Common formats are as follows:
[boot loader]
timeout=10
default=multi(0)disk(0)rdisk(0)partition(2)\WINXP
[operating systems]
multi(X)disk(Y)rdisk(Z)partition(Q)\WINXP="Microsoft Windows XP Professional" /fastdetect
SCSI(X)disk(Y)rdisk(Z)partition(Q)\WIN98="Microsoft Windows 98" /fastdetect
The following focuses on the [operating systems] section.
(Q) represents the sequence number of the partition where the operating system's system root directory is located on the main partition on the same fast hard disk (Q starts from 1).
(Z) If starting with multi, then Z represents the hard disk sequence number of the hard disk on the same disk controller (Z starts from 0).
If it starts with SCSI, the Z value is meaningless and always equals 0.
(Y) If it starts with SCSI, then Y port indicates the hard disk sequence number of the hard disk on the same disk controller (Y starts from 0).
If it starts with multi, then the Y value is meaningless and always equals 0.
4. If there are both IDE disks and SCSI disks (or only IDEs) in the computer, and the SCSI setting in the BIOS is set to enable, it starts with multi(X), where X represents the sequence number of the disk controller on the same disk controller where the partition where the operating system's system root directory is located (X counts from 0).
If there is only SCSI controller in the computer, it starts with SCSI(X), where X represents the sequence number of the disk controller on the same disk controller on the partition where the system root directory of the operating system is located (X counts from 0).
/SAFEBOOT: Safe boot, only start the drivers and services in HKLM\System\CurrentControlSetControl\SafeBoot, followed by three parameters Minimal, Network or Dsrepair. Minimal and Network allow system startup with network connection. Dsrepair requires the system to enter the settings of the active directory from the backup device. Another option is Minimal (AlternateShell), which allows the system to call into the SHELL program specified by HKLM\System\CurrentControlSetSafeBoot\AlternateShell without using the default Explorer.
/NOGUIBOOT: The VGA driver is not loaded, and the blue screen information on startup and failure will not be displayed.
/BOOTLOG: Write logs to file.
/BASEVIDEO: Start using standard VGA mode, which is mainly used to display driver failure.
/SOS: It displays its name when calling in the driver name. It is better to use it when it cannot be started due to driver problems.
Through the above settings, we can easily set the startup menu!
From the above we can see that it is a very important system file. Without it, the system will not be able to boot. Therefore, in addition to making necessary backups, we also need to edit its methods. Especially when installing multiple systems, if the installation order from low to high (Windows 98, Windows 2000, Windows XP, Windows 2003) is not followed, the file will often be corrupted. If we master the methods of modifying and editing it, we will not have no choice.
Modify the Windows startup screen
1. Open c: with notepad, find the line where the Windows XP startup item is located, and add /noguiboot at the end
2. Find the boot screen you made and store it in c:\windows. Name it as the picture size is 640*480 16 colors.
