How does pressing “R” helps my computer without replacing my hard disk?

How does pressing "R" help my computer without replacing my hard disk? I tried to replace the OS of my Intel Celeron computer from Windows XP service pack 2 into Windows Crystal XP 2007. I thought it was successful but it was not .

And now, I cannot return it to the 1st Windows XP so, it always reboots.

It shows an error message NTLDR missing press ctrl+alt+del to restart. I tried reinstalling and repairing the operating system but it says "press 'R'" and then it always goes to the recovery disk.

What's the problem with this?

Hello catherineO!

Actually, pressing R doesn't help the computer without replacing your hard disk. The thing you must do is to start the PC in safe mode by pressing F8. There, you will find the option of startup and select the safe mode. Sometimes, it may not work. While inserting the windows CD in the CD ROM, try to boot the Operating System again on the C drive. Before doing this, format the C drive first. After that, go to the Bios setting then select Boot device priority to your hard disk (not the CD ROM as it was before).

This will help you get rid of your problem.

Hi CatherineO!

When an error message shows "NTLDR is missing pres CTRL+ALT+DEL to restart" it means that:

  • Computer hard disk drive is not properly setup in BIOS.
  • Corrupt NTLDR and NTDETECT.COM file.
  • Misconfiguration with the boot.ini file.
  • Seriously corrupted version of Windows 2000 or Windows XP.
  • Loose or Faulty IDE/EIDE hard disk drive cable.

And from your case, it is basically caused by a seriously corrupted version of Windows 2000 or Windows XP maybe due to a system crash during installation of your OS, to a bad installation copy of your OS, or to an error that transpired during installation.


Pressing "R"  brings you to an alternative where you can access the hard drive. From there, you can recover your OS from times that it does not boot. Besides that, you can perform certain tasks using a command line interface. However, this method is only available where NTLDR loads. In your case, you can use this option to repair your problem.

1. Insert your Windows XP installation disc (bootable  which in most cd's are bootable)

2. When the screen displays "press any key to boot from the CD", press any key to continue.

3. Once you are in the Windows XP installation screen or the setup menu, press "R" to proceed to the recovery console and, repair your Windows.

4. From there, go into your Windows installation by pressing the "1" key and then press enter.

5. You will be asked for your administrator password. Enter the password.

6. Copy the below two files to the root directory of the primary hard disk. The format of the task would be:

<COPY command> <space> <drive letter of your CD/DVD drive and the location of the file> <space> <drive letter of your primary hard disk or your primary partition which in most cases is drive letter C>

For example,

             copy e:i386ntldr c:

             copy c:

NOTE: Drive letters would vary in your computer.

7. After both of these files have been successfully copied, remove the CD and then reboot it.


Another way would be reformatting your hard disk; however, it would be very risky since it erases all of your files. Having a fresh and new installation would probably get rid of this problem. Besides, it removes and deletes all the corrupt files that could run down and slow down your computer.

Either way, these solutions can repair your problem along with your OS.
