Common problems with XP and Win7 dual systems

First, repair Windows 98/XP dual system boot Menu

1. Before repairing, set boot from CD drive in BIOS. Start your computer with the Windows XP Setup disk, and after you load the necessary drivers, the installation interface for Windows XP appears. There are three options:

(1) To start installing Windows XP now, press the "enter" key.

(2) To repair the Windows XP installation with the Recovery Console, press the "R" key.

(3) To exit the installation program, do not install Windows XP, press "F3" key;

2. Press the "R" key to enter the "Microsoft Windows XP (TM) Recovery Console" interface; The Recovery Console provides system repair and recovery capabilities for the latest XP system downloads. The system then searches for installed Windows XP system files, displays the search results, and asks "which Windows XP installation (to cancel, press Enter) to log on to", select 1. D:windows, enter, the system will ask "Administrator password", and then type the administrator password that was set when Windows XP was installed, enter, d:windows〉, you need to enter the repair command fixboot, the following parameter is the boot sector to write the disk letter, here Fill in C: Enter. Repair complete, type exit to exit. After restarting, you will see a long-lost dual-boot menu. And, after this repair basically does not produce the garbage file.

Second, the ingenious repair windowsxp double Start Menu

A new installation of windowsxp under WINDOWS98 will automatically generate a dual-boot menu, which is quite handy. WindowsXP is an extremely stable operating system, but because the files in the dual-boot menu are generally in the C-packing directory, they are easily damaged. While you can back up files related to dual-boot, you can also use Ghost to back up the entire C drive, or make an emergency repair floppy disk to recover when it is damaged, but what if the user carelessly did not make a backup and did not have an emergency repair diskette? Do you want to reload windowsxp? There are dozens of size software?! In fact, we have one last move: Recovery Console.

Start and reload like, to choose a new installation, such as the installation files copy good, the computer restarts, choose to go to the Recovery Console, the console will prompt you to log in to which windowsxp installation, generally choose the default "1", type the system administrator password, you enter the console of the Windows directory, Type "Bootcfg/add", the console will scan the Windows installation, a few seconds after the scan is complete, prompted to select the installation to add, choose "1", and then prompt for the input load identifier, you can enter "Microsoftwindowsxpprofessional", Prompt for OS load options, type fastdetect, enter, type "EXIT", restart your computer, and you can see the familiar dual boot menu back again. After entering the system, delete all files and folders with "$" in all partitions.

Third, restore WINME/XP dual system boot Menu

Experience the charm of two Windows operating systems at the same time, with Windows Me and Windows XP dual boot, is a choice for many users. However, for various reasons, many times you may want to reload Windows Me. This reload doesn't matter, and you'll notice that the boot selection menu for the dual boot is gone (in the case of re-loading Windows 9x in DOS, especially after formatting the C drive)! So, where is Windows XP going?

There is a sequence of peaceful coexistence

In general, when installing a dual system, we install Windows Me First and then install Windows XP on another partition.

After installing Windows Me, the C-Drive zone stores the boot information for Windows Me, booting the system by loading the system files Io.sys and Command.com to boot Windows Me.

After installing Windows XP, the C-drive zone is covered by the boot information of Windows XP, and the boot information used to start Windows Me is moved outside the boot area and stored in a file named Bootsect.dos.

After dual booting, the system reads boot. ini by loading the Windows XP system file Ntldr, looks for other operating systems, and displays a boot selection menu that lets the user determine which system to start: If you choose to start Windows Me, The Io.sys and Command.com system files are loaded with Bootsect.dos to boot Windows Me, and if you choose to start Windows XP, you can directly load NTLDR, boot Windows by nntdetect.com system files Xp.

Different partitions are prerequisites

Once the Windows Me is installed again, the boot area of the C drive becomes the boot information for Windows Me again, even though the Ntldr and boot. ini two files still exist and the system does not load them at boot time, so the boot selection menu does not appear, and if you format the C drive, These two files will no longer exist, and will not appear on the Boot selection menu.

In fact, most users of Windows Me and Windows XP are not installed on the same partition, although the format of the C-disk, reinstall Windows Me, the change is only the C-drive boot area, choose to boot different systems of system files, and C-drive windows Install files and settings information for me. That is, the Windows XP installation files and settings stored in other partitions are not corrupted, so you can quickly restore Windows without having to re-install and setup Windows XP with a time-consuming effort, just restore the boot area of the C drive and select the system files for the boot system. Me and Windows XP dual boot, back to the original Windows xp!

To see the truth through the Mist

The ways to recover Windows Me and Windows XP dual boot are:

1. After you start Windows Me, perform the setup program for Windows XP.

2, according to the normal installation process, in the installation of the first step "installation Options" select "New Installation (Advanced)."

3. Enter the installation password, skip "Upgrade Drive" (Do not select "Upgrade to NTFS file system") and "Download updated installer files" two steps.

4, the system began to copy the installation files, and so on after the green copy progress bar to the end, the "Restart the computer" Red progress bar, at this time, quickly press the "ESC" key, prohibit the restart (successfully disable the restart is directly into the 7th step).

5. If the system restarts without pressing the "ESC" key in time, a boot selection menu will appear, including three startup options (after formatting the C drive, only the latter two appear):

Microsoft Windows XP Professional

Microsoft Windows Millennium Edition

Microsoft Windows XP Professional installation program

6. Press the keypad area arrow key to select "Microsoft Windows Millennium Edition" to start Windows Me within 5 seconds.

7, into the C disk can be seen, the root directory has been implemented to achieve the dual boot needs of the five files: "Ntldr", "Ntdetect.com", "Boot", "Bootfont.bin", "Bootsect.dos".

There are also three installation files for Windows XP "Ldr", "drvltr. ~_~", "Txtse-tup.sif" and One Folder "WIN_NT.~BT", and the other partitions each have a disk acceleration file "drvltr. ~_~", which can be deleted directly.

8. Modify the boot. ini file. In the [Boot Loader] Segment: "Default=c:win_nt.~btbootsect. DAT "line to" Default=c: "If you do not select from the Startup Selection menu, boot Windows Me from the C drive by default, or change to" Default=multi (0) disk (0) rdisk (0) partition (2) WINDOWS To enable the system to boot Windows XP from disk D by default (if Windows XP is installed on the E drive, change "2" in "Partition (2)" to "3", and so on).

At the same time, the [boot Loader] segment can be set to maintain the start selection menu (in seconds), the "timeout=5" in the "5" to the time you want to windows7 system download.

In the [Operating Systems] section, delete the c:win_nt.~btbootsect. dat= the "Microsoft Windows XP Professional Installer" line, you can screen out the installation options for Windows XP from the boot selection menu. If you reload WINDOWS Me after formatting the C drive, add "multi (0) disk (0) rdisk (0) partition (2) windows=" Microsoft Windows XP Professional "/ Fastdetect "line, which enables the system to boot Windows XP from disk D in a fast-start manner. You can also modify the text displayed in the Boot selection menu in the [Operating Systems] section, for example: Change Microsoft Windows XP Professional to "Windows XP Chinese", "Microsoft Windows Millennium Edition "Changes to" Windows Me Millennium ", and then the selection on the boot menu is" Windows XP Chinese "and" Windows Me Millennials ".

9. Reboot will restore dual boot, and all Windows XP settings remain the same, with no change before reinstalling Windows Me.

If you install a dual operating system friends will know that the general dual system will be 98/me plus 2000/xp such a type of operating system, when installing the operating system xp/2000 will automatically establish a dual system boot menu, The dual system is started because there are several files in the root directory of the C drive: Win.ini boot. ini bootfont.bin ntdetect.com ntldr Io.sys Msdos.sys After these two are to be changed in the Folder Options ( Hide protected system files) to see. Preferably in one of the system after a bad backup of these files, if there is no backup before the C-disk format, and installed the 98/me words is not feel there is no way to recover it? Here's an easy way to do this:

C:/=②: Windows me/98

Then reboot the system to discover that the dual boot menu has been restored.

Five, dual operating system coexistence frequently asked questions

Installation sequence for dual systems

Q: I'm going to install multiple systems (Windows 9X/XP) on a single computer, what's the priority in the sequencing of the installation? What should I pay attention to?

A: In general, the installation sequence is the first low-level version to the advanced version, that is, first install windows9x, and then install the WindowsXP under the WINDOWS9X system, the advantage is that the system can automatically generate the power-on selection screen.

The following points to note:

1, to install each system in a different partition. The best arrangement is to install Windows 9x on the C drive and Windows XP on the D drive.

2, for different systems to choose a different system file format. For windows9x, choose FAT16 or FAT32, and for Windows XP, it is best to use NTFS format so that the system has the potential to perform better.

3. When installing Windows XP on Windows9x, select "New Installation" and do not select "Upgrade Installation".

How to install a low version of a high version

Q: My system is Windows XP, and now I want to install another Windows 98, how do I install Windows 98 with a dual system while retaining Windows XP?
