Thành viên:Nguyenthephuc/Note: Tùy chỉnh boot trong win7

Yesterday, I had installed Windows 7 Beta Build 7000 on my Lenovo Ideapad S10 Netbook. The S10 netbookwas pre-installed with Microsoft Windows XP Home Edition. So, I set up XP/ Windows 7 dualboot. The Windows 7 installer set the default boot choice to Windows 7 and renamed the XP as “Previous version of Windows”, also a timeout of 30sec set.

If you try to modify the boot options the oldfashioned with boot.ini file, you get the following warnings:

;Warning: Boot.ini is used on Windows XP and earlier operating systems.

;Warning: Use BCDEDIT.exe to modify Windows Vista boot options.

If you examine, Windows 7 doesn't have NTFS write permissions on XP system partition, even though it creates a "boot sector" inside it, cause it is the first one in line on the system disk, which is shared half on half by both systems.

So I booted into Windows 7, and run the following commands:

By default Vista/Windows 7 open command prompt in user mode, so we need to change the permission. To do so, just execute this command:

Start Menu > All Programs > Accessories > Command prompt (right-click & "Run as administrator")

bcdedit /set {legacy} Description "Microsoft Windows XP Home Edition SP3"

(Changes the text description of the "Legacy" OS line in the boot menu. The quotation marks must be included in the command)

bcdedit /default {legacy}

(Sets the legacy (Windows XP) OS as {default} boot item)

bcdedit /? (shows all commands one is able to use)
