Windows Update identifies SSD as a USB flash drive.
Windows Update identifies SSD as a USB flash drive.
I'm currently on Win8.1 and was trying to install Win10, but when I start the update, it tells me "You can't install Windows on a USB flash drive using Setup." I have no USB storage devices plugged in currently, and the SSD shows up as a disk drive in Device Manager. The only thing related to this issue is that sometimes when I boot up, a message will pop up saying "Keep USB plugged in" or something similar. It doesn't happen every time, but hopefully that gives some insight as to the problem. Any help is greatly appreciated. Thanks!
Your SATA controller drivers are current. The SATA controller is configured in AHCI mode within the BIOS/UEFI settings.
Your drivers are current, yet configuring AHCI remains challenging. You mentioned needing to modify the registry, but it’s unclear exactly which entries to adjust. Could you share more details about your system and the error messages you’re encountering? Your guidance would be invaluable. Thank you!
No need to edit registry, you should be able to do that when you enter BIOS/UEFI. It "should" look like this, or rather you should have an option like this: This is an example, it will vary on the manufacturer. What's your MBO?
Begin by opening the registry editor via regedit and entering the path. Navigate to the specified registry paths: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\msahci, then HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\pciide. Locate the "Start" entry in each section and adjust its value to 0. Restart your machine and enter BIOS/UEFI settings, configuring the SATA controller to AHCI mode as per your motherboard manual. Save changes and exit BIOS. Install the necessary drivers for your motherboard or SATA controller. If issues persist, verify the correct controller setting in BIOS and consider reformatting if needed. Remember to switch to AHCI before launching Windows setup.
Ensure AHCI is activated in the BIOS settings. Open Device Manager, navigate to "Disk Drives," double-click your HDD/SSD, and under the "Policies" section, verify "Better Performance" and "Enabled write caching" are selected. Confirm OK, then restart your computer.
