There may be many a purpose for which one need to boot from a cd, dvd, or a bd. Most often, for running advanced tools such as password recovery tools and memory tasting programs, the Boot cd is used frequently. One must need booting from a disc planning to reinstall windows or even run repair tools such as recovery console or startup repairs. While one boots from a disc, what actually takes place is running a small operating system that is already installed in the hard drive such as Linux, or windows.

Following some specific steps, booting from a cd is possible. It is an easy process and does not take much time. Generally, booting from the dvd, cd, or bd takes around 10 minutes of time. For doing the same operation, the first thing that one would require is a bootable cd, or dvd. Next, he/she has to change the order of the boot in BIOS so that the dvd, cd, or bd drive is listed first. Some of the computers are configured following this procedure, but others are not. If the optical drive does not come in the beginning in the boot order, the system will start normally, without checking what is inside the disk drive.

While running the above operation, one should be conscious so that after installing the optical drive in form of the primary boot device in the BIOS, the computer system will check for the particular boot cd or drive, each time whenever the computers starts. Configuring the personal computer following the way generally do not cause any specific problem unless one requires to leave a cd or a disc in the drive all the time.

Next after the above step, one needs to insert the Bootable cd, bd, or dvd into the disk drive. Well, before doing this function, one must know beforehand whether the disk is bootable. The simplest way to detect this is by inserting the same into the drive and following the remainder of the instructions flashing on the screen. Most of the operating systems install cds and dvds that bootable.

After inserting the above drive, one has to restart the computer. An instruction, press any key would flash on the screen requiring to boot from cd or dvd. While booting to a windows setup cd or disc, along with other bootable cd, one might be prompted to boot from the disk or the cd, one need to press any key on the keyboard within a few seconds the message arrives on the screen. It is necessary, or unless the system would look for boot information upon the subsequent boot device in the list of the BIOS that probably rests on the hard drive. The computer now starts booting from the boot usb or cd, dvd, or the bd disc. While doing the booting, one must check for the boot order in the BIOS. In addition, one must clean the disk properly before running the program. Following the above process, the booting can be done easily.
