Use PE system to repair MBR

Configuration:System: win7 + Ubuntu dual-System Computer: Sony

Cause:

After windows 12.04 and Ubuntu are installed, Ubuntu has some problems, so I want to reinstall ubuntu.

I used the easybcd software to install the dual-system, because I did not know about the software and system, and so on. I just thought about it. Do I think Sony has any built-in recovery software? I can fix the entire hard disk and restore the system to the factory status. So I did it.

As a result, there is a tragedy: the boot immediately appears

 
Error: no such partitongurb> Rescue
 

I don't know what to do!

 

Solution Process:

First, Google down what grub is, and then find related commands. No good solution

No more

Later, I found a lot of relevant information and found that many netizens mentioned how to use the PE system to repair MBR. This method may be feasible!

So I used a USB flash drive, backed up the data, and formatted it. Download the "Cabbage super USB flash drive preparation tool" (this tool can install a PE System in the USB flash drive), about MB

First, insert a USB flash drive.

Then set the BIOS startup sequence.

Start the instance and press F2 (SONY laptop enters BIOS in this way)Different laptops use different methods for entering the BIOS. refer to an article in Baidu Library.Article Http://wenku.baidu.com/view/5d5ff422bcd126fff7050bd5.html

First, set external device Boot of boot configuration to enable

Then, set external device to the first item in Boot priority and internal hard disk drive to the last item.

In this way, select the win7 PE system. SelectDiskgenius (that is, the previousDiskman ). Open the software, title bar --- hard disk ---- rebuilding the Master Boot Record (MBR ). In this way, the MBR is fixed.

Start the instance again, press F2, enter bios, and restore all settings to the default parameters (this restore option can be found on the exit tab)

The problem is solved, and the system is restored to the factory status!
