       Recently, many netizens have asked, "I can't find the driver when I install the original win10 or win11 on my new computer. I can't find the hard disk when I enter the third-party PE. After I find the hard disk and install it, a blue screen appears during installation. What's wrong with the new machine?" This netizen was a little upset and didn't know the reason. In fact, these are all because the vmd mode or raid mode with vmd function is enabled by default in the bios. Since the original win10 or win11 system lacks the vmd driver, the vmd mode in the bios needs to be changed to ahci. Here are the detailed steps to change the computer vmd to ahci mode. 

 

       WhyHow to change the hard disk mode vmd to ahci in bios?

       For processors of 11th generation and above (Intel Tiger Lake), the default BIOS has RAID mode or VMD mode with VMD function. When it is enabled, some PEs that do not support VMD function will fail to recognize the hard disk.You can also go to BIOS, go to Advanced and change the interface mode of your hard disk from vmd to AHCI. After entering PE, you can see your various hard disks.You only need to download the latest version of PE. It is recommended to boot it with a USB flash drive, and then install it to the USB flash drive. Generally, the problem can be solved.
