Boot Iso From Android Bootloader

Posted on  by

The other day I decided to upgrade and rebuild my test PC. This is simply a machine I can use for installing and trying out software as well as trying slightly more adventurous things out I wouldn’t, or couldn’t do on my normal machine. Sometimes a virtual machine might do the job, but often there’s no substitute for getting the required tasks done on real hardware for the most accurate results. Some of you will probably have an old second PC or laptop and use it in a similar way.

One thing you do want when using a system that you know is going to have issues, is a complete backup of the operation system. The System Restore option or snapshot software like Comodo Time Machine might get things back running, but there’s nothing like restoring the Windows installation to a known completely clean and stable state.

Subject: Re: Booting Android from GRUB2 bootloader and Thinkpad Infos I tried something else: I installed again a read/writeable system on USB, and added a new boot entry on the bootloader in my harddisk. The GRUB2 entry to specify the first partition of the second harddisk (which is the USB stick) as root is called set root='(hd1,1)'. Boot an ISO directly from the Windows Boot Manager. Click the ‘ Add New Entry ‘ button. In the Portable/External Media window click the ISO tab. In the Name: box, enter the text to appear on the Windows boot menu 4. For the Mode: dropdown, use Load from memory if your ISO is relatively small (less than 200MB).

Bearing that in mind, I made a bootable USB stick and created some backups using EaseUs Todo Backup Workstation. Unfortunately, I put the recovery files on a slow stick and it took forever to boot into the backup software. It was then I remembered that there exists the ability to take an ISO image and get it to boot from hard drive using the Windows Vista and 7 Boot Manager. This would make booting into the recovery environment far quicker and also removes the need to use a CD or plug in a USB stick every time.

The software I used to achieve this is EasyBCD from Neosmart Technologies and it’s free for non commercial use. EasyBCD has a large amount of options for editing and creating entries for the Windows Bootloader and has helped me out quite a few times. Although the program does not come as a portable version, you can simply create your own by opening the installer and extracting it with 7zip.

There are also options to mount Virtual Hard Disk images, WinPE Ram disks, Floppy images and Raw disk / partition images. The option to be looked at here is the ISO function which will put an entry into the boot menu and then boot from the ISO you have selected. Firstly start the program, you will begin in the View settings window which shows the current entries in the Boot Manager.

As incorrectly making changes to the Boot menu could potentially cause none of your operating systems to boot, it’s a good idea to make a backup of the Bootloader settings first. Click ‘BCD Backup/Repair‘, choose a location to save the backup to and then click ‘Backup settings‘.

To create the ISO Boot Manager entry:

1. Click the ‘Add New Entry‘ button.

3. In the Name: box, enter the text to appear on the Windows boot menu

4. For the Mode: dropdown, use Load from memory if your ISO is relatively small (less than ~200MB). Select Run from Disk for anything bigger.

5. Point to the ISO file you want to boot from in the Path: box. Make sure not to move or rename the file after adding it to the menu or it obviously won’t boot.

6. Click Add Entry.

If you go back to the View settings window, the new entry should now be entered into the list. There will be a new folder called ‘NST’ created in the root of the partition where the Bootloader is located, make sure not to delete it. Close EasyBCD.

Now when you reboot your Vista or Win 7 machine the options will be visible on the Windows Boot Manager and are selectable like any other option. You may have to scroll down to see all the entries if you have entered quite a few.

IMPORTANT NOTE: Do be aware that not all ISO’s will work using this boot method and Linux distro’s are known to be a little troublesome. All the images in the above screenshot worked fine, but for example, Parted Magic did not work from Hirens Boot CD but works fine using its own standalone image. The Hiren MiniXP and the older Hiren version of RIP Linux work OK though. Kaspersky Rescue Disk 10 did not work. Although I have not tried this myself, I have heard of someone successfully mounting and installing Windows 7 using this method. It is simply a case of try it and see.

Hi All, EasyBCD’s functioning for UEFI is very limited & one would need to use something like EasyUEFI for this particular functioning !

Awesome sharing man!!! very useful @ certain times like Windows crashes or boot time bluescreen errors

For WinPE images, don’t use the boot from ISO tool in EasyBCD since it doesn’t boot correctly. Instead, extract the WinPE ISO wherever you want. Then in EasyBCD choose Add new entry > WinPE > Navigate to the folder where you extracted the ISO > Choose sourcesboot.wim. This will boot the WinPE WIM file instead of the ISO.

Hello Raymond, you mentioned Hiren’s MiniXP could be added using EasyBCD but… how??
I have tried the ISO option using the XP.BIN since there is no ISO in Hiren’s MiniXP folder but it only boots to a grub console.

hi!
firstly, thanks for this articulate article. this could be of big use for those not yet exposed in retrieving / restoring Windows installation to a known completely clean and stable state.
but i thought it was raymond himself the author and then found our it is …hal9000.
anyway, i thought this may be of help too! once, raymond himself posted about using macrium reflect, the free edition(version 4.2, build number 3141). I still use it and it’s hassle-free!

Great great tutorial and software with excellent suggestions! I have used a number of backup and disk mirror strategies in the past, but this really seems like a fine and easy method to insure a stable alternate recovery with a known OS image. I might also suggest that one might easily create an updated ISO image with your existing documents and settings, using any of several reliable ISO burning tools, such as Magic ISO or WINISO, etc.

Thanks a lot for this, I will definitely play with this strategy and duplicate for clients and friends if it proves as easy as I think it will be. :-)

U-Boot is capable of starting a complete Android system from a microSD card. To boot a system from a microSD card, follow these steps:

1. Create a bootable microSD card from an Android image

Requirements:

  • Root/Administrator permissions in your development computer
  • A microSD card with a minimum capacity of 2 GB

The following procedure will destroy existing data in the microSD card.

To create a bootable microSD card from an existing Android image:

Boot Iso From Android Bootloader Download

  1. Download the bootable Android image from this URL: ftp://ftp1.digi.com/support/android/5.1.1/r4/images/82003938_C/ccimx6sbc/eng/sdcard.img.gz
  2. Extract the .sdcard file from the zip you downloaded into a folder of your choice.
  3. Raw write the image on the microSD card using one of the following methods:
  1. Insert the microSD card into your computer and check the node Linux assigns to it (/dev/[sdcard]) using dmesg:

    CAUTION! Using an incorrect device node in the next step might destroy all data on your computer hard drive.

  2. Raw write the image file to the microSD card with this command:

    where:

    • <path/filename.sdcard> must be substituted with the path and filename to the SD card image.
    • <sdcard> must be substituted with the device node assigned by Linux to your microSD card.

The microSD card is now ready.

  1. Download the Win32DiskImager software from http://sourceforge.net/projects/win32diskimager/files/latest/download.
  2. Uncompress the software and run it as Administrator.
  3. Insert the microSD card into your computer.
  4. In the software, select the drive that corresponds to the microSD card. Select the .sdcard image file you want to program and click the Write button.

The microSD card is now ready.

2. Boot Android from the microSD card

Bootloader Android Download

  1. Power off the device.
  2. Insert the microSD card into the microSD card holder (bottom side of the board).
  3. Change the boot mode configuration to boot from the microSD card. To do so, set the boot mode micro-switches as follows:
    • SW3.1 OFF
    • SW3.2 ON
  4. Power up the board.

Android now boots from the microSD card.
