Microsoft Virtual PC 2007

Ever imagined that you could run one Operating System in another Operating System and that too FREE ???

Yes!! it is true....
You could be running XP in Vista or Windows 7 in XP.....

This is not only fun but sometimes useful too,

1. Say you are running Vista and had like to run an application that is not supported by Vista,what you'd do?? One easy way is to run that application in XP,where this XP is running in Vista using Microsoft Virtual PC 2007

2. It is not easy to install multiple Operating Systems to a HDD.With the Virtual PC 2007 software you can do so easily by switching between OSs like applications with only few mouse clicks.

Easy WORD to PDF File Conversion

This is about converting "Word to PDF" and not "PDF to Word"......there are many free softwares floating around the web for the latter case but in former case they are trial versions,and if not trial then they don't work fine.

Sometimes PDF files come more handy than Word files.Though Word files can be easily edited but are prone to some problems like,

1. Carrying them in pen drive makes the vulnerable to virus,thus data may be lost.

2. In the case when you print Word files that have been prepared on different system,these files are prone to changes in the settings you made.Thus you may end up reworking the whole document all over again.

3. Sometimes the too easy modification/editing ability of word files is also the problem.If you want that no one can edit the document but the document is also not that important then word files are not a better option.

The key is Adobe Distiller. Distiller is part of the Adobe Acrobat family of products. Distiller is the main engine for turning PostScript files into PDF documents. Although there are other programs for generating PDF files, Distiller is the primary one.

The download Link is HERE.

Working with Distiller -

1. Download and Install Distiller.
2. Open the Word document that needs to be converted.
3. Press "Ctrl+P" or choose "print" option from the file menu.
4. In the Print Dialog Box that appears,choose the printer "name" option as Distiller/Acrobat Distiller.
5. Click OK.In the "Save PDF as" dialog box that appears enter the name with which you want to save the word file as a PDF file.Click "Save" option and you are done.......

The Best Antivirus Solution.....

This post will definitely help all those out there who have been looking for a good antivirus.....and that to full version,with no cracks,registry tweaks,etc.......original license way.......

Here I present ESET Nod32 plus its "key finder software"(MiNODLogin),so that you just get licenses at your screen without searching around the web.....

Why ESET Nod32 ??
Coz it's the best.Believe me I have tried all......
Norton....don't talk about it,it ruins the system,as if it were built to run only norton and nothing else.
Avast.......the most ugliest antivirus program,It is fast but don't know if it catches any viruses.
Kaspersky.....a bit faster than norton but slower than avast...also doesn't detect some of the viruses.
AVG........I don't like its interface and not easily available as full version.

ESET nod32 detects all viruses...the "new folder","autorun.inf",etc.
Its fast like avast and powerful like norton.Besides you don't need to worry about license.ESET Antivirus License Finder (MiNODLogin) finds the license keys for you to use ESET as full version.....

Also like Avast and AVG,ESET Nod32 can be updated in offline mode,i.e,you don't need to have internet connection to your system.To do so there is a software called "ESET Virtual Update Server (MiNODServer)".

1. Download and Install the setup --
You can download and then install the setup file from the official website of ESET.
Note: Don't go for ESET smart security....Go for ESET Antivirus.....
http://www.eset.com/download/free_trial_download_int.php

Here you can select the setup file that suits your systems configuration.These setup files are the most updated ones available throughout the web.

2. ESET MiNODlogin --
Here's the software download link
ESET Antivirus License Finder (MiNODLogin)

You need to install java in your system for this software to work.Here's the java link
JAVA Setup

After installing  java and downloading Minodlogin just install the .exe file.You should then be able to run the software from shortcut on desktop.
The system must be connected to internet.Once you run the software,a window will appear where some sites will be enlisted.
Simply expand any one of the site (by clicking on the "+" sign before each of them).Now you will see the keys (User names and passwords).Copy and paste any key in ESET.
You are now a registered user and can "update" the virus database as well as "upgrade" to full version.

3. ESET MiNODserver --
Sorry folks,I tried n googled but this software is not available in english.It is in some european language,so until it is available in english,you need to have internet connection to be able to update ESET.....

DBAF Comic by Toyble

DBAF, where the "AF" stands for "After Future" or "Another Future", is the new Dragonball Series after the DBGT. It is not an official series of Dragonball,as admitted by Akira Toriyama, the creator of DB_Z_GT. But is a Fanfic Art, created by the fans of DB_Z_GT who were not willing to accept the end of Dragonball Series.

There are many versions of DBAF floating around the web, but one of the manga fan named TOYBLE has done a job that is truly appreciable. He publishes the Comic pages on his blog http://blog.livedoor.jp/toyble/ (Less frequently though). The characters drawn by him are just the same as found in DB_Z_GT. The comic is simply awesome.
Have a look. Vegeta at Super Saiyan level 4 being attacked by XICOR (a Super Saiyan 5).

I, being a "big" fan too, thereby post here the latest pages from the comic.

Some how, Toyble has not been able to continue the work and has paused publishing new images. The story is yet to end :(  But for the time being, to have an ending to the story in some sense, he has released an extra volume.

HOW TO INSTALL WINDOWS VISTA/7 USING PEN DRIVE

I had earlier posted on how to Install Windows XP using a Pen Drive.
This post would help you Installing Windows Vista/7 using Pen Drive.

The need is same as earlier. A crashed system requires fresh windows installation and unfortunately CD-DVD Drive is also sailing in the same boat, thus use a Pen Drive.

Although XP installation takes longer time than CD/DVD,Windows Vista/7 installaion on the other hand is faster than DVD disc.This is because XP installtion environment does not have latest USB 2.0 drivers, but Vista/7 does.


REQUIREMENTS :

• USB-Boot enabled BIOS.
• A Pen Drive (Atleast 4GB).
• Windows Vista/7 Installation Files (As DVD Image File or RAR/ZIP Compressed File)
• MBRwiz2.0 (Download).
• UltraISO,a CD-ROM drive emulator (Download). 

NOTE : The Vista/7 installation files can be obtained by downloading a DVD-image file from internet. Alternatively there are rar or zip files available on internet which have the installation files in compressed form. In latter case the "UltraISO" software is not required.


1) SETTING UP BIOS

Before anything is done,check if your BIOS allows USB-BOOTING.

Refer to my post "Setting Up BIOS for Booting from Pen Drive or External HDD" to enable booting from Pen Drive.


2) FORMATTING PEN DRIVE

The Pen Drive should be formatted in NTFS to install Windows Vista/7.
If you are working on Vista/7 then simply format the Pen Drive in NTFS file system.

But if you are working on XP then you don't find the NTFS option while formatting a Pen Drive.
Follow these steps :

• Right click My Computer icon on desktop (it is also found in start menu).
• In the Tools tab,click Device Manager.
• A number of system components are listed here.Click on Disk Drives.
• Right click your Pen Drive in the Sub Menu of Disk Drives and choose properties.

• In the window that pops up,go to the Policies Tab.
• Under this check the option "Optimize for performance".

Now if you go for formatting the Pen Drive then NTFS option will be present.

3)) PREPARING BOOTABLE PEN DRIVE

The whole thing is just making Pen Drive bootable.Rest all installation is exactly same as with DVD disc.
Before making Pen Drive Bootable,it must be made an Active Partition.After that it can be made bootable.

# SETTING PEN DRIVE AS ACTIVE PARTITION

   If You Are Working On XP


Download the file MBRwiz2.0 and extract to a folder (i extract to the directory d:/temp).

1. Open command prompt(cmd).

2. Use command 'cd' to go to the directory where you extracted MBRwiz2.0 (as shown below,Click the image for zoomed view).Then type the following command "mbrwiz /list" (all commands must be typed without the quotes) as shown in red box and press ENTER.

3. Once you do so,it will dislpay all the storage devices connected to the system and their respective partitions,here "disk 1" is the Pen Drive (if no other pen drive/usb Hdds are connected).By default the active parameter is set to "no" for Disk 1(shown in red box below).Now type the command "mbrwiz /disk=1 /active=1" and press ENTER.

Note : the command should be typed as it is,be careful with spaces too.

4. Now it will ask for confirmation.Type 'y'.Then the screen should look as below

5. Now the Pen Drive is an active partition and can be made bootable.

Also in step 3 if you type command "mbrwiz /disk=1 /active=0" then the pen drive will become inactive partition as it was earlier.



   If You Are Working On Vista/7 

• Plug in the Pen Drive.
• Go to Start Menu and type "cmd".The cmd icon appears in list.
• Right Click the cmd icon and choose "Run as administrator",click "yes" on the next UAC window (User Account Control).
• Type "diskpart" and press ENTER.
• Type "list disk" and press ENTER.This will  list down all storage disks connected to the system,even your HDD.Note the Disk No. for your Pen Drive (usually it is Disk 1 if no other pen drives and external hdd's are connected).
• Type "select disk x" and press ENTER,where "x" is your disk no. of your pen drive.This will select your Pen Drive.The screen should look as below till this step.

• Type "list partition" and press ENTER.This will list down the partitions on your pen drive (usually there is only one partition with no. "1").
• Type "select partition 1" and press ENTER.This will select the only partition on your Pen Drive.
• Now type "active" and press ENTER.This makes the pen drive active partition.To make it inactive simply type "inactive" instead of "active".The screen now should be as below.

• Exit cmd

Note : The Pen Drive is not bootable now,it is an Active Partition.Only an Active Partition can be made bootable.

Now simply extract the Windows Vista/7 installation files to a folder named "win" on desktop if you have the rar/zip file of Windows Vista/7 DVD.

But if you have a DVD Image file of the Windows Vista/7 DVD,then you need a Virtual CD-DVD drive Emulator.Download and Install UltraISO and mount  the image file on virtual drive and then copy the files to folder "win" on desktop.

A small tutorial to work with UltraISO :

• After installing,go to My Computer.
• There you will find an extra virtual CD-ROM drive.Right click this drive.
• In the subsequent selection menu there will be an option "UltraISO".Choose it.
• Another sub menu will pop out.Choose the option "Mount" here.
• A window will appear where you can browse your cd-image file.
• Browse it and click OK.Your CD-IMAGE FILE is now mounted on to the drive.
• Open the drive and copy all files to "win" folder on desktop.

# MAKING PEN DRIVE BOOTABLE

FOR VISTA/7 -

• Open cmd by "run as administrator" option.By default the current directory is "c:/windows/system32".We have to change this directory to desktop.
• First type "cd\" and press ENTER.This will take you to root directory,i.e,C:
• Now type "cd users/xxxx/desktop" and press ENTER.Here "xxxx" is your User Name with which you logged into Windows.
• Type "cd win/boot" and press ENTER.
• Then type "bootsect /nt60 x:" and press ENTER.Here "x" is the drive letter for your Pen Drive.Once you hit ENTER the screen should look as below

• Exit cmd.

 FOR XP -

• Open cmd.
• Type "cd desktop/win/boot" and press ENTER.
• Then type "bootsect /nt60 x:" and press ENTER.Here "x" is the drive letter for your Pen Drive.The results should be same as above.
• Exit cmd.

NOW JUST COPY ALL THE CONTENTS OF "WIN" FOLDER TO YOUR PEN DRIVE.
IT IS FINALLY READY TO INSTALL WINDOWS VISTA OR WINDOWS 7.

JUST RESTART SYSTEM WITH PEN DRIVE PLUGGED IN AND INSTALL WINDOWS AS YOU WOULD DO USING A DVD.
CHECK OUT THE SPEED!!!!

SETTING UP BIOS FOR BOOTING FROM PEN DRIVE OR EXTERNAL HDD

What we have to do here is to enable our system to boot from USB Pen Drive.
Before going to details you must check if you really need to change settings in BIOS.
Just press the key (when you start the system with Pen Drive inserted) that opens the boot sequence.This key is generally F10,F12,ESC,etc.

Here if your Pen Drive is listed in the sequence then simply select it to boot.
But if not then read on....

Note : The BIOS(Basic Input Output Setup) varies from PC to PC.Yours may be different (still you could get some "how about" of setting up BIOS from this post).Also some BIOS do not support USB booting (then this tutorial will not help you).


Note of Caution : First read the full post and then try.

The steps are :
1.   Power on your PC and press the key required to enter BIOS setup.This Key is usually F2,DEL or F11 on different systems and is displayed at the first screen when system starts.
At first the screen should look as below

2.   Go to the BOOT option using the right-left arrow keys shown in green box below.
Note: Some system's BIOS do not show the BOOT option.In that case you will find the BOOT ORDER (what we are actually looking for) in some other option.

Once you have found the Boot Order,then it might be that your USB Pen Drive/HDD is disabled from boot order as shown in yellow box.
Using the options shown on the right pane of the screen (in red boxes) you can enable the device (here 'x' is used to enable/disable the device from boot order).

Note : Every system on startup scans for booting devices according to the boot order setup in BIOS.Your system's hard disk is also one of them (usually starting with IDE HDD.....).
Here just make sure that your pen drive is above your system's hdd in boot priority order.This can be done again by using options in the right pane (here F5 and F6 are used to decrease and increase the priority respectively).
If everything has been done right then screen should look as below,with USB device at the top (in red box).

Note : On some BIOS the procedure to change boot priority and enable/disable is not as simple as here.Those who are new to this must not try this as it may damage your system.

3.   After doing so go to the Exit option and exit saving the changes.
 

Now your system is ready to boot from Pen Drive.
