Assuming you using XP
Boot from your XP disk skip the first option that will ask you to press R to repair Windows. After pressing F8 to agree it will show you the installed OS now press R to repair the OS. This should recreate the system files...

You must boot the computer FROM AN XP CD.

How to do an XP Repair installation of Windows, step by step:
http://www.windowsreinstall.com/win...

If your hard drive Windows is loading from is SATA or SATA II, if the CD or Setup doesn't find your hard drive, you won't have the Repair choice because it can't find a Windows installation - you will need to do one of:

- easiest - set the mboard's bios Setup so that the SATA controllers are in an IDE compatibility mode of some sort. If you can't figure out how to do that, we need the model of your brand name system, or the model of your mboard in a generic desktop system to be able to possibly help you with that.
Then Setup will recognize SATA drives as IDE compatible drives. If you want to have the SATA drives running in their SATA mode, you can set the bios to have the SATA controllers in a SATA mode after you have installed the SATA drivers in the operating system, if they haven't already been installed.

- or - you need to press F6 at the beginning of loading files from the CD, and provide the driver file(s) on a floppy disk in a legacy floppy drive when prompted. The files that have been loaded from the CD at that point cannot recognize most USB floppy drive models, and can't look on USB drives, on other hard drives or on other hard drive partitions on the same hard drive, or on disks in CD or DVD drives for driver files.
Most desktop mboards have a floppy drive data header, even when you don't have a legacy floppy drive installed.

- or - you have to make yourself a "slipstreamed" CD - preferably a CD-R - that has the SATA controller driver files for your mboard that you need integrated into the Windows contents - if your CD does not have SP3 updates included, you might as well integrate the SP3 updates into your CD contents while your doing that. Instructions for how to do both of those things are available in many places on the web. You boot the computer from the "slipstreamed" XP CD rather than the original one.

The XP CD you use must be for the same version of XP you have installed - Home or Pro - otherwise you will NOT see the option to Repair Windows when you boot from the XP CD.
(If you have any version of XP MCE, you must have either the two CD MCE set, or a MCE DVD (which may not exist), and you can't complete the Repair installation - bugs in all versions of MCE's Setup prevent it's accepting the second CD as a valid source (both CDs must be inserted in the SAME drive) - if you quit Setup when it won't accept the second CD, Windows will probably then work, if nothing on the second CD was required to fix the problem. )

If you have a brand name computer, if it came with one or more Recovery CDs, or DVDs , usually one of them is labelled as an XP operating system re-installation disk or similar - that will work the same as a Microsoft XP CD. That type of disk that came with a different brand name computer model usually CANNOT be used with your model - the CD will probably refuse to load all the files necessary.

You must use an XP CD, or the equivalent, to recover from your problem.

If your model didn't come with any Recovery CDs, or if it did but you're not the original owner and you weren't given them, then

- there is often a program already on the hard drive in the original software installation that you were supposed to use to make yourself Recovery disks, while Windows is working fine. If you can't get into Windows now, then it's too late for you to use that option.

- or - in the case of some el-cheapo brand name systems, or in any case, if your computer model is not more than about 5 years old, you can often order Recovery CDs from the brand name's web site for a lot less money than just an XP CD costs.

"the equivalent"
The Recovery disk, or first Recovery disk in a set, on computers with XP on them usually has nearly identical data on it compared to a Microsoft OEM XP CD, and can be used the same way as a regular XP CD, but probably only on your computer model or a small group of models made at about the same time by the same maker.

If you know someone who has a Microsoft OEM XP CD that is either Home or Pro, whichever is on your computer, you can use that along with the OEM Product Key that's on the official Microsoft label on your computer case.
That type of CD has "For distribution with a new PC only." printed on it

The CD must have at least SP1 updates included on it in order to support recognizing hard drives larger than 137gb manufacturer's size = 128gb in Windows.
CDs with SP2 or SP3 updates in included have SP2 or SP3 printed on them.

If you can't borrow a suitable OEM XP CD from someone, then you're going to need either the Recovery disk(s) for your specific model, or you're going to have to buy yourself a new XP CD. New OEM XP CDs are the cheapest, and can be found on the web, or bought from local places that build custom computer sysrtems and have lots of parts and software, the ones with SP3 updates included costing the most. If the CD you buy is not OEM (does not have "For distribution with a new PC only." printed on it), then you use the Product Key that came with the CD.

Whatever XP CD you get, it must be the same version - Home or Pro - as on your computer in order for you to have the second Repair choice - the Repair installation procedure - if you want to be able to get Windows working properly again without you losing your personal data that is already on the Windows partition.

If you don't care about the personal data you have on the hard drive, you could run a regular Setup from an XP CD from scratch.
If you have to buy a Windows disk, if you don't care about the personal data you have on the hard drive, an OEM Windows 7 DVD costs similar to what an OEM XP CD with SP3 updates costs, but your system must meet at least the minimum hardware requirements - e.g. at the very least you may need more ram.
