Solution to the problem

If you’re using search engine friendly URLs than you may get similar error pages. This happen because of .htaccess file which has rules for mapping website URLs to posts. If any how your .htaccess file is updated by any plugin or theme and it deleted some of its part than it may cause you similar problem. you have to again update this file by writing mapping for URLs or can ask your hosting provider for re installing this file from your website backup and you will have your website working.

Windows 7 installation problem :setup was unable to create a new system partition

For answer to this error: “setup was unable to create a new system partition or …” please see this paragraph

Many of us face this problem when we try to install windows 7 on our system. Today I try to format my existing windows 7 operating system  (OS) which was working fine but I was getting some error while working on eclipse for developing  android apps. I googled for solving eclipse problem but unable to get any solution  than I thought I will move to ubuntu which was installed on my system and I use for completing  on my college assignments. When I tried to login on ubuntu I found that I forget my password. I know how to remove password without knowing it (hacking trick I will Share it later), but i preferred to clean my Laptop and install fresh OS copies of win 7 and ubuntu.

Now i got this error “setup was unable to create a new system partition or ……” when i tried to install windows 7 using Bootable USB pen drive as my CD rom was not working. I start well showing me all screens but When I tried to select hard disk partition 0, which contains previous windows 7 copy than it gave me this error “setup was unable to create a new system partition” I search on google and there were many answers like clean your hard disk using command prompt using shift +F10 key and executing some commands like diskpart and clean all etc…by using these methods I may lost my data which I don’t want. but non of them worked for me than i search more pages on installation error and I come to know that If you are having two different hard disks and these hard disks contains any other OS than  you may get this error but On my laptop I have only one disk than why I ma getting this error. Answer for this question is that pendrive is also a hard disk and it contains windows 7 which is booting my system.   what works for me is this.

Solution to this error “setup was unable to create a new system partition”

If your are using Bootable pen drive than it may cause this error so what I did after windows loads its all file I removed pen drive and than follow the other instructions on the screen. It helps me do get this screen on my laptop after fighting for 3 hours. Please comment if this method works for you.  After installation please update your windows for better security.

How to Protect Personal Computer from hackers.

How Hacker will Attack you PC?

Physical access to your PC.

If  hacker have physical access to your pc than without knowing your password he can access your  personal computer (PC).  It is very easy to access any windows PC’s. How they  break your password is simple all they use are some tools which run Brute Force attack. In this attack they try all the possible passwords and if they are lucky than they will have your secret password. They don’t do it manually but uses some software’s which are freely available on internet.

Understand the working of  your PC.

When you switch on PC it start loading your operating system (OS). There is a section on hard disk known as boot loader where address  your OS is saved after that your OS is loaded to memory (RAM ) and other processes in OS started after loading. Now you will see a screen with your user name when you enter your password here windows check it with the password stored in your system. This password is stored at following location.


SAM (Security Account Manager) file. In this file your data is stored in Hexadecimal format which is called hashes which mean your password is converted into a hash value or we can say that it is encrypted but here we can not decrypt it because it is a hash value. What your OS does is when you enter password it convert that into a hash value and compare it with hash value stored in SAM File.

What hackers Do?

They run a software to try all the possible passwords. If your password is weak(simple string of alphabets like “andhfhfka” or “adfjjdf” ) than they will crack it very quickly.

Which software’s they use for attacking  your system. Here are few names.

  • OPH Crack
  • Kon Boot
  • Offline Pwasspowd Cracker
  • Hiren Multi Boot Disk.

What is Solution

Use strong password it means your password should contain lower case, upper case at least one number, one special character (@#&*!)  and should be at least 8 character long  for example “pAssworD*8”  this will make any software too difficult to try brute force  attack on your system. Don’t allow people access your system whom you don’t know.

Back Door Entry into your System.

This attack is only possible when some one had access to your PC before and he modified some settings in your system and created a back door like using syskey feature of windows (pressing shift key 5 times).
