In this post I am going to write about making a usb drive bootable for installing different operating systems from it. This will be helpful in case your system doesn’t have working cd/dvd drives. But before trying this method please ensure that your system supports booting from usb. Some old systems doesn’t have this option. Also check your bios to ensure that the boo from usb option is enabled. Read more…
It been long since I added an article on to this blog entirely by writing which is not based on how to. Anyway here it is and I hope it will be worth reading for you guys.
Data Recovery, is a big issue if your hard disk has sensitive informations. Like the saying its, prevention better than cure. Here you better prevent the data loss by making sure of a updated backup for the original data. so that even i fyou loose the original data you will have the copy.
You can do this back up in several ways:
1. Using Applications such as
- Norton ghost
- Sync Back
- Acronis True image
2. Using RAID
For normal home usage first option is better. So you just have to install an application in your system and do as the manual says. Raid needs higher knowledge about computer and requires some configuration changes in hardwares.
Data Recovery(not the worst case):
If you deleted some files and removed them recycle bin also accidentally, it would be very easy to recover if you just stop using the computer. If you use the computer for a long time after the deletion, it will be very difficult to recover the data. Now The best option is boot into a live cd of either windows, linux, or any custom recovery solution. In that case the recovery wil be very easier and less time consuming.
In windows, you can use lots of applications like recuvva, ontrack easy recovery professional, etc. In this Recuvva is free and the options are very limited. Ontrack is a very professional one but you will have to pay for that application. Like this you will get lots of applications for recovering the data. One thing you have to make sure is, use a external hard disk to save the data. Do not use the same device on which the data recovery is being performed.
Now in linux also there are lots of similar tools. But if you are into linux, it better you ask the support forum for the recommended recovery application. Include the reason, and what kind of files you are trying to recover.
Data Recovery(Worst Case Scenario):
Now if your HardDisk failed and you didn’t have any backups also, then you need to try other options to get the data.
First of all let me point out something in bold and underlined.
If you don’t know what you are doing, you could lose all the data, which would have been recoverable if you didn’t try anything but give it to a professional.
You can find lots of professionals for these by a simple google search. Data recovery is a highly competitive field and there are lots of good companies which give you optimal result. But the prizes will not be cheap. For good services you will have to give good amount of money. But most of the data recovery professionals give you a free consultation. Now by this you will come to know the gravity of the situation.
So only try these kind of things, once you are sure about what you are doing.
My favorite tool is testdisk. Google search it and you will find the package to install. But you will have to try it from linux, ubuntu recommended.
TestDisk have 100s of options and configuration set ups. It will be impractical to list them all. The best part of test disk is, this application will try to find and list the previous partitions and volumes. And if you found that to be correct you can just, try to recover it.
This Wiki Community Page from ubuntu will help if you chose to try this with ubuntu. But before trying you must read through it once or twice, and clear all your doubts before starting.
even if you lost the partition from windows, do try these kind of recovery stuffs from linux only. I recommend it because the options and file system support is more in linux than in windows.
It may seem too easy for some guys. You may even think, why should I even bother making a tutorial for this, I know, But we all were beginners at once, people who don’t know what to do or how to do. This tutorial is for all those people, who find it difficult or don’t know how to do it!
This Tutorial Explains how to install ubuntu 11.04 onto your computer. All your data and pre installed Operating Systems are safe with this method!
Resolution Changer For Windows Operating Systems:

Previously I have posted about “How to boot and install win xp from a usb drive”. Now I think its time to post about the win 7 installation. So now I am posting about how to install windows 7 from a USB drive, in a much simpler way.
While searching in internet I found 3 ways of doing this thing. I will explain all of them here.
1st Method: (The simple one)
* Requires a valid ISO image.
Download Microsoft’s official tool to install Windows 7 from your USB stick.
From CNET: http://download.cnet.com/Windows-7-U…?tag=mncol;pop
MS Store: http://images2.store.microsoft.com/p…B-DVD-tool.exe – Microsoft Store Info Here.
To install the Windows 7 USB/DVD Download tool:
- Click to open the Windows 7 USB/DVD Download tool installation file.
- When you are prompted to either save the file to disk or run it, choose Run.
- Follow the steps in the setup dialogs. You’ll have the option to specify where to install the Windows 7 USB/DVD Download Tool.
Note: You need to be an administrator on the computer you are installing the Windows 7 USB/DVD Download tool on. The tool requires the Microsoft .NET Framework version 2.0 or higher.
2nd Method: (Reliable method, Supports multiple types of image files)
- USB Flash Drive (4GB minimum)
- Windows 7 Image file
- UNetbootin ( download it from here).
Now insert the USB drive, run UNetbootin, and select Disk Image as ISO( or select the type of image file of which you have).
Browse your local drive for Windows 7 that you downloaded and click Open.
Now Select Type as USB and choose the drive.Once done, it will look like a bit similar to the screenshot shown below.
Click OK and it will begin extracting all installation files to the USB drive. The whole process will take some time(10-15 minutes), so have patience.
Once the installation is complete, reboot your computer. Now while your system is starting up press the appropriate button(usually F1, F2, F12, ESC, Backspace, or Escape) to bring up Bios Boot Menu. Change the startup order to boot USB by default, usually you will have to press F6 to move the selected USB device on top. Once done, save changes and restart the system.
3rd Method:( Try this if both above methods are not working)
Using Ultra ISO application.
1) Download the free UltraISO trial by clicking on this
2) Start UltraISO as administrator
3) “Burn” the iso image to the USB stick by following these steps
- Open the image of Vista/Win7 with UltraISO
- Under BOOTABLE tab choose WRITE DISK IMAGE
- Choose your USB stick under “Disk Drive“
- Choose a method (It’s recommended to use USB-HDD+)
- Press Write
PS: Make sure to change your BOOT order in BIOS to boot from your USB drive first.
