How to delete GRUB boot information?

3li Q: I tried GRUB to boot the Win7 system before, and then the activation failed. Is there any way to delete the GRUB boot program separately, and directly use the boot program that comes with Win7.

Unfortunately, the best answer you have chosen in learning is wrong. GRUB is not undelete, but it is very good. You can use a special bootloader to remove GRUB, and even Windows 7 itself can do it yourself. The core method is to use the bootsect /nt60 all command, this command can be completed under Windows7, as follows: Open the Start menu → All Programs → Accessories → Right click on the "Command Prompt" and select "Run as Administrator" , then enter the above command in the command prompt window.

If you have accidentally deleted GRUB and you are unable to enter Windows7, then you don't have to worry about booting from the Windows 7 installation CD. In the initial interface, select "Repair Computer" and select Repair Boot. If you don't have a bootable CD, you can also use Disk Genius 3.2 to fix it under PE.
