Lenovo E430 uses a mobile hard drive for system startup

Lenovo E430 used a mobile hard drive as a system to start for a few days and used the Department's computer for a business trip. However, I did not like the software installed in the Department's notebook and could not uninstall it, even if I use a mobile hard disk as a system, start it from my mobile hard disk. However, when I use a virtual optical drive to load the iso file and directly run the installation, I am prompted that the file cannot be installed on my mobile hard drive, as shown below: windows cannot be installed on this disk. The installer does not support configuring or installing a disk connected via usb or ieee 1394 port. Is it swollen? It seems that you can only try to install it from winPE. If the same error is prompted after entering the result, you can use wim to install it. Haha, you can finally install it on my mobile hard drive. Wait for the restart and have a cup again. Blue Screen !!! No, gg did not find a solution, but some people mentioned the problem of IDE and AHCI. Let's take care of it and enter the BIOS, we found that the hard drive mode of Lenovo E430 BIOS is AHCI by default, and the other is compatible mode. We hope this compatibility mode can be used. After the settings are complete, restart again and enter the mobile hard drive startup mode. Well, if you don't have a blue screen, you can continue to configure and install Windows 7. For the rest, Enjoy!
