[0060] The embodiments of the present invention provide a pre-installation environment image installation method, device, equipment and storage medium, which are used to solve the technical problem that formatting partition errors and editing errors may occur during manual operation and the efficiency is low.

[0061] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0062] See also Figure 1 , Figure 1 A flowchart of the steps of a pre-installation environment image installation method provided by an embodiment of the present invention.

[0063] The present invention provides a method for installing a pre-installation environment image, which may specifically include the following steps:

[0064] Step 101, obtaining the pre-installation environment boot medium and the installation image source file;

[0065] Preinstallation Environment, or WinPE, is a minimal Win32 subsystem with limited services, based on the Windows 3.x and above kernel running in full Windows environment or protected mode. Such systems are generally small. It includes the minimum functionality required to run Windows installation programs and scripts, connect to network shares, automate basic processes, and perform hardware verification.

[0066] In the embodiment of the present invention, the absolute paths of the pre-installation environment startup medium and the installation image source file may be searched, and the pre-installation environment startup medium and the installation image source file may be acquired from the absolute paths.

[0067] In the specific implementation, after obtaining the absolute path, first determine whether the absolute path contains the pre-installation environment boot medium and the installation image source file. If the file does not exist, the program terminates and prompts an error message; if the file exists, proceed to step 102.

[0068] Step 102, calculating the file sizes of the pre-installation environment boot medium and the installation image source file, and determining the target mobile disk according to the file sizes;

[0069] When the pre-installation environment startup medium and the installation image source file are found in the absolute path, the file sizes of the pre-installation environment startup medium and the installation image source file are calculated, and the user is prompted to select a target mobile disk with a suitable capacity to insert into the device.

[0070] Step 103, formatting the target mobile disk into different target partitions;

[0071] In the embodiment of the present invention, disk.exe can be used to format the target mobile disk into different target partitions, such as partition A of FAT32 and partition B of NTFS.

[0072] Step 104, copying the pre-installation environment boot medium and the installation image source file to the corresponding target partition;

[0073] After completing the formatting partition of the target mobile disk and verifying that the formatting partition is successful, you can copy the pre-installation environment boot media and the installation image source file to the corresponding target partition.

[0074] In an example, the pre-installation environment boot medium may be copied to the root directory of the A partition, and the installation image source file may be copied to the root directory of the B partition.

[0075] Step 105, verifying the target partition, and when the verification passes, obtaining the file format type from the installation image source file;

[0076] Step 106, compile a script of the pre-installation environment boot medium according to the file format type;

[0077] In the embodiment of the present invention, it can be determined whether the pre-installation environment boot medium and the installation image source file are successfully copied to the target partition. If the copy is successful, the file format type can be obtained from the installation image source file to compile the script of the pre-installation environment boot medium according to the file format type.

[0078] Step 107: Use a script to perform mirror installation on the target device.

[0079] In the embodiment of the present invention, after the script of the pre-installation environment startup medium is compiled, the script can be used to perform mirror installation on the target device.

[0080] The present invention reduces errors caused by manual operation of formatting partitions by automatically formatting partitions after screening the target mobile disk and by detecting whether the pre-installation environment startup medium and the installation image source file are successfully copied to the target partition; the present invention also compiles the script of the pre-installation environment startup medium according to the file format type in the installation image source file, thereby improving the compilation success rate and improving the efficiency of pre-installation environment image installation.

[0081] See also Figure 2 , Figure 2 A flowchart of a method for installing a pre-installation environment image is provided in another embodiment of the present invention. Specifically, the following steps may be included:

[0082] Step 201, obtaining the pre-installation environment boot medium and the installation image source file;

[0083] Step 202, calculating the file sizes of the pre-installation environment boot medium and the installation image source file, and determining the target mobile disk according to the file sizes;

[0084] Steps 201-202 are the same as steps 101-102. For details, please refer to the description of steps 101-102, which will not be repeated here.

[0085] Step 203, formatting the target mobile disk into different partitions and generating drive letters for each partition;

[0086] Step 204, judging whether the partition is created successfully according to the drive letter;

[0087] Step 205, if not, return to the step of formatting the target mobile disk into different partitions;

[0088] Step 206, if yes, output the partition as the target partition;

[0089] In one example, if Figure 3As shown in the figure, after the target mobile disk is inserted, it can automatically identify the inserted target mobile disk and mark the disk number, and then use Disk.exe to format the marked disk into FAT32 and NTFS. The program will mark the drive letters of the two target partitions respectively and detect whether the two partitions are successfully created; if the detection fails, it will try to format the partition again and set the upper limit of the number of retries (such as three times); if the three retries are still unsuccessful, an error will be reported through the disk partition unit and the program will be terminated.

[0090] Step 207, copying the pre-installation environment boot medium and the installation image source file to the corresponding target partition;

[0091] Step 208, calculating the hash value of the target partition, and when the hash value meets the preset condition, obtaining the file format type from the installation image source file;

[0092] In the embodiment of the present invention, after completing the formatting partition of the target mobile disk and verifying that the formatting partition is successful, the pre-installation environment boot medium and the installation image source file can be copied to the corresponding target partition. And the hash value is used to determine whether the pre-installation environment boot medium and the installation image source file are successfully copied to the target partition.

[0093] In one example, step 208 may include the following sub-steps:

[0094] S81, calculating a first hash value of a file in a target partition corresponding to the pre-installation environment boot medium;

[0095] S82, calculating a second hash value of a file in the target partition corresponding to the installation image source file;

[0096] S83, obtaining a third hash value of the pre-installation environment boot medium;

[0097] S84, obtaining a fourth hash value of the installation image source file;

[0098] S85, determining whether the first Hash value is the same as the third Hash value, or whether the second Hash value is the same as the fourth Hash value;

[0099] S86, if different, return to the step of copying the pre-installation environment boot medium and the installation image source file to the corresponding target partition;

[0100] In the specific implementation, Figure 3As shown, after the pre-installation environment boot medium and the installation image source file are copied to the corresponding target partition, the first hash value of the file in the target partition corresponding to the pre-installation environment boot medium and the second hash value of the file in the target partition corresponding to the installation image source file can be calculated; and the first hash value is compared with the third hash value of the corresponding pre-installation environment boot medium, and the second hash value is compared with the fourth hash value of the corresponding installation image source file. When both are the same, the representation file is copied correctly, and the copy process ends at this time and enters the next link. When either of the two is different, the representation file is copied incompletely and needs to be copied again; in order to avoid continuous repeated copying, the number of retries can be set, and the number of retries can be judged at each retry; when the number of retries is within the preset number, a retry is performed, and when the number of retries exceeds the preset number, an error is reported and the program ends.

[0101] S87, if they are the same, updating the driver of the pre-installation environment boot medium;

[0102] In actual scenarios, before entering the WinPE environment, a terminal (such as a computer) sometimes needs to add necessary drivers to the pre-installation environment boot media to enable certain functions. Therefore, when making WinPE, you need to add the required loaded drivers to the specified folder.

[0103] In one example, step S87 may include the following sub-steps:

[0104] S871, checking whether the preset designated folder is empty;

[0105] S872: If yes, it is determined that the pre-installation environment boot medium does not need to add a driver;

[0106] S873: If not, load the driver in the pre-installation environment startup medium.

[0107] In the specific implementation, Figure 4 As shown, first check whether the specified folder is empty; if the file is empty, the program automatically determines that no driver needs to be added; if the folder is not empty, traverse and install the drivers one by one. After the installation is complete, record the installed drivers and check whether these drivers already exist in the WinPE boot image. If the driver already exists, the module ends. If the driver does not exist, it is judged that the detection failed and the driver is reloaded until the maximum number of retries is reached. If the number of retries is exhausted and still unsuccessful, an error message is thrown and the relevant program is terminated.

[0108] S88, when the driver update is completed, the file format type is obtained from the installation image source file.

[0109] When the driver update is completed, the file format type can be obtained from the installation image source file to compile a script of the pre-installation environment startup medium according to the file format type.

[0110] Step 209, compile the script of the pre-installation environment boot medium according to the file format type;

[0111] like Figure 5 As shown, the file format may include WIM, FUU and others. If the file format type is detected to be WIM or FUU, the corresponding installation script is compiled according to the corresponding type; if it is detected not to be WIM or FUU, it is determined to be unsupported and the process ends.

[0112] Step 210: Use a script to perform mirror installation on the target device.

[0113] The present invention reduces errors caused by manual operation of formatting partitions by automatically formatting partitions after screening the target mobile disk and by detecting whether the pre-installation environment startup medium and the installation image source file are successfully copied to the target partition; the present invention also compiles the script of the pre-installation environment startup medium according to the file format type in the installation image source file, thereby improving the compilation success rate and improving the efficiency of pre-installation environment image installation.
