How to recover when windows XP won’t boot after a defrag.

Over the weekend, my laptop was running slow so I decided to run defrag after about 10 hours of it running I decided to cancel the defrag and rebooted my system. The system gave an error similar to “Windows XP can not boot required DLL missing”.

So these are the steps used to recover my system.
1. I inserted my windows XP installation disk and rebooted my laptop.
2. When my laptop was booting I pressed the required key to have it boot from CD drive, instead of booting from the hard drive.
3. After the Windows XP booted from CD, I ran the “Recovery Console” (Press R from the menu)
4. I typed: Chkdsk
5. I typed: bootcfg /rebuild
6. Then I rebooted and it worked.
