Regarding the matter "unable to boot", I got a solution. Use the following
procedure to create this disk:
1.. Place a blank floppy disk in drive A, and format the disk by using
Windows XP.
2.. From the root folder of the system partition of your hard disk drive
(for example, C:\-), copy the following files to the floppy disk:
Boot.ini
NTLDR
Ntdetect.com
You may have to remove the hidden, system, and read-only attributes from
the files.
3.. Restore the hidden, system, and read-only attributes to the files on
your hard disk if you removed these attributes.
4.. If either the Bootsect.dos or the Ntbootdd.sys file resides in the
system partition, also use the procedure that is described in steps 2
through 4 to copy these files to the boot disk.
If you format a floppy disk in Windows XP, the boot record points to the
NTLDR file. When NTLDR runs, it loads the available operating system
selections from the Boot.ini file. If you select Windows, NTLDR runs
Ntdetect.com, and then passes control to Osloader.exe. If you select MS-DOS
or OS/2, NTLDR loads Bootsect.dos.
