How to Encrypt and Hide Your Entire Operating System from Prying Eyes



Iif you're really serious about protecting your data, you can actually hide your entire operating system. Here's exactly how to do it. To accomplish this task, we'll be using True Crypt, our favorite free and open-source disk encryption software that runs on all platforms, supports hidden volumes, and can even encrypt your entire hard drive.

 Once we've completed the setup, you'll have two Windows installations and two passwords. One password will activate a hidden Windows installation as your real operating system, and the other, a decoy install to throw intruders off the trail.

Setting Up Your Hidden Operating System

In order to actually activate the hidden operating system features, you'll need to make sure that your hard drive is partitioned in a very particular way: You'll need two partitions on your drive, and the first partition has to have your Windows install on it. The second partition needs to be bigger than the first, and if you're using NTFS as your file system, it will need to be at least 2.1 times as big as the first partition. You can re-partition your current drive, but your best bet will be a clean installation. (As with skinning a cat, there are many ways to partition a hard drive. Windows 7 and Vista have built in partitioning tools [open Computer Management, then go to Storage -> Disk Management in the sidebar], or you could check out our guide to dual booting windows 7 as a solid resource to get started with a partitioned system.)


Once you've got your Windows installation up and running, make sure you've downloaded and installed TrueCrypt on your machine. Then fire it up and use the System –> Create Hidden Operating System menu item.

This will pop up a wizard that will help create the new TrueCrypt volume to house the hidden operating system, which will live inside of a hidden volume on the secondary partition. Your best bet the first time around is to just choose Single-boot—leave the multi-boot for the advanced class.
The Volume Encryption options page is important for one primary reason, namely that you need to choose the same encryption method across the board while you're running through this process. You'll be prompted a number of times to choose the encryption, and you need to always choose the same one or else you can't boot or access your data—also, the default setting of AES encryption is much, much faster than any other option.
You'll be prompted to choose the outer volume password, which will house a set of decoy files to make people believe that your TrueCrypt volume on the second partition contains nothing more than a bunch of files you don't want people to see—except the files you put on the outer volume aren't actually meant to be a secret. Make sure you don't lose this password.

Load and use multiple OSs from your USB drive



Ever felt like carrying your Ubuntu, Fedora, Tiny-core and all other OS’s iso in your pen drive? Yes, you can now carry all your favorite Operating systems with you wherever  you go and boot from them using the same USB drive.MultiBoot USB is a freeware which can help you to use the multiple OS iso files on the same pen drive.

To use the MultiBoot on your pen drive it must meet some requirements first. You’ll require a FAT32 formatted pen drive and a computer which can boot from a USB device. Prefer using an 8-16 GB pen drive so that you can have more different operating systems on it.

To start off first download the MultiBootISO’s from here . Run the executable and follow the instructions. Browse to the ISO file you want to load on your USB drive and build the bootable USB using it. You might have to format your pen drive during the process so do take a backup of all your data which is there on the pen drive.

To add more ISO files repeat the same procedure. Restart your PC and set the highest priority for the USB drive to boot from it and done. Do give it a shot!!! :)

Knoppix - bootable CD



KNOPPIX is a bootable CD with a collection of GNU/Linux software, automatic hardware detection, and support for many graphics cards, sound cards, SCSI and USB devices and other peripherals. KNOPPIX can be used as a Linux demo, educational CD, rescue system, or adapted and used as a platform for commercial software product demos. It is not necessary to install anything on a hard disk. Due to on-the-fly decompression, the CD can have up to 2 GB of executable software installed on it.

Ubuntu - Best Open source linux operating system



Ubuntu is a computer operating system originally based on the Debian GNU/Linux distribution and distributed as free and open source software with additional proprietary software available.

Ubuntu comes installed with a wide range of software that includes OpenOffice.org, Firefox, Empathy (Pidgin in versions before 9.10), Transmission, GIMP, and several lightweight games (such as Sudoku and chess). Additional software that is not installed by default can be downloaded and installed using the Ubuntu Software Center or the package manager Synaptic, which come pre-installed. Ubuntu allows networking ports to be closed using its firewall, with customized port selection available. End-users can install Gufw (GUI for Uncomplicated Firewall) and keep it enabled.[31] GNOME (the current default desktop) offers support for more than 46 languages. Ubuntu can also run many programs designed for Microsoft Windows (such as Microsoft Office), through Wine or using a Virtual Machine (such as VMware Workstation or VirtualBox).

Installation of Ubuntu is generally performed with the Live CD. The Ubuntu OS can be run directly from the CD (albeit with a significant performance loss), allowing a user to "test-drive" the OS for hardware compatibility and driver support. The CD also contains the Ubiquity installer,[33] which then can guide the user through the permanent installation process. CD images of all current and past versions are available for download at the Ubuntu web site. Installing from the CD requires a minimum of 256 MiB of RAM.

Users can download a disk image (.iso) of the CD, which can then either be written to a physical medium (CD or DVD), or optionally run directly from a hard drive (via UNetbootin or GRUB). Ubuntu is also available on ARM, PowerPC, SPARC, and IA-64 platforms, although none but ARM are officially supported

Wubi, which is included as an option on the Live CD, allows Ubuntu to be installed and run from within a virtual Windows loop device (as a large image file that is managed like any other Windows program via the Windows Control Panel). This method requires no partitioning of a Windows user's hard drive. Wubi also makes use of the Migration Assistant to import users' settings. It is only useful for Windows users and it also incurs a slight performance loss.

We thank and appreciate Hiren for his great BootCD. This site is just a download place for Hiren's BootCD and is not related with Hiren. For developer's homepage please visit Hiren's Homepage under the links.
Partition Tools.

If you need to make changes to the partitions on your computer, there are several applications that provides various levels of functionality for accomplishing this goal. You can both create and delete partitions from your computer, even while there are other partitions on the hard drive you are modifying.
