Hi
To "format C" means to format the the C drive, or the primary partition that Windows or your other operating system is installed on. When you format C, you erase the operating system and other information on the C drive.
However, it's not a straightforward process to format C. You can't format the C drive like you can format another drive in Windows because you're within Windows when you perform the format. To format C from within Windows would be like lifting a chair in the air while sitting on it - you can't do it.
The solution is to format C from outside of Windows, meaning you need a way to format a drive from somewhere other than your Windows installation. The easiest way to do this is to boot to an operating system (with formatting abilities) from a CD/DVD/BD drive, flash drive, or floppy drive.
This might all sound very complicated but it's actually quite easy to format C. Below are 5 completely free ways to format your C drive:
Note: If you're trying to format your C drive because you want to replace or reinstall Windows, you do not need to format C ahead of time. Formatting is done automatically during the Windows installation. Skip this article entirely and instead see How To Clean Install Windows.
Important: Formatting your C drive does not permanently erase the data on the drive. If you want to completely erase the information on the C drive, see Option 5 below, Wipe the Drive Clean With Data Destruction Software.
1. Format C From a Windows Setup Disc
The easiest way to format C is by completing part of a Windows installation. It's not easiest as far as number of steps goes, but since most of us have a Windows Setup DVD lying around, we have easy access to a means to format drives outside of Windows.
Important: You can only format C this way using a Windows 7 Setup disc or a Windows Vista Setup disc.
However, it doesn't at all matter what Windows operating system is on your C drive, including Windows XP. The only requirement is the disc you use to format C - either a Windows 7 or a Windows Vista Setup DVD. Feel free to borrow a friend's disc if you'd like to try this method but you only have Windows XP... or some other operating system.
2. Format C From a System Repair Disc
If you don't have access to a Windows Setup DVD, but you do still have access to a working copy of Windows 7, you can create a System Repair Disc and then boot to that disc and format C from there.
You can only format C using a System Repair Disc if you have access to Windows 7 to create the System Repair Disc. If you don't have access to Windows 7, find someone who does and create the repair disc from their computer.
Note: A System Repair Disc created from Windows 7 can format a C drive that has any Windows operating system on it, including Windows XP or Windows Vista.
3. Format C From Recovery Console
If you have a Windows XP Setup CD, you can format C from the Recovery Console.
The biggest caveat here is that you must also have Windows XP installed on your C drive. However, if you don't have access to Windows 7 or Windows Vista, this option may be your best to format C.
This Recovery Console method to format C also applies to Windows 2000. Recovery Console does not exist in Windows Vista or later, nor does it exist in Windows ME, Windows 98, or earlier.

What you need is bootable DVD/CD for installing or repairing Windows 7 to get missing 'bootmgr' or repair corrupted bootmgr...If there are files corrupt on your CD, you can get new one from shop you have purchased..Maybe just need to clean up your DVD/CD, so your DVD drives can read properly the files installation..

Hello, this is how I dual boot my laptop with windows xp and windows 7

1. Backup all you important files, use an external hard-disk if possible
2. Make sure you have two drives or partitions: usually drive C and D
3. Insert your xp cd, do a quick format of drive C and install
4. Boot into windows xp and format format drive D if necessary
5. Insert your windows 7 DVD and follow the prompts. When it asks you to upgrade or new install, choose new installation
6. When you are asked to choose a location choose drive D
7. Complete your windows 7 installation
8. Thats it, you can now install drivers and programs

When installation is complete you will see both os options: windows 7 and previous version of windows (i.e xp)

I have done this numerous times without the need for any other step or software. The only rule is to is to install xp first, then windows 7.

All the best

Hi there !

Your windows operating dvd installer is damage. It just the CD/DVDROM drive cannot read your DVD installer because it have too many scatches in your DVD. Just get new OS dvd installer and repair your windows 7 operating system or reinstall the operating system.

change your rebbot to f12 if its already f2 its not going to read it theres error on f2.

1. If you are just setting up your computer to have an a regular HDD and Backup HDD, i would think you should be able to set that up by booting onto your computer regularly, go to start, then into My Computer and right clicking on the HDD you want to set as Raid 1.

But if just want that other HDD for Space on your computer, all you had to do was plug it in and there you go... extra space.

Now if your installing windows 7 on the other drive i would find that pointless because you already have it on your first drive unless your putting 2 operating systems onto your computer.

Hope this helps.

Heres the solution to that problem.
