    Any idea why my BIOS takes so long to load?


    43 seconds to be precise, according to task manager. After that W10 takes equally long to get to log in. Having an NMVe drive, I assumed the whole process would be a lot quicker, but really it isn't that much quicker than my old PC. My start up programs are showing low impact to none on start up. Any ideas/suggestions? Thanks.

    I'm field testing a new Dell XPS 9500 series laptop (I do field testing for Dell). Its a 10 gen i7 CPU with UEFI BIOS (what your 8930 has) and an M.2 SSD. It takes a relatively long time to boot up, longer than my older Inspiron 15, 5577 Dell laptop which is an 8th gen i5 with an M.2 SSD. The long initialization time was one item that I flagged to Dell on my initial evaluation.

    When it first powers on it runs a hardware self test, then the UEFI BIOS has to initialize and finally Windows initializes. The Windows log in shouldn't take too long, depending on what it has to initialize and access wi-fi, but the POST and UEFI BIOS is probably right. I have a self built desktop using an ASUS ROG (gamer) motherboard, i7 6700K running at 4 Ghz (much faster than your laptop) and its still slow on the POST and UEFI BIOS initialization, compared to my old desktop that had the conventional BIOS, not UEFI.

    This is from a cold boot. Restart is usually 8-8.5.

    Specs are below in My Computer.

    The only thing I have ever noticed in the past is having extra peripherals, especially USB storage devices, physically connected at boot time will drag it down. Not that familiar with the XPS.

    I have an Acer desktop, 2 years old, NVME boot drive, time to desktop from cold start is usually 7 - 9 seconds, but I did go into the BIOS (UEFI) and turn off all extras such as boot from network, any unused boot devices (CD/DVD/ HDD) etc, also fast startup (which seems to slow the POST for some reason).
    Some BIOS are particularly slow due to the amount of checking they do, there may even be a longer RAM check occurring which you can't alter, but turn off as much as you can that you don't need in BIOS and as said above, unplug anything not needed at boot time, see if that helps.

    Thanks, I've just reduced my Dell Latitude E7270's Last BIOS time (displayed in Task Manager on the Start-up tab) from 29 seconds to 11.0 seconds.

    But it still can't match the 8.1 seconds of my older slower Latitude E7440. That I put down to the amount of RAM that is installed and has to be tested in POST, 16GB for the 7270 vs 8GB in the 7440.

    Hi there

    @Bree

    I'm using an Older Hp Envy (sleekbook) with the "Classical SATA SSD" -- UEFI and intel i5 -- 8GB RAM (DDR 3 so not the fastest by today's standards) --- boot time is too short to even think of measuring it. (By boot I mean not until Windows is completely loaded but from seeing the HP boot Logo with the windows little circular thing of white dots spinning).

    However as far as I can measure it -- takes 4 secs from power on to showing the Windows login screen.

    Running from identical SSD (swap the SSD) running Arch Linux -- around 2 secs for the version with KDE GUI.

    Both Windows and Linux (depending what SSD is in the machine give perfectly decent boot performance times )

    Don't of course have too many external devices connected at boot -- the BIOS / UEFI checks to see if there's any boot record on them and then checks the default boot order in the setup to decide what device to boot -- all this adds to the time to boot.

    If modern laptops with faster disks and more powerful processors are taking longer to boot I suspect there's probably something in the BIOS firmware that needs fixing.

    Hopefully you guys who have this problem can post back when you've got it all fixed.

    BTW does it take a long time also to get into the BIOS boot menu at power on .

    Cheers

    Oh, yeah, I've got loads of them, about 10 external HDDs. I'll try it without them connected and see.

    I upped my RAM from 16 to 32 will that increase boot time?

    Yes, that screen shows that Windows has started to boot. But how long does it take before that screen appears? My splash screen before that (just the OEM logo) displays while the BIOS is running the POST tests. It's not until POST is completed that Windows can start to load. The time that takes is shown in Task Manager.

    It should do, there's twice as much RAM for the POST checks to test.

    Hi there

    if RAM is fast (presumably DDR 4) then the time difference between checking 16 GB and 32 GB is insignificant unless of course there are errors in the memory chips in which case replace them. It certainly won't be a "Linear" relationship --i.e 2X RAM will take 2X longer to check than 1X RAM).

    @Bree -- try booting say Macrium recovery from a "bog standard" SSD connected to the machine via SSD-->SATA-->USB3/3.1/USBC connector and see what the boot time is. If it's comparable to the internal Windows boot then there really is a problem somewhere in the firmware --- also do different versions of Windows 10 (e.g insider releases vs Standard releases) make a difference.
