This post is an explanation of how to use "Boot Disk" which I call "Emergency Bypass Disk" personally.

When you encountered Windows boot-up trouble, you can boot up Windows XP from this disk.
And Microsoft recommend that you create this disk.
However, you need have at least USB external floppy drive.
The CD version of this disk can be made.
I am going to post how to make the CD version at a later date.

This disk is useful for the following cases.

Figure_1

Several boot-up troubles, missing Ntldr and so on, are caused in "Trouble Zone" of Figure_2 below.

Firure_2

When you boot up your machine from the disk, this disk will avoid "Trouble Zone" in your hard disk and boot up your Windows XP from floppy disk, via blue arrow in Figure_2 above.
If you use Windows XP with NTFS format, I highly recommend that you create this disk before you will encounter a boot up trouble.

■ How to create it.
Refer to the link below:
"How To Create a Boot Disk for an NTFS or FAT Partition in Windows XP"

If you are in Windows boot up trouble, create this disk with other conputer. However, you may need to change "Boot.ini".
If your system is single boot of Windows XP, "Boot.ini" is below.

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Windows XP Home"/fastdetect

If your system is a dual boot of Windows XP and Windows 98([CAUTION] Windows98 is "C:") "Boot.ini" is below.

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(2)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Windows XP Professional"/fastdetect
C:\="Windows 98 Second Edition"

You will be able to see several different of "Boot.ini" on the Web,　I want you to create "Boot.ini" referring to it.

■ How to fix the Windows boot-up troubles.
If you succeeded to boot up Windows from this disk, your trouble is in "Trouble Zone" in Figure_1.
The outline of the trouble is the following. The error messages are not all.
