How To Partition Hard Drive in Windows 8.1 - Three Simple Steps


When you bought a new Laptop or PC, the hard drive may be 500GB, 1 TB or something. It may have only one partition (C: \ drive) or two drives C and D. The first thing you need to do is to make partitioning of the C drive.
Disk partitioning is essentially separating the hard disk into different sections or parts for storage. Separate partition of hard disk makes you manage your files conveniently in a more efficient way.
Note. Before doing this it is recommended to make a backup of your System Files. I used AOMEI Backupper.
There are mainly two methods to make hard disk partition in Windows 8.1, namely
Disk Management and a third-party free partition manager software. I prefer the third-party software because it is much more easier to handle and has more features.
I will explain you how to use “AOMEI Partition Assistant” a third-party software.
AOMEI Partition Assistant is a professional and advanced partition software, not only includes basic features, but also advanced features, such as Move Partition, Merge Partition, Disk Copy Wizard, etc.

Step1: Install AOMEI Partition Assistant Standard Edition in your system. 

Step2: Launch the program and right click on C drive and select Create Partition option. 
In the pop-up window, adjusting the new partition size manually by dragging the slider bar leftwards or rightwards or entering the exact size. In addition, you can enter a partition label, select partition type (Primary or Logical) and file system by clicking "Advanced>>" option.

Step3: Click "OK". You can see that Windows 8.1 hard drive has a new partition. Click "Apply" to complete the operations.

AOMEI Partition Assistant Standard  can be downloaded from the link :  http://download.cnet.com/AOMEI-Partition-Assistant-Standard-Edition/3000-18512_4-75118871.html?part=dl-&subj=dl&tag=button

Press Ctrl+Alt+Del to restart

A disk read error occured
Press Ctrl+Alt+Del to restart

Often you come across the above message when you update operating system in dual boot system: Windows 7 and Linux like Ubuntu 13.04.
Your Ubuntu is working well but cannot boot Windows 7. You can correct this problem just by modifying the grub.cfg file in Ubuntu as follows:

Note that you cannot directly modify grub.cfg file. But there is a way to do it as explained below.

First you need to check the grub.cfg file. In Ubuntu13.04, you can see this file by clicking Files/Computer/boot/grub/grub.cfg

The grub.cfg file starts with the following text.

#
# DO NOT EDIT THIS FILE
#
# It is automatically generated by grub-mkconfig using templates
# from /etc/grub.d and settings from /etc/default/grub
#
 ...........
.............

Under "### BEGIN /etc/grub.d/30_os-prober ### " you may see the insmod as ldm.
The set root was set to /ldm/(lotofhexnumbers)/volume1.
In my system, Windows 7 is installed in first partition and Ubuntu in second partition drive. 


You can edit above two lines from the root.
Go to terminal sudo gedit /boot/grub/grub.cfg. Change the two lines as given below:

insmod part_msdos

set root='(hd0,msdos1)'
 
One way to modify grub.cfg is to edit 40_custom file under etc/grub.d/40_custom
But the easiest way is to use the command sudo -w /boot/grub/grub.cfg 
 
 
Save it, reboot the system and selecting the Windows will boot normally.
