RMPrepUSB - Boot ISO files from a USB flash pen drive - Videos

This is a continuation of my Original Post... What can RMPrepUSB do - RMPrepUSB - grub4dos, .iso images and Booting from USB? There is so much great info on this Site, that I have just scratched the Surface!:) Make sure and go to the links for the Complete info...


RMPrepUSB is a Windows utility that allows you to quickly format your USB drives (or non-USB drives) and install different Operating System bootloaders onto it for XP, Vista/Win7/Win8, MSDOS, FreeDOS, Syslinux or grub4dos at the click of a button. This allows you to 'roll your own' bootable USB drives. RMPrepUSB has hotkeys that speed up this process (press F1 to see these). Most of the Tutorials on this site use the grub4dos bootloader. The grub4dos bootloader enables you to create a user menu which can contain a variety of entries. For instance, if you follow some of the tutorials on this site you can create a USB drive that will boot on most systems and allow you to: install XP onto a system, install Vista onto a system, install Windows 7 onto a system, install Server 2008 onto a system, repair an OS, boot to MD-DOS, boot to FreeDOS, flash a new BIOS, run a memory test, run a hard disk scan test, boot to a number of different linux operating systems, wipe a hard disk, reset or recover Windows user passwords, clone a hard drive, boot to BackTrack to check WiFI security, recover files/pictures from a corrupt Flash memory card and much more.

  1. Install RMPrepUSB onto your Windows computer
  2. Copy RMPrepUSB to another disk so that you can run RMPrepUSB from any Windows system (i.e. portable)
  3. Wipe, Partition and Format a USB drive
  4. Make a USB drive that will boot to DOS (for instance to flash a new BIOS onto a computer)
  5. Backup an image of a USB drive and then restore it to a different USB drive
  6. Check to see if a USB Flash memory drive is good or fake (e.g. eBay / 'bargain' purchase)
  7. Check the read and write speed of your USB drive
  8. Introduction to making a multi-boot USB drive (e.g. have one flash drive that can install Windows 7, Server 2008, run Hirens Boot CD, wipe CMOS, wipe hard disks, boot to linux, run backtrack 4, boot to WinPE to image hard disks, etc.)

PART 3 - Adding the UBCD4WIN ISO file to your favourite grub4dos multi-boot USB drive

Let us assume that you already have a grub4dos multiboot USB drive which already has some bootable ISOs on it. There are several ways in which you can add UBCD4WIN to this drive. The first way is to simply copy the files from your USB drive made in PART 2 of this tutorial to your USB multiboot drive. Then add an entry into your menu.lst as follows:

title UBCD4WIN
find --set-root /ntldr
chainloader /ntldr
root ()

Note: you could also chainload from /MININT/SETUPLDR.BIN instead of NTLDR.

However, you may already have XP or BartPE files on your USB drive or you may just want to boot from an ISO file. This can be done as follows:

  1. Download firadisk.gz from the Beta Downloads Tutorial section of this website.
  2. Copy firadisk.gz to your multiboot USB drive.
  3. Copy the iso file from C:\UBCD4WIN\UBCD4WinBuilder.iso to your USB multiboot drive.
  4. Add the following menu item to your existing menu.lst file:

    title UBCD4WIN from ISO file using firadisk
    find --set-root --ignore-floppies --ignore-cd /UBCD4WinBuilder.iso
    map --mem /firadisk.gz (fd0)
    map --mem /UBCD4WinBuilder.iso (0xff)
    map --hook
    root (0xff)
    chainloader (0xff)

  5. Now go try it!

You can use the same technique with any XP/BartPE based ISO image.

Tip: You can compress the iso file using 7zip to a GZip file (.gz extension). This achieves an almost 50% reduction in size and so takes up less space on your USB drive (you could then use a 512MB USB flash drive). Just copy over the compressed file /UBCD4WinBuilder.iso.gz in place of /UBCD4WinBuilder.iso and change the menu.lst entries.

Note: Regardless of if you use an .iso file or a .gz file, because the whole contents of the iso file is loaded into and runs from memory (RAM); you will still need a system with 1GB of memory (or more) and the amount of free memory once UBCD4Win has booted will be reduced by the same size as the files (i.e. 600+MB of files), so on a 1GB RAM system you may only have 200MB of RAM once UBCD4Win has booted.


You can download the binary application as an ISO file or as pre-compiled binary. However, to use the pre-compiled binary you will need to use the kernel command in grub4dos but on some PCs, this option does not work because the kernel command loads the binary file into an area of memory which is limited in size and so you will receive an 'error 28: selected item cannot fit into memory' message. 
To avoid this issue, the following method is recommended:
  1. Download the Pre-compiled bootable file from here 
  2. Use 7Zip or any other utility to open the ISO and extract the file memtest.img from the \boot folder
  3. Copy the memtest.img file to your USB drive
  4. Create using Notepad the file menu.lst on your USB drive and add the following lines:

    title memtest86+ v4.10
    find --set-root /memtest.img
    map /memtest.img (fd0)
    map --hook
    chainloader (fd0)+1
    rootnoverify (fd0)
    map --floppies=1

    The drive is now ready to test.

Part 1 - Make a bootable USB pen drive

  1. Download and install RMPrepUSB onto your Windows XP/Vista/Win7 system  (always use latest Beta) .

  2. Insert a USB Flash memory pen drive (or USB hard disk) into the USB port of your Windows computer and run RMPrepUSB - set the following options:

    1. MAX size
    2. MEMTEST  as a label
    3. MS-DOS
    4. FAT16 (or use FAT32 if you have >2GB USB drive) + Boot as HDD (2PTNS)
    5. Leave COPY FILES box unticked
    6. Click Prepare Drive to format the USB pen (Note: you will lose all contents as it reformats the drive!)

    Fig. 1 Notice that the settings are numbered 1 to 6 for you - just set each one and then click on 6 Prepare Drive

  3. Click on Install grub4dos - answer 'Yes' to use the MBR option and hit Enter when prompted to copy the grldr file over - or use PBR option if you prefer.
    (You can use MBR or PBR with RMPrepUSB as it uses a special version of grubinst which works even when booting MS-DOS)

  4. Now follow tutorial #20 on how to add MemTest86+ to the USB drive you have just prepared (Memtest86+ is a good one to start with because it is quick to boot and ideal for testing the grub4dos menu with - or if you prefer, try tutorial #37 for a FreeDOS USB bootable pen drive).

    Assuming you have added MemTest86+, you should now have a USB drive with the following 3 files on it:


    Note that grub4dos consists of two parts as explained previously. Part 1 is the boot code which does not actually exist as a file and so cannot be seen. It's code can be located either in the Master Boot Record (first sectors on a disk) or in the Partition Boot Record (first sectors at the start of a partition). This is written to the disk when you click on the 'Install grub4dos' button. Part 2 is the main grub4dos code which is loaded by the Part 1 boot code. Part 2 is just the file grldr which should be located on the root of your bootable drive or boot partition. This grldr file is also copied from the RMPrepUSB application folder to the drive when you click on the 'Install grub4dos' button. If you wish to use a different version of grub4dos, simply replace the grldr file on the USB boot drive with your different version.

    Once glrdr loads, it will look for a menu to display. The menu is in the form of a file named menu.lst which is normally placed in the root of the drive. If one is not found, grub4dos will display a command prompt. You can type in grub4dos commands at the grub4dos command prompt (such as help).
Here is a video on how to make a menu.lst menu file and it explains some of the command words that can be used in the menu.
