Thinkpad win8 replaced by win7 system

        Foreword: Recently bought a thinkpad notebook from the Internet, pre-installed win8 system, the user experience of win8 system is still good, but it is not enough for our programmers, such as not using a virtual machine, not properly configured, etc. . I feel that win8 compatibility may not be enough, so I want to change to win7, so I will toss it up. I used to install the system with u disk, but I can't install it this time. The reason is that the disk format is gpt. It is not the commonly used mbr (now the computer is advanced, I have never considered this situation before), so I can't use ghost. ! How to solve it? It is to erase all partitions, convert the disk format to mbr format, and then install the system properly! (My original idea is to install win7 to other disks, after all, win8 user experience is good!) The following is the conversion step, transferred from Lenovo official website: knowledge point analysis: random pre-installed Win8 computer, disk is GPT format, if you need to install Earlier versions of Win7 and other systems need to be converted to MBR format. The Diskpart command can be used to complete the conversion. Steps: Note: Converting the disk format requires clearing all partitions and data on the disk. Before operation, save all important data on the disk. 1. Use Win7 CD or U disk to boot, enter the system installation interface. 2. Press Shift + F10 to open a command prompt. 3. Enter “Diskpart” (without entering quotes, the same below), and press Enter to enter the operation interface 4. Enter: “list disk”, view the disk information. Pay attention to the disk capacity to choose. In the figure, Disk 0 of 465G is a hard disk, and Disk 1 of 3852M is a USB disk for Win7 installation. 5. Enter: “select disk 0”, select disk 0 for the currently operating disk 6. Enter: ”Clean”, clear the current disk partition. 7. Enter: "convert mbr”, convert to MBR partition. 8. After the operation is completed, close the command prompt window and continue to install the Win7 system in the normal way. Extended knowledge: Other uses of the convert command: convert basic - converts a disk from dynamic to basic. Convert dynamic - Converts a disk from basic to dynamic. Convert gpt - Converts a disk from MBR to GPT. Convert mbr - Converts a disk from GPT to MBR.
