USB drive when rebooted or turned on, you need to make changes to the BIOS settings. Most modern motherboards provide the ability to boot from a USB flash drive , but on older models you can sometimes only enable boot from optical drives. This problem in some cases can be solved by installing the latest BIOS version, but for very old motherboards such updates may not be released.

After turning on the PC, go to the BIOS by pressing the “Del” or “F2” key. Then find the appropriate menu items, indicating the boot order and devices used for this. Depending on the manufacturer and BIOS version, this can be done in the “Boot” or “Advanced BIOS features” sections. In addition, modern motherboards allow you to specify the device from which the system will boot without reconfiguring the BIOS. To do this, when starting the PC, you need to call the “boot menu”. As a rule, this can be done using the “F12” key.

Checking the bootable flash drive is necessary to make sure that the bootable flash drive is working and can boot from it on the computer. After writing an ISO image or files to a flash drive, it makes sense to check whether the flash drive is bootable.

Bootable media are USB flash drives, CD/DVD disks, ISO images from which you can boot when you turn on or when you restart the computer. If you select boot priority from removable media in the boot menu or BIOS, the computer will start booting from the boot disk.

The user should take care of creating bootable media in advance in order to be prepared for surprises, which, as a rule, happen at the most inopportune moment.

Basically, a bootable flash drive is used when force majeure occurs. Possible reasons why you may need to use a bootable USB flash drive:

  • there is a problem with the system, the Windows operating system cannot boot, to restore the system you will need to boot from a bootable USB flash drive or from an emergency recovery disk;
  • due to virus infection, it is impossible to launch an anti-virus scanner from Windows; for treatment, you must use an emergency boot disk from the anti-virus manufacturer;
  • there was a need to reinstall the Windows operating system;
  • After a serious failure, you need to restore or copy files from your computer disk.

Therefore, it is worth having bootable disks with you to be prepared for all surprises. Boot disks are created using a large number of programs. If the flash drive is not bootable, booting the computer from the USB flash drive will become impossible. Because of this, the user will not be able to solve the problems that arise.

How to check that a bootable USB flash drive is working? There are several ways to check a bootable USB flash drive:

  • checking the bootable USB flash drive when loading directly on the computer;
  • checking a bootable USB flash drive on a virtual machine emulator without rebooting.

In the first case, it is clear that you need to boot from the flash drive and check its operation. In the second case, programs for checking a bootable flash drive will help.

The applications are add-ons to the QEMU virtual machine, which allows you to check the ability to boot from a flash drive or from an ISO image without rebooting the computer.

Using programs, you can find out whether the flash drive is bootable, check the ability to boot from an ISO image or USB drive on your computer. The user will be able to make sure in advance that this flash drive or image will boot on the computer.

The programs presented in the article (MobaLiveCD, Qemu Simple Boot) are various shells of the QEMU emulator, others connect this emulator for testing (WinSetupFomUSB), or are an add-on to the VMware Workstation Player program (VMWare WinPE Test). MobaLiveCD and Qemu Simple Boot check ISO images and flash drives, WinSetupFomUSB checks bootable flash drives, and VMWarePETest checks bootable ISO images.

Pismo File Mount

Burning an ISO image to a USB flash drive

Method number 1 - PowerISO

PowerISO is a very powerful program for working with ISO images. Allows you to open them, edit them, extract files from them, add files to ISO images, compress them, burn them to CD/DVD disks and flash drives, etc. Also in PowerISO you can make an image of any of your disks, test it, get a checksum (to assess whether the file is broken.).

In general, how to write an image to a flash drive using PowerISO.

1) The first thing you do is open the image. To do this, click the "Open" button, or open the file menu, and then specify the image file. You can also use the Ctrl+O keystroke.

PowerISO - opening an ISO disk image

2) If the image was opened and the program did not issue any warnings, go to the “Tools” menu. Select a function such as “Create a bootable USB drive” (see the arrows in the screenshot below).

Create a bootable USB drive

3) In some cases, the program will ask you to give it administrator rights. We just agree: the program will restart and you will continue the recording process.

With administrator rights

4) In the recording settings window, you need to:

  1. In the “USB drive” column, indicate your flash drive (Caution! Do not mix up the letters, because during the recording process, all data on the flash drive will be deleted;
  2. recording method: if you are recording a bootable ISO image, select the “USB - HDD” recording method (for example, to record images from Windows);
  3. the file system column can be left as default;
  4. then click “Start”;
  5. By the way, please note that at the bottom of the window there are links to instructions (several links, depending on the image being recorded).

Burning settings in PowerISO

5) The program will warn you again that all data on the selected flash drive will be deleted!

Warning: the flash drive will be erased

6) Next, the recording process will begin. Recording time depends greatly on:

  1. loading your computer with extraneous tasks (I recommend turning off everything unnecessary: ​​at least torrents, games, video editors, and other programs that put a lot of stress on the PC);
  2. size of the recorded image;
  3. speed of the USB drive and the flash drive itself.

7) If the recording went well and without errors: you will see the message “USB drive recording completed successfully”, as in the screenshot below.

Successful burning of a flash drive

Method number 2 - UltraISO

UltraISO is the most famous program for working with ISO images. It can do almost everything with them like the first one: open, mount, edit and modify, burn bootable flash drives, external hard drives, CD/DVD drives, etc.

It is as easy to use as the first one. Both, by the way, fully support the Russian language.

And so, let's start working in UltraISO

1) First, download (link above), install and run the program. There is nothing special to comment here, except for one thing - run the program as an administrator (otherwise the option to write a USB flash drive may not be available!).

Note! To run as administrator: just click on the UltraISO program icon and select “Run as administrator” in the context menu, as shown in the screenshot below.

Run with administrator rights

2) Next, open the ISO image file (to do this, click the menu “File/open”).

UltraISO - opening an image

3) If the image has opened, open the menu “Boot/Burn disk image” (see screenshot below).

Burning a disk image

4) Then you need to set the recording settings:

  1. disk drive: select the letter of your flash drive (the data on it will be deleted, so be careful and attentive!)
  2. recording method: either USB-HDD+ or USB-HDD (this is for recording bootable media, which is what is required in most cases). It’s quite difficult to say specifically what to choose; in most cases, USB-HDD+ works - but if suddenly your BIOS version does not see it, rewrite the flash drive in USB-HDD mode;
  3. then click the “Record” button.

UltraISO recording settings

Note! In normal mode, UltraISO automatically formats the media into the FAT32 file system (even if the flash drive was previously NTFS). In order for NTFS to remain, you need to select ExpressBoot, then click on ExpressWrite. Bottom line: when you unpack the image onto a flash drive, the file system will remain unchanged.

5) Next, a standard warning will appear about deleting all information from your flash drive. We check the letter of the flash drive again and agree.

Deletion Warning

6) If everything went well, you will see the following message in the program message: “Cache synchronization. Recording complete!” . Please make sure that there are no errors in the list of program messages, otherwise your boot image will simply give an error when installing Windows
