Scope of application:
g40-70,g50-70 Lenovo small New notebook sr1000,linux change Win7
Knowledge Point Analysis:
This is for Windows 8 to Windows 7, but because Ghost and PE are used frequently, you need to change the GPT to MBR first, which may cause the hard drive to be unrecognized.
Operation Steps:
Note: Because the computer factory used hard disk is GPT partition format, so if you use Ghost and PE, is not recognized to the hard disk, this is normal, replace the installation version can.
Note Before you modify: If you are sure that you want to retrofit your laptop's preinstalled Linux system into a Windows 7 system, be aware of the following important points:
because your notebook is preinstalled with Linux systems, but the notebooks are set up in the Windows 8 system, so if you need to install a Windows 8 system, then after you have backed up the important data directly, you will be able to install the Windows 8 system. However, if you need to install a Windows 7 system, the UEFI features and GPT partition tables in the BIOS need to be changed, so when you retrofit your system to a Windows 7 system, you need to remove all partitions of the random Linux system. Because these partitions are created under the GPT partition table, Windows 7 uses an MBR partitioned table, which is incompatible with each other. So you will not be able to install your notebook in the installation of other systems. So please back up your laptop pre-installed Linux system for Windows 7 system before the operation of all the important data in your laptop hard disk backup to the mobile storage media (such as: USB flash drive, mobile hard disk, etc.). In order to ensure the smooth installation of the system, we strongly recommend that you use the genuine Windows 7 operating system CD (if your notebook does not have an optical drive, we strongly recommend that you use a USB optical drive to complete the operation).
