I have a Dell XPS 8700. I upgraded from Windows 8.1 to 10. As recommended, I also updated the bios to A11 (the latest bios). I have an i7 processor, 24gb RAM and an SSD as the boot drive - so it should be a very fast machine.
The boot time for just the bios (i.e. excluding Windows 10) is 14 seconds - crazy long. It takes longer for the bios to boot than it does for the time it takes for Windows 10 to boot. Note, the bios boot time is confirmed by opening task manager and looking at the startup tab.
My previous bios version was A03, which was still slow at booting up (about 8 seconds for the bios to boot), but better than A11. I note that some of the other bios versions subsequent to A03 were also slow to boot and I deliberately downgraded from those versions to A03 to improve boot performance.
How can this bios boot time be speeded up because it doesn't seem normal for it to take so long?
Note - I have external USB hard drives and I have tried disconnecting these and it does not impact the bios boot time.
Solved! Go to Solution.
I have two XPS 8700s that were upgraded from Win 8.1 to Win 10 and our machines appear to have somewhat similar specs (my 8700s both have an i7, 16GB RAM, and SSDs).
I updated the BIOS to A11 and it is taking an eternity to boot Win 10 when compared to boot times when I was running Win 8.1 with BIOS version A10. In fact, I would be overjoyed with the 14 seconds you're seeing.
On the last restart of one of my 8700s, I saw 21 seconds in TM (and THAT was a restart). On a cold boot (machine completely shut down and then later powered up) I most recently saw 44 seconds!
I have quite a few connected devices (1 SSD boot drive, 1 internal HDD, 1 internal SSD, 2 external HDDs, 2 USB flash drives, 2 printers), but the configurations didn't change after upgrading to Win 10 and the A11 BIOS version; they're the same as when I was running Win 8.1 with the A10 BIOS.
I should note that, in addition to updating from A10 to A11, I also updated most of the drivers listed for my machines on the Dell support site (audio, wireless, chipset, network, IRST) so I'm not sure which is the culprit (or culprits) and I am also not sure whether or not the extended boot times are related to the OS itself. Regardless, the length is simply unacceptable and I can only hope someone at Dell has some insight.
The BIOS start time got really slow around A06 or A08.
90% of the time don't shut down my XPS 8700s now that they are on A10 due to the very slow boot times. In stead I put them to sleep and with win 8.1 it wakes fairly quickly.
I have also resorted to Sleep when I am not going to be using my 8700s for several hours or more. The boot times with Windows 10 and A11 are just stupid slow.
The boot times with Windows 8.1 and A10 are by no means as fast as they should be, but they are certainly not as slow as they are with Win 10 and A11.
I recall a few earlier BIOS versions where slow boot times were resolved, at least somewhat, by disabling the Bluetooth and/or wireless driver. However, I currently have Bluetooth drivers disabled and even that does not help with Win 10 and A11.
I hope Dell can come up with a resolution for this issue because it is annoying, unwarranted, and simply unacceptable.
Wow, is there anything worth it in A11?
A11 is needed for Win10 from what I have read. I haven't gone there so I have not updated.
A10 is needed for GTX 9xx graphics cards.
A06 solved the beep on startup with GTX 7xx graphics cards.
I have one 8700 with A06 and one with A10 and the A10 is slower. I haven't timed it.
My Dell XPS 8700 built in late 2013 is running A03 BIOS, Win 8.1 on a 250gb Samsung 840 EVO SSD, and it boots in about 6-7 seconds which is pretty fast. I am tempted to upgrade the OS to Win 10 but am hesitant if Win 10 requires a BIOS upgrade to A10 or A11, which would apparently more than double the boot time.
I have another XPS 8700 built Nov 2014 on A09 BIOS, running Win 10 on a 250 gb Samsung 850 EVO SSD ,and it boots in about 11 seconds; slower but not bad.
Will my older Dell XPS 8700 A03 BIOS run Windows 10?
Anybody tried turning Secure Boot off in BIOS to see if that speeds up boot time?
