What should we do without DOS?
Author: .com.cn
Previously used Windows 98 era, if you encounter a system crash or other reasons could not enter Windows, we generally start using the boot disk to DOS down to troubleshoot errors. But now most people use Windows 2000 / XP, not only these operating systems themselves and DOS is not compatible, and because the NTFS partitions may be used, they have not started with the DOS boot disk to enter DOS. So how do we fix these operating systems? In fact, Microsoft has thought of us, that is, the recovery console, in order to narrative, we will call it a console in the following, all in the Windows XP Professional Edition as an example (in fact this and The operation in Windows 2000 does not differ much). What is the console console is a simple running mode of Windows, which may not activate the graphical interface and have restricted FAT and NTFS partitions in the command line state, and some settings and operations are made. Through the console, we can replace the system file, turn off or disable a system service, disable or uninstall the hardware device, repair the boot sector, new partition, and format hard disk partitions. How to start the console For Windows 2000, we can start your computer with an CD, then press the R key in the installer's menu, then press the Windows 2000 Installation, then press the C button from the repair menu to repair Windows 2000 ". For Windows XP, the computer is also powered on the CD, then press R to select the repair, you can enter the console directly. If you often go to the console, then every time the CD start system seems to have trouble, you can also directly install the relevant options of the console into the boot menu, the method is this: put the disc in the CD drive, then Enter "D: / I386 / WINNT32 / CMDCONS" Enter "D: / I386 / WinNT32 / CMDCONS" Enter "D: You can see the interface of Figure 1, click" Yes "to install the console option to In the advanced launch menu, you can enter the console directly from your hard drive. This method is suitable for Windows 2000 and Windows XP.
It should be noted that the console needs to be aware that you can only "limited" to access the hard drive under the console due to safety. "Limited" means that you can only access root folders, Windows system folders, detachable storage media (eg, optical drives, floppy drives). And in the console environment, you can only copy the file from the floppy disk or disc, and you cannot copy the files on the hard disk to the floppy disk or disc. The limitations mentioned above are not dead. If you are not strict on security requirements, and you need to copy files on your hard disk, you can also reset it through Group Policy (note that Windows XP Home Edition has no Group Policy) . Enter "gpedit.msc" in the run and enter the Group Policy Editor. Then in "Computer Configuration -Windows Settings - Security Settings - Local Policy - Security Options" Fault Recovery Console: Allows Panish Copy and Access to all drives and folders ", double click, and then enable it. This will copy the file from the console in this way.
After the previous operation, I have put the console in the startup option, so that after starting the computer, you can see the interface of Figure II (if it is Windows 2000, then press F8, then enter in the Advanced Launch menu), we pass the arrow Select to enter the console, then see the interface of Figure 4, where the installed operating system is displayed, select one of you wants to enter, press the appropriate number, and then enter. Here you also need to enter the administrator's password. When "C: / Windows>" appears on the screen, "C: / Windows>" prompts that have been successfully entered into the console.
If you are unfamiliar with the console, you can list all available commands at any time as long as you enter "Help" and enter. And if you have to understand the specific use of a command, you can enter the "HELP command" and then enter the car. Below we will explain the use of the console by demonstration of several most commonly used commands. Repair Double Windows System Recovery If you have installed Windows 2000 on your computer that has already installed Windows XP, you will make Windows XP will not start normally. This is because the boot file that can boot Windows XP is overwritten by the low version of the Windows 2000. To fix Windows XP, you must fix the replaced boot file. The boot files we need to repair have two: NTLDR and NTDETECT.COM, both files are saved under the I386 folder of the Windows XP CD. So we can repair the copy command in the console (here you assume that the optical drive is D, you can adjust according to your own actual situation): Copy D: / i386 / NTLDR C: Copy D: /i386/ntdetect.com C: Enter the above Command, press Enter to each line, so you can fix Dual startup of Windows XP and Windows 2000. Windows and Linux dual system recovery If you have already installed Windows and Linux dual systems, you may have a problem after you uninstall Linux, you will make you choose to start with DOS after you start your computer. Starting with DOS or starts with Windows. Although you have formatted Linux partition, this option may always exist. In this case, you need to use the fixmbr this command. Enter "fixmbr" in the console and enter the carriage return, the system will display some precautions and want you to determine, don't pay attention to those things, enter "Y" directly, press Enter, if the repair is successful, then the corresponding prompt is displayed in the command line. In this way, it will not let you choose whether to start Linux when startup. Although the partition and formatting operations of the hard disk can be re-partitioned or formatted by the management tool in Windows, it may have encountered a burst that you must complete them in the console. Then, the format and diskpart commands played. First we tried to partition the hard drive with DiskPart. Note that the "hard disk" here refers only to the unused hard disk space, if you want to restrict the Windows system disk, it is impossible to implement in the console. It is rare that the diskpart command has a simple graphical interface so that we don't have to remember those complex parameters, and more don't have to worry about a parameter to make an error data loss. Enter "DiskPart" in the console and enter the interface of Figure 5. Is it very familiar? Selecting the interface when installing Windows XP is like this. Press the arrow to select the unparalleled space, then press the "C" button to start a new partition, and enter the partition size you want to build, and a partition is created after the carriage return. However, the partitioned partitioning directly cannot be used because it is not formatted. So we also use the format command to format new partitions.
