What should I do if the grub system starts up with grub?

Recently, users found that they could not be turned on when they started the Win7 system computer, and a grub prompt appeared. After the query, the reason for this problem was that the main boot was lost. Now that we know the problem, then let's take a look at how to solve this problem.

Note: Before proceeding, also you need to prepare a U disk boot disk.

grub Definition:

gnu grub and grub are short for GRand Unified Bootloader, 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 operating systems. It should be said to be the mainstream.

Windows also has a similar tool NTLOADER; for example, after we installed Windows 98 in the machine, we installed a Windows XP, there will be a menu in 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 the PowerPC architecture machine, if the Powerpc version of Linux is installed, 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 version, mostly using 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.

Some can appear by pressing the Enter key to select the startup method.

If this can not start or it can be solved using the following methods:

1. /U disk is started by the optical disc, to resolve to repair the master boot;

2. Start the USB flash drive/disc and re-do a system;

3. Press the F5 key to enter the menu to repair the main boot. (This is because some WIN7GHOST systems, ome7f7 activation, others have not tried.)

After entering this interface, select the first item. Will enter the system, but the system is not activated, need to be reactivated, can be activated with a higher activation software.

Precautions

The premise mentioned above 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.

The above is to solve the grub method when the computer starts up. If the user encounters this problem during the boot process, you can use the above method to solve it.
