Windows XP and Windows 7 dual-system ghostxp cannot be used after Windows XP is reinstalled or a simple solution

Instance:

My classmate's computer had only one XP system on the C: disk, and then I installed a win7 flagship edition on the D: disk for her.

One day, in order to learn how to use ghostxp to reinstall the system, she reloaded the C: disk.

The result is that there is no win7 in the startup item, and only two of them are available: Microsoft Windows XP Professional + 小.

 

Solution

Step 1:Download a "config Item Repair Tool" or easybcd to fix the startup item under XP, and then restart.

Then there should be two options in the startup item, one being Windows 7 and the other being earlier windows (or early version of Windows .)

Select Windows 7 from Windows 7. Is it normal? If it is not normal, it is necessary to activate it again, but it cannot go to the table again, explore.exe cannot run, there are DLL errors such as mscories. dll or iedkcs32.dll lost entries, then go to step 2.

 

Step 2:Press CTRL + ALT + DEL to start the task manager. On the Application tab, click "new task", Enter cmd in the open window, and press ENTER or OK.

A black Command Prompt window pops up to check whether the path of the row where the flashing cursor is located is C:/Windows/system32>. It should have been on the D: disk!

Then we use the Registry Editor to change it back. Choose Task Manager> new task, enter Regedit (if you are not sure or use administrator permissions, you can fully check the Regedit), and then confirm. In the Registry Editor, find mounteddevices under system under HKEY_LOCAL_MACHINE, click it, and drag the scroll bar on the right down. Do you see many/dosdevices/+ drive letters under it? We need to rename C: To D: (do not change the drive letter) but there cannot be two identical drive letters at the same time: change to Z: (change to any unused drive letter), then change C: To D:, and then change D: To C :( C: And D: ). Restart. Success! If you need to activate it, download another activator ~
