How to restore Windows 7 and Windows XP dual boot menus

  
        I often see people on the Internet asking questions about the dual system boot menu. In Baidu, I can also find a lot of solutions, but they are all the same, and there are very few articles that can really solve them. What I want to say is that this piece of repairing is the problem I encountered and the solution. It is not necessarily applicable to others. I only want to give you a reference and one more solution.

first talk about the specific issues I encountered:

I first installed in the C drive windowsxp, and then installed windows7 in the D drive. This is all normal, because I originally backed up the xp system, so I used a key to restore the C drive to restore, but the problem will come out, in the system startup items, only windowsxp and one key restore two options, There is no way to enter the windows7 system, because I have not touched windowsvisit, directly from xp to windows7, so I don't know much about its startup principle, so I studied the problem in one afternoon, and also learned the startup principle of Windows7 system. .

solve the problem before we start to look at windowsxp start and Windows7 What is the difference principle, the dual system and how to start:

in windows7 + xp dual system, Windows7 use bootmgr takeover System startup mode. After the computer self-test is complete, start looking for the active primary partition (generally C:) and load it.

will then continue to read the startup configuration file (ie C: BOOTBCD) under the active partition and c:? Oot.ini, listed according to the boot menu and BCD Boot.ini startup information stored (ie double System boot menu). For dual system users, "Microsoft Windows 7" and "old version of Windows" are usually listed.

If you choose the former, Bootmgr control to the Winload.exe under windows7 system directory (under windowssystems) and then started Windows7. Select the latter, Bootmgr gives control to NTLDR, then starts reading c:?oot.ini and lists the boot menus configured in it.

start on the main fault occurs in Bootmgr (if the file is missing), BCD (boot configuration error message), Winload.exe (the file is lost cause Vista can not start), Ntldr (the file is missing resulting in XP does not start ) These files are on. (In my case belong bootmgr file is missing, BCD file to start the configuration error information) big test - the country's largest educational website ( www.Examda
.com)

Let's solve the problem: < BR>
First we need several backup files (bootmgr, ntldt, bcd, bootsect), if you have a Windows7 system disk or image, you can extract directly from it.

there is a tool --EasyBCD

Note: You need to support Microsoft.NetFramework2.0 in EasyBCD run under XP, go to http://msdn2.microsoft.com /zh-cn/vstudio/default.ASPx
Download and install.

the following operations are carried out in WindowsXP, because he was hidden and system files, so the best display system and hidden files, click Folder view option, remove the hidden protected system files (Recommended) And choose to choose to display the files and folders. The

(with, in general without copying the C drive) bootmgr, ntldt copied to the C drive. (This is the default for the C drive system, as the case may be)

the bcd, bootsect copied to the C:? Under oot directory

then switch to run EasyBCD

On the left side of the "ADD/RemoveEntrIEs", select the original invalid boot menu in the right pane, click Delete to delete, and then add the startup item under AddAnEntry. To add XP, select "WindowsNT/200/XP" in Version, C: in Drive, and Windows XP in Figure (Figure 3). Same as above, add the startup item of windows7 (Version selects WindowsVista/longhom, Drive selects D:, Name is set to Windows7), and clicks ADDEntry to save the configuration after completion.

then open the "Run" (Start> Run), type cmd

into the C:? Enter oot directory under "bootsect /nt60C:" (delete is nt52, without the quotation marks) < BR>
last restart problem

everyone you meet with me might be different, according to their own circumstances specific solutions, more than just a reference, I find this information found on the internet is not a lot, There are a lot of changes to boot.ini, some can not solve the problem, and some are particularly troublesome. Think more about having problems, mostly look for information online, always solve the problem.
