How to make bootable pen drive?

Now days use of CD/DVD has become obsolete. Prior to pen drive in existence, we had to keep the bootable CD/DVD of operating systems if we use desktop PC. Now days CD/DVD not necessarily  required to install OS on PC. You can install your desired OS by making your pen drive bootable. So to make any OS to boot from pen drive you required :-

• .ISO (Windows xp, 7, 10, Ubuntu, Fedora etc) image of operating system.
• UltraISO software (You can use trial version).
• Pen drive 

I have used UltraISO Premium Edition, version 9.6.6.3300.

Install UltraISO if it require installation and open it as "Run as administrator".

User Access Control will prompt click Yes and then Continue to try.

Now go to File ---> Open and then select your OS ISO image file from saved location.

Now go to Bootable menu then select Write Disk Image...

Now verify that in Disk Drive there should be your pen drive. In image file there should be a location of your OS ISO location path and write method should be USB HDD+. If everything is OK, click on Write button. (Note:- your all previous data of pen drive will be erased.) 

You will be asked for confirmation, click on Yes to proceed. Wait till completion of process.

Wait till full writing of image on pen drive. You will see "Burn successful " in message box.

Now safely eject your pen drive and install your OS from pen drive. Make sure that you system BIOS should be  set to boot from pen drive (USB FDD or USB HDD or Flash Drive options in BIOS).

When automatic repairs fails on boot in Windows Server 2016./How to reapair MBR (Master Boot Record).

Due to direct power off of my Windows Server 2016, it failed to boot and always stuck on automatic repair screen and advanced options.

Let see how can I overcome from this problem on my Windows Server 2016.

1. I choose command prompt, after some time I got elevated command prompt screen.

2. I typed diskpart. This command will bring diskpart tool on command prompt screen.

3. Then I typed list volume. It shows all drives and their label and drive letters (e.g. C, D, E etc). You have to identify what is the drive letter of your OS, in my case, it was C. After identifying my OS drive, I exited from diskpart.

4. To exit I typed exit.  After exiting diskpart, you will be again on command prompt.

5. After exiting from diskpart tool. Go to your OS drive from command prompt. (In my case C is my OS drive letter then I typed C: and press enter)

6. I typed bootrec /fixmbr. 

7. After successful completion of above command, I typed bootrec /fixboot.

8. After successful completion of above command, I typed chkdsk /f /r. This command asked for my confirmation in just y/n . I typed Y. This command took too much time to fix issues. But finally it was successful.

(If again problem persist, then repeat this process again and use a command bootrec /rebuildbcd before chkdsk /f /r)

After restarting my Windows Server PC, my PC was able to boot successfully and everything was as it as my previous one.

Good luck!!!
