Solution to the Problem of Linux system deletion and Windows Startup failure in a dual-System Environment

I installed a linux and deleted it directly later. As a result, the computer cannot be restarted when it is restarted. grub always appears when it is turned on, and grub is so angry that I cannot figure it out later, I plan to directly reinstall the system. As a result, I encountered a problem in the process of reinstalling the system. The BIOS was set to a password, which was useless for a long time. If I forgot it, it would be terrible. Wouldn't this computer be scrapped, after checking various information on the Internet, I found a good solution to solve the problem of BIOS password (however, this method is very useful for desktops and the notebook is troublesome ).

Major trick 1: CMOS discharge

Big trick 2: win-guided repair

Although the BIOS password is fixed, there are still problems. You can use the PE tool hard disk to start the Windows system or use the command mode to enter

However, these methods cannot solve the problem I want to solve, but fortunately, I finally found a more appropriate method, that is

After entering the win7PE system, click [windows boot repair] on the desktop, enter 1, Select Automatic repair, and the system will automatically repair the boot!

In this way, the problem is solved.
