boot record
First start the PC and then press f2 for bios then boot to CD/DVD
The BOOTMGR is a program that runs when you start your PC, and loads your operating system from the hard drive. When it is missing, Windows is unable to boot.
To do this (assuming you have a bootable DVD ROM - i.e. one with an operating system on it), you need to tell your PC's BIOS to look at he DVD drive during the boot sequence and make this the first drive to try and boot from. To do this you need to get into the BIOS menue - you PC manual will tell you how to do this but you can also try pressing the one of the 'F2', 'F8', 'F9' or 'F12' keys while the PC is starting up (before windows loads), one of these should work! - and change the boot menue options.
The BIOS( basic input-output system) software is built into the PC, and is the first code run by a PC when powered on ('boot firmware'). When the PC starts up, the first job for the BIOS is the power-on self-test(POST), which initializes and identifies system devices such as the video display card, keyboard and mouse,hard disk drive, optical disc drive and other hardware. The BIOS then locates boot loader software held on a peripheral device (designated as a 'boot device'), such as a hard disk or a CD/DVD, and loads and executes that software, giving it control of the PC.[2] This process is known asbooting, or booting up, which is short for bootstrapping.
