    AHCI installation every time on startup?


    While running Win7 (before upgrading) I was using IDE for disks and manually switched to AHCI and installed it in Windows, but now there is an extra loading screen on every bootup that takes 15-20 secs with "AHCI is installed" at the end, is this extra loading process normal or is it installing itself every time? Sorry if it seems obvious, this is my first time using AHCI.

    This extra screen is not something usual.

    Check device manager, if you have proper AHCI drivers installed, an also what is running at startup (task manager is good for first look)

    Are you referring to the POST screen? When you first power on, before Windows even starts loading? If so, that's a function of your BIOS and there is nothing that can be done to fix that (other than turning off AHCI or getting a new motherboard).

    not normal if it is installing the AHCI Driver every time you boot , are you still in win 7 or Upgraded to Win 10?

    Here are Two Tutorials that may help you figure out what is wrong.

    Well it seems to be installed, the only thing unusual is a strange drive name in the drive list and this mysterious "recovery" partition that is empty.

    It's an extra screen in the post stage (before windows) that specifically talks about AHCI, normal POST screen is still there.

    I switched it in win7 before upgrading to 10 so I followed the 1st guide but sadly it doesn't mention anything about loading/installation screens.

    That's what I thought. Many older motherboards have this because AHCI was a BIOS extension. Newer UEFI motherboards have AHCI built-in to the firmware, so you don't see something like that.

    As I said above, it's not something you can control short of turning off AHCI or getting a new motherboard.

    Mystere is correct I believe , I get the same thing for my Raid Controller , even on my new X99 system. It is the Bios setting up the AHCI Bios Driver (extension), on my x99 system with Raid0, that happens even before it Posts.

    The 450mb Recovery partition is normal in windows 10 , it should contain the Win10 recovery Environment and a File called Wim.re , which you will probably need a program like Minitool Partition Wizard 9 to see , with it's "explore" Drive (partition) Option as the Recovery files are usually hidden and or Protected by Windows 10 .

    Also Thanks, so its normal for this part to show as 'empty'?

    Hatemf23, it would be good to specify your motherboard anyway. Because in the last 10 years or so, PCs don't need more than few seconds to go through the BIOS and 20 sec for this screen seems a bit too much for me.

    Its a EX58-UD3R which is kind of old, so it makes sense. also 20 secs might be a bit too much I never measured it but its somewhere around 10-15 secs, which is not a big deal as long as the BIOS is working as its supposed to.
