Is this skill very high-minded? Go and share it! Please indicate: System Home
Computer equipment hardware keeps falling with the price“Master machine” Finally, it has revived the glory through the upgrade. Run on a dual system (Windows XP and Windows 2000). Since the computer is placed in the dormitory, it naturally becomes a "public product", but there are many settings in the Windows 2000 system that do not want others to see it. What should I do? I can't set a password! I think about it, finally I thought of it. A great way, the author will introduce it below.
First of all, find the boot information file (Boot.ini), because it is hidden, we can choose "Resource Manager", select the "Tools" menu in the "folder options", in “View ” uncheck the "Hide Protected System Files" checkbox in the “ option, and tick "Show all files and folders" in “Hide files and folders> frame. This removes the hidden attribute, you can see the Boot.ini file in the C drive.
[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" /fastdetect
c:\\="Windows 2000"
The following is a brief description, timeout=30 refers to the boot When the menu is selected, the time taken to enter the default operating system when the user does not perform any operation after the boot menu is started. The default setting is 30 seconds, which can be changed at will. If it is changed to 0, then the selection will not appear. Menu, go directly to the default system (here is Windows XP), if I don't want others to enter my Windows 2000 system, then modify the Boot.ini file to achieve. First set the timeout to 2 seconds, then delete the Windows 2000 after the last line of the equal sign. When starting up, others will only see Windows XP and one line. Windows 2000 actually has it, just can't see it. Who can think that at this time, just press the down cursor button to enter 2000? Because the waiting time is only set to a short two seconds! In a blink of an eye, the system directly enters Windows XP.
