Windows Boot Manager means boot manager, that is, the computer cannot be normal after power-on The boot is turned on and needs to be set. There are some reasons for this prompt when booting up, such as damaged disk master boot, damaged system boot file, damaged disk, etc.
What is GRUB GNU GRUB is a multi-operating system startup manager. GNU GRUB is derived from GRUB (GRand Unified Bootloader).
The startup file is on one disk, while the operating system file is on another disk: this means that the boot manager is stored on the startup disk, but the actual Windows operating system file is on another disk.
GNU GRUB and GRUB are the abbreviations of GRand Unified Bootloader, which is a multi-operating system boot manager. It is used to boot different systems, such as Windows and Linux.
GNU GRUB (GRand Unified Bootloader abbreviated as "GRUB") is a multi-operating system launcher from the GNU project. GRUB is an implementation of the multi-boot specification, which allows users to have multiple operating systems in the computer at the same time and select the operating system they want to run when the computer starts.
The role of the boot drive is the drive where the boot record and the boot program are located. After use, the BIOS startup will look for the system boot file in the order of settings. Computers are a must-have equipment for every family nowadays. The diversity of computer functions can no longer be summarized in one or two sentences.
1. EFI startup is similar to GRUB startup. EFIShell can be called at startup, where you can load the specified hardware driver and select the boot file. For example, the default startup fails, and the boot file on the USB disk is loaded in EFIShell to continue to start the system.
2. The task of detecting hardware functions and booting the operating system. UEFI is a concept opposite to BIOS. This interface is used to automatically load the operating system from the pre-started operating environment to an operating system, so as to achieve the purpose of simplifying startup programming and saving time.
3. UEFI startup is a new motherboard boot item, which is a new annotation setting for motherboard boot initialization.Advantages of uefi startup compared with Bios startup: more security. UEFI startup requires a separate partition to isolate the system startup file from the operating system itself, which can better protect the startup of the system.
4. UEFI boot is a new motherboard boot item, which is regarded as the successor of the BIOS with a history of nearly 20 years. Its advantage is that it can improve the startup speed of the computer and enter the operating system after it is turned on.
5. Switch to the Startup tab. As shown in the figure below, CSM (CompatibilitysupportModule) represents a compatibility module. This option is specially set up for compatible devices that can only work in legacy mode and operating systems that do not support or cannot fully support UEFI.
boot partition. According to the official website of the CSDN blog, the boot drive needs to select the boot partition, and the installation drive needs to select the c disk. In a broad sense, the driver refers to the driver hardware that drives a certain type of device, which can actually be installed by professionals during installation.
There is no rigid regulation for installing the system to select the partition (disk character), and usually the first partition (C: disk) is selected. This is just a habit. It is recommended that you also use the C partition to install the system, so that it will be more convenient for system maintenance and installation of other applications later.
The way to write hereThe default is USB-HDD+, and I also chose it, but some people say that USB-ZIP+ should be chosen. I don't know the specifics, but I can install it successfully according to my choice.
The method of repairing the boot file of the win10 system: In the left search bar of the start key in the lower left corner of win10, enter the cmd command line mode, as shown in the figure below. Enter sfc/scannow, the command must be executed as an administrator, otherwise the operation will report an error, as shown in the following figure.
To repair the system boot file, you need to make a system boot USB flash drive or Win PE USB flash drive. Step 1: Use the made system to start the USB disk or Win PE USB disk and enter the [command indicator]. Note: The operation screen may be different for different operation methods.
Method/Steps If you don't want to reinstall Win10, you can only use EasyBCD to repair the system boot items. Download the EasyBCD 3v software first, then install it, open it, enter the main program interface, and select "Advanced Settings" in the options on the left.
Right-click on the start menu, open the command prompt (administrator) and enter the netsh winsock reset catalog prompt to restart the operating system after success.Note: Other ways to enter the safe mode of win10: you can enter the system. Press and hold shift (up key) and click to restart the computer.
Download the Xiaobai one-click reinstall tool to make a boot disk, insert the USB disk into the computer, press the F12 startup hotkey continuously, and select the USB disk to start. Then select the first start. After entering pe, we open the boot repair tool. Determine the partition of our boot file.
chkdsk /r After the disk check is completed, you can try to restart the computer to see if the problem is solved.
