How to install Windows® 7 from Hard Drive?
Have you ever thought about installing Windows 7 without using any DVD or USB drive? Yes hard to believe but still possible. People who don’t want to burn the Windows 7 ISO image to a DVD or those who don’t have a windows installation disc can now install Windows 7 on their systems.
Installing Windows from the Hard Drive is quite faster than installing from DVD/CD. This article has been written on the assumption that the new Windows 7 is going to be installed and replace the current OS.
Follow the given instructions to perform this task:
STEP 1. On your current Operating System install a virtual DVD/CD drive first. Magic Disc virtual DVD/CD ROM can do this and is free.
STEP 2. Now mount the ISO image of Windows 7.
STEP 3. Then copy all the files from this Virtual drive you mounted now to a drive in which you don’t want to install Windows. For instance, if you want to install Windows on C drive copy them to E:\Windows7 or any other.
STEP 4. Next, copy the bootfolders and bootmgr seen inside the copied folder (here E:\windows7) to your main booting drive probably C:\.
STEP 5. Copy E:\Windows7\boot\boot.sdi and bootsect.exe from E:\Windows7\boot\ folder to C:\boot folder and C:\ drive respectively.
STEP 6. The boot folder is hidden by default tick the option to show hidden files and folder and also show protected system files from Folder Options.
STEP 7. Now under C:\ root folder create a new folder named sources.
STEP 8. Copy the boot.wim file from E:\Windows7\sources to the sources folder created in the above step (7).
STEP 9. Now right click the Command Prompt in the start menu and select Run as Administrator.
STEP 10. Now change the name of the boot system partition to any name you prefer (in command prompt use label command). for instance, type C:\ label mycdrive. Remember the name you have given.
STEP 11. Now reboot the System.
STEP 12. After that Windows will automatically run the setup process. On continuing with the installation steps when you see the option to Install Windows do not click it instead click the option to Repair my Computer.
STEP 13. Now in the WinRE System Recovery Options window open the Command Prompt.
STEP 14. Now type the following command format c: /q .
STEP 15. /q switch is used to do a quick format option it is optional.
STEP 16. If you want to convert the drive to NTFS system type the command as c: /q /fs:ntfs.
STEP 17. Just before the formatting begins, you may be prompted to enter the name of the partition as mycdrive enter it accordingly.
STEP 18. After the formatting completes Start the Windows setup from the copied folder for example, E:\Windows7\sources\setup.exe.
STEP 19. Now, follow the instructions as usual.
