1. Open an elevated Windows command line window by clicking Start, typing in cmd in the search text field, then pressing CTRL + Shift + Enter on your keyboard (at the same time). You can also access this by navigating to Start, All Programs, Accessories, right-click with your mouse on the Command Prompt menu item and select Run as Administrator.

2. At the command prompt, type cd c:windowssystem32 to change the directory to the Windows system32 directory. Ensure your USB drive is plugged in, typeDISKPART, then press Enter. Type LIST DISK and press Enter.

3. You will see a listing of the disk drives connected to your computer. Find the disk number of your USB drive and type SELECT DISK [USB disk #], where "[USB disk #]" is the disk # for your USB drive. It should now state that your USB drive is the selected disk. If youre not sure what disk is the USB disk, eject the USB drive, perform step number 2 again, connect the USB drive again, and compare the results. Usually the USB drive will be the last drive.

4. Type in the following commands, one by one, pressing Enter after each command.

5. You will now need your Windows Vista or 7 Installation DVD. Put the DVD in your computers DVD drive. Open up My Computer and note which drive letter is assigned to your DVD Drive and your USB flash drive.

6. Go back to the command prompt window and type in D: CD BOOT (substitute your DVD drive letter for "D:", if necessary) and press Enter. Type CD BOOT again and press Enter. Lastly, type BOOTSECT.EXE /NT60 H: (substitute your USB flash drive letter for "H:", if necessary) and press Enter.

7. The last step is to copy the entire contents of the Windows DVD to your USB flash drive. To do this, in the My Computer window (opened in step 5 above), right-click on the DVD drive and select Open to view the contents of the DVD. Copy all the files and folders on the DVD to the USB flash drive.

1. Install PE Builder on your computer. For the sake of ease, install the program to aC:PEBuilder folder. After youve installed PE Builder, create a folder titled SRSP1 in the PEBuilder folder.

2. Now you need to extract two files from Windows Server 2003 SP1. The filename is quite long, so it is recommended that you rename the file to something shorter, likeWS-SP1.exe. Open a command prompt (Start > Run, type cmd and press Enter) and use the cd command to change to the folder where you downloaded the Windows Server 2003 SP1 file to (i.e. cd c:downloads to change to the c:downloads folder). Then, type WS-SP1.exe -x to extract the files. A window should open asking where to extract the files. You can enter the same folder where the file was downloaded.

3. A new folder titled i386 will be created by the extraction process. Type cd i386 to change to that folder. You now need to copy the setupldr.bin file to the SRSP1 folder you created in the PE Builder folder. Type copy setupldr.bin c:PEBuilderSRSP1 to copy the file.

4. You also need to expand the ramdisk.sys file to the SRSP1 folder.

Type expand -r ramdisk.sy_ c:PEBuilderSRSP1

5. Open My Computer and navigate to the c:PEBuilderSRSP1 folder and verify the two files are there.

6. Next, you need to create a compressed version of Windows XP using PE Builder. Make sure the Windows XP Professional CD is in your computers CD drive, then launch the PE Builder program. In the Source field, type in the drive letter assigned to your CD Drive (you can check in My Computer if you are not sure) (e.g. "d:"). In the Output field, type BartPE. Make sure the None option is selected in the Media output section. Then click the Build button.

7. Now, you can create the bootable USB flash drive. Open a command prompt again and type cd c:PEBuilder to change to the PEBuilder folder. Make sure your USB drive is plugged in to your computer and type pe2usb -f e: (change "e:" to the drive letter assigned to your USB flash drive, if necessary) to create the bootable drive. When prompted to begin the process, type YES. When the process is complete, press any key to exit the program.
