Grub's handling coup after Win7 startup

Many users often lose some boot files of the system when they uninstall the software, which makes it impossible to boot. Especially the Winb system has Grub problems when it starts up, because the important boot files are gone. To solve this method, we also need to understand the definition of Grub.

grub defined:

GNU GRUB and GRUB is the GRand Unified Bootloader abbreviation, it is a multi-OS boot manager. Used to boot different systems, such as windows, linux.

In the X86 architecture machine, GRUB and LILO are the most commonly used in Linux, BSD or other Unix-like operating systems. It should be said to be the mainstream.

Windows also has a similar tool NTLOADER; for example, after we installed Windows 98 on the machine, we installed a Windows XP, there will be a menu on the machine boot, let us choose whether to enter Windows 98 or enter Windows. XP. NTLOADER is a multi-system boot boot manager, NTLOADER can also boot Linux, but it is extremely troublesome.

In PowerPC-based machines, if you install the Powerpc version of Linux, most of them use the yaboot multi-boot manager. For example, the Apple machine uses the IBM PowerPC processor, so if you want to install Macos on the Apple machine, And Linux Powerpc versions, mostly use yaboot to boot multiple operating systems.

Because X86-based machines are still mainstream, GRUB and LILO are still the most commonly used multi-OS boot managers.

Solution:

First, some can appear by pressing the Enter key to select the startup test.

Second, if this still does not start, then you can lead a way to resolve the following:

1. /CD started by U disk to repair the master boot to solve

2. Boot through the USB flash drive /CD boot, re-do a system

3. Press the F5 key to enter the menu to repair the main boot. (This is because some WIN7GHOST system, ome7f7 activated, the other not tried.) Select the first item after

Use this menu. Will enter the system, but the system is not activated. Reactivation is required and can be activated with a higher activation software.

The precondition for the above method is that the hard disk you set in the BIOS of the motherboard is the first boot entry. Then select your current hard drive in BOOT. Normally, setting the hard disk as the first boot item can solve the problem. If it still doesn't work, the boot file is lost. Do the above or directly reinstall the system. Sometimes it is faster and more convenient.
