A request before solving it:
This is very easy assignment which requires only the implementation of a given scenario. This implementation will build your understanding of real mode and protected mode limitations more clearly. So, do not paste your solution from any kind of source. Just do and describe the solution in steps if possible. Otherwise describes the reasons of No answer shortly.
Question: Marks 20
Ahwas installed 64 bit operating system on his PC. Unfortunately, his system crashed and could not boot even in the safe mode. He has two equal partitions of his 120 GB hard drive. He has an important data on his secondary partition. He has a DOS bootable USB drive with FAT16 structure. Is it possible for Ahwas to access his important DATA from hard drive and copy to USB drive through available DOS bootable drive? Give logical reason for your answer.
Note: Google the different possibilities for the given scenario assuming that it happen with you. Implement all founded possibilities on your system then suggest a feasible solution for Ahwas within steps. You also can use any other utility within the scenario limitations.

There are following steps for booting a system.
Plug in the flash drive. Make sure that it is plugged into the computer itself and not through a USB hub.
Turn on the computer. Every computer manufacturer has a different boot screen. As soon as you see the logo, you will need to hit either F2, F10, or Del to enter the BIOS menu. These are the most common keys for entering the BIOS menu. The key you need to press will be displayed under the logo.
Find the Boot menu. If you hit the correct key at the correct time, you should now be in the BIOS menu for the computer. This is where basic computer functions are set, before an OS (Operating System) is loaded. Navigate to the Boot menu. Every manufacturer has a different BIOS setup. Some have the menu in a column; others have tabs across the top. Here’s an example BIOS:
Change the boot order. Once you are in the Boot menu, you will see a list of devices. This is the order of devices that the computer will attempt to find an OS on. Typically, the first device listed is the computer’s hard drive, usually followed by the CD/DVD drive.
Save and exit. Navigate to the Exit menu in the BIOS. Select “Exit and Save Changes.” Alternatively, many BIOS have a shortcut key displayed at the bottom that will save and exit with one keystroke.
Wait for your flash drive to load automatically after the reboot. After a few seconds, depending on what your flash drive is made for, you will be given control. If you made an MS-DOS flash drive, you will be given a command prompt after booting.
Use this command
xcopy e:\source_folder f:\destination_folder /e /i /h
The /h is just in case there are hidden files. The /i creates a destination folder if there are multiple source files.
Connect your secondary drive.
Connect the data cable. Find the wide cable that the hard drive in the computer case is connected to. There should be a long plastic connector plug somewhere in the middle this cable.
Add power. Find a power connector that is not hooked into anything. It will usually be black or white, with 4 female sockets.
Put it back together. Plug the power, monitor, keyboard, mouse, and anything else you unplugged back into your computer.
Turn on the computer. Everything should boot normally at this point. If not, power down and check all connections.
Drag and drop the files from your main hard drive to the new hard drive.
Determine what type of hard drive you have. There are many interface variations, IDE, SATA, PATA, and more.
Purchase an external USB housing. Make sure that it is suitable for your hard drive. This example features an IDE drive.
Open the external drive case. Plug in the drive power and data leads. Note: these are keyed so that you can only put them in one way—the correct way! If you need to force it, you are probably wrong.
Power up! Make all your connections secure and then power your system back up.
Wait for your system to find the USB device. If using Microsoft Windows, check in My Computer.
If using SuSE Linux: Check My Computer if you don't get a screen pop up with the device listed.
Copy the data to the external second drive

otherwise we all know it is possible to copy data from hard drive to usb
