Fix the Boot.ini missing problem

If the system file is installed in the root of C drive, you still can start your computer with the Boot.ini missing, while it's not in C drive, you can't do it. Actually, as single system users, the system file is always installed in the root of C drive. Then how to fix this Boot.ini file missing problem? Here's the solution for you.

4. Now copy and paste the following code in it.
[boot loader]
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)WINDOWS="Microsoft Windows XP Professional"/fastdetect

When the boot menu is started and users didn't do any operation in 30 seconds, then it will access the default system automatically. 30 seconds is the default time, if you only have one system, you can set it as 0. Or set other time you think it's OK if you have multiple systems.
This is the default system.
This part is always the one we edit. Partition (1) means the first partition, usually the C drive, and WINDOWS is the system folder. If you want to set XP in the D drive as your default system, you should edit it as partition(2)WINDOWS. multi(0)disk(0)rdisk(0)partition(1)WINDOWS="Microsoft Windows XP Professional"/fastdetect This part is the same as the "default" part, and Microsoft Windows XP Professional is the name of the system.
/fastdetect: lots of websites recommend to edit as "nodetect".

5. Click "Save" and exit.
6. A new file boot.ini will be created in the C drive on your computer, now we need to give it system attributes.
7. Open command prompt (click "Start" on your computer, and type "cmd" in the run box).
8. Then type the following command
attrib C:oot.ini +s +h
and press "Enter".
9. You've solved the problem now.
