If you are unable to boot into windows using either the regular startup method or by entering safe mode, the best option is to boot into Windows using a recovery disk. These are often supplied by computer manufacturers, however if you have not got one, any Windows XP disk will do, as long as it is the same version of XP that is on the computer unable to boot.
This disk will offer you the option of using a recovery tool instead of installing a new copy of Windows, which will enable you to fix whatever it was in the Windows install that went wrong. Should this not work, there may be an underlying hardware error, or you may need to install a fresh copy of Windows onto the computer. This is an easy process, however you will lose your data should you choose to take this option - removing the hard drive and backing it up is always a good idea before reinstalling the operating system.
There is a third alternative, although this one may not help you boot back into Windows so much as help you recover files. Download a distribution of Linux (I recommend Ubuntu) and burn the image onto a CD or install it on a USB drive. Put the CD into the computer and boot into the LiveCD. This will give you access to your hard drive which will let you back everything up without taking the hard drive out of the computer - you will need an external hard drive or similar to move the files onto however.
normally that's the CD you used to install windows
Following are the boot loader features of windows 7: a) Windows Boot Manager(Bootmgr.exe) b) Windows Operating System loader c) Windows Resume Loader

Normally, the computer will not boot. And you will have to reinstall Windows XP.
Boot Camp allows you to install Windows on your Mac and dual boot. Your Mac will look just like a Windows PC when you boot into the Windows partition. You will also have to install Windows Security on that partition to be safe.
== == You might be able to get Windows to boot into Safe Mode. As soon as you press the power button, begin pressing the F5 key, over and over again, until the computer begins to beep. (If it does. Some won't.) This should bypass the files that Windows normally boots from, and boot Windows into Safe Mode. If you are successful, look at the contents of 'C' drive to find out if any files have been added, or changed. You may need an experienced Windows technician to help you.
NTLDR is indeed a key boot file in Windows 2000 and all of the Windows operating systems since Windows NT. A machine will not boot without that file.
Boot from the Windows setup DVD
You can partition your hard drive and install Windows Server onto the partitioned space. You then can boot up from either Windows 7 or Windows Server.
I suggest installing Windows, and then Linux (preferably on different physical hard drives). When Windows is installed it tends to overwrite the boot partition, making it difficult to boot linux afterwards.
you will have to boot up your computer from the windows 7 DVD and repair the installation (I guess its called startup repair). OR If you have Windows XP installed on the same PC, then use Vista Boot PRO (Totally free) to restore Boot manager info to your windows 7 partition
