"Please select the operating system to start"

kalimat diatas selalu muncul pada saat booting.
ini terjadi setelah saya install windows via USB.

solusi :
ya dengan mengedit file boot.ini

file boot.ini di windows saya kurang lebih seperti ini:

[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="Microsoft Windows XP profesional" / noexcute=option / fastdetect
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="USB Repair NOT to Start Microsoft windows xp profesional" /noexcute=option / fastdetect



To access the boot.ini file, click Start, right-click My Computer, select Properties > Advanced, then click the Settings button under Startup And Recovery. In the Startup And Recovery dialog, click the Edit button under System Startup. This will open the boot.ini file with Windows' Notepad program.

To open the file without the long string of dialogs (using Notepad or another text editor), you must first remove the file's read-only attribute.

To do so, click Start > Run and type cmd. Click OK, and you'll see a command-line dialog. At the command prompt, type CD\, then press Enter. Now type attrib -r -a -s -h boot.ini (note the spaces between command letters and the hyphen for the next letter) and press Enter.
This will remove file attributes that would prevent you from editing the file. Next, type notepad boot.ini and press Enter to open and edit the file.

Now, to remove the Windows 98 boot option, simply delete this line: multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="USB Repair NOT to Start Microsoft windows xp profesional" /noexcute=option / fastdetect
, Windows XP becomes the default start-up OS. If you prefer to leave the dual-boot feature as is, but you want Windows to start the default operating system sooner, simply replace the number after Timeout= to something less than 30 seconds. (Windows will present you with a dual-boot option, but it will launch XP within the time you specify.) When you have completed your edit, save the file and close Notepad.
