How to Format a PC and install windows 10

If you want to install Windows to your PC, you have to follow several steps. 

STEP 1:  Make your pen drive to a bootable device. 
      
           In this step, you can use a CD, which is already booted with Windows 10. Otherwise, you have to make your pen drive to a bootable device. For this, you may use a software such as Rufus, WinToBootic, RMPrepUSB etc. Here I use Rufus 2.6 version.
      

First, it asks user to select the device which you want to boot. You can select the pen drive for this.

Then it asks the partition scheme and system type. Here you have to be careful. Because if you select wrong partition scheme, you will not be able to install the OS.

According to the requirement of the user, there are two types.

    1. You want to fully format your PC.
    2. You want to format only the C drive.

              1. If you want to fully format your PC I recommended you to select the 'GPT partition scheme for UEFI'. Because it is much faster than the MBR partition scheme. But if your PC is compatible with MBR partition scheme, it may use that option. 

(You can change your partition scheme from  MBR to GPT or from GPT to MBR using 'DISKPART' option in an administrator command prompt. But it must be done in real time in real place. Otherwise, it will erase your all files.) 

              2. If you want to format only the C drive, first you have to check what partition scheme your hard disk is. For this, you can use AOMEI Partition Assistant software. 

OK.. then it asks the cluster size. The default size is not a problem. Therefore you do not need to change it. 

You can give any name for the device you want. It is up to you.

STEP 2:

Finally, you have to browse the location of the ISO image. After selecting that you can start it.  After finishing the boot process, insert the installation media into appropriate location and reboot the machine. When the PC start from the beginning you have to press some function key (It may vary according to the PC brands. Commonly it may be ESC,f2,f9,f12) 

Then a new window will come up with three or four options. One is your previous OS boot option. And there are two options will come up with your company name of your pen drive. One of this option must be compatible with UEFI. Select this and press Enter. 

STEP 3:
   

After that, your PC will pop up with Windows setup. If you are OK with language, time and the keyboard type, press Next. 

Then you can see two options in this window.
           
                     1. Install now
                     2. Repair your computer.

As I said before if you want to fully format your PC and convert the file system to specific scheme, this is the time to do it. If you want only format the C drive, DO NOT follow STEP 4. Because this will fully clean up your hard disk.

STEP 4:

                      1. Press Repair your computer.
                      2. Select Troubleshoot option from the pop-up window.

                    3. Then select 'Advanced Option'

                  4. Then select 'Command Prompt'. 

               5. You can see that this is administrator command prompt. Then type 'DISKPART' and press Enter.

               6. Then type 'list disk'. Then it will show two disks. Disk 0 is your hard drive. Disk 1 is your pen drive.

                7. Type 'select disk 0' to select the hard drive. 

                8. Type 'clean'. It will erase your data on your hard disk and that data cannot be recovered.

                9. If you want to convert your file system to MBR, type 'convert mbr'. Otherwise, type 'convert gpt'. 

              10. Then type 'exit' twice and restart your PC again. 

STEP 5:

      Yes, That is it. Now you can press 'install now'. Then below window will pop up. If you have the product key, you can type it in the dialog box and press 'Next'.

If you don't have a product key, press 'I don't have a product key'. 

STEP 6:
     
    Then another window will pop up and asks the type of installation. You can use Custom installation option. 

STEP 7:

      Now, this is the time to select your partition to install windows. If you format only the C drive,  follow these steps.
     
         1. Click on the C drive icon.
         2. Click 'Format'.
         3. Then click 'New' and press 'Apply' button. If you want to change the partition size, you can change it now.
         4. Press 'Next' to install windows.
     

If you want to fully format the hard drive, follow these steps.

       1. Click on the Drive and format it. 
       2. The click 'New' and make a new partition according to your requirement. 
       3. Then press one of the partition and press 'Next'.

This will take some time to install windows. Now you are almost done. Then the PC will restart and boot Windows 10.

STEP 8:
     

   Now you have to install drivers for your PC. So right click on windows button and select 'Device Manager'. You can select any drive and update it very easily. 

You may use the official website of the particular category of the PC too.
