Change Sony VAIO laptop Windows 8 to Windows 7 my model: eseries SVE14A. 1. Windows 8 has been installed for this series of models at the time of purchase. To install Windows 7, you must format all the hard disks and repartition them. First, copy the useful data using a USB flash drive. If you still have a crush on Windows 8, please use it for a while, because you will never see the annoying Windows 8 again in the next step. 2. Shut down. Press the Assist key. 3. the BIOS option is displayed on the screen. Press enter. 4. Find the Boot Mode item, which was originally UEFI and changed it to Legacy. 5. Under the same screen, select start from the CD. (Optical Disk) 6. put the Windows 7 installation disk into the optical drive, 32-bit or 64-bit can be, must be a pure version of the installation disk, that is, step by step installation, the CD only Win 7, without any additional software. It cannot be a ghostversion, a quick installation version, a garden, or a clone version. 7. Press F4 on the BIOS screen and press Enter. (Save and restart) 8. Normally, you can enter the Windows 7 installation screen. If there is a problem with this step or any of the following steps, you can either try again several times (I just try again several times), or change to a Win 7 installation disk and try again. 9. On the Windows 7 installation screen, when selecting hard disk partition, no matter which partition you choose, "Windows cannot be installed on this disk. The selected disk adopts the GPT partition format "error. 10. Press Shift + F10 on the screen. A black DOS command window is displayed. 11. Enter Diskpart and press Enter. Wait a few seconds, wait for Diskpart to start, and the cursor appears. 12. Enter the following commands. Press ENTER for each line. List disk select disk 0 clean convert mbr create partition primary size = 40000 format fs = ntfs quick exit note: 40000 refers to 40000 MB, which is the size of the primary partition of the hard disk, for example, if your Windows 7 disk is attached to drive C and you want to increase the size of drive C, set the number here. My hard drive is 720 GB, so the number I enter here can be larger than 99000. If you are not sure, fill in the number between 40000 and 60000. Generally, this is okay. 13. Now your hard disk is changed into two parts: one is the partition you just specified, and the other is the remaining space. You can continue to partition the remaining space. Note that each partition must be formatted before it can be used. You can format the current partition, or reformat the partition as needed. 14. At this time, you may not be able to mount a trojan. Please restart it first. 15. After restart, the hard disk partition will still be selected. Try it now and you should be able to install it. If not, go back to the BIOS page, select Boot Mode: Legacy, and restart. I tried it several times to install it successfully. It may take some time for the computer to adapt. Do you want to switch to Win7 immediately? 16. After Windows 7 is installed, no driver is needed and it can be used properly. Sony drivers are available at this URL: http://service.sony.com.cn/vaio/Download/54063.htm This website is dedicated to VAIO SVE14A2 series laptops and is specially used for Windows 7 systems. Although Sony's repair site does not support changing the series of computers to the Win7 system, it provides a corresponding driver on the website. It seems that every time we live a door, it always opens a window. I have only installed the NIC Driver. I am afraid to install other things. Who knows what will happen. 17. General Win7 installation disk, after installation, is only a trial version, there will be a time limit. Use the corresponding cracking tool to change it to a genuine version.
