P25W V2 SP2 + Windows 10

Greetings all,
I've been upgrading a couple machines today to Windows 10 and it's been a pretty straightforward process. Unfortunately I've come across a few oddities on my P25W laptop:

Issue #1. After the install finished, all POSTs take a bit longer (30 seconds or so). With Win 8.1, I'd see the Gigabyte logo at power-up, followed almost immediately by the Windows "spinner", and then a login screen. (Then weird WiFi issues, but thats another topic)
After upgrading to Win 10, I'll see the Gigabyte logo at power up, as well as the startup options (F2 for BIOS, F12 for BBS, F9 for Recovery). It will sit at this screen for almost 30 seconds, my fans running at full speed. Then the options disappear, the Windows spinner comes up, and I've got a login screen in seconds.
Is anyone experiencing a similar issue?

Issue #2. I see an "Unknown USB Device (Device Descriptor Request Failed)" with a code 43 in my Device Manager. I'm fairly certain it's my Bluetooth driver. If I find a driver that works, I'll update here.

Cheers!

 

Fix for Issue #2! Press Fn + F11 to disable bluetooth, wait a few seconds, and then press Fn + F11 to enable Bluetooth. Now the hardware shows up and my device manager is all happy.


...Here's where it gets weird: that fixed my first issue too. Now my machine boots to a login screen in about 5 seconds.

I guess we're all solved!

Other notes:
I'm a fan of clean installs. Since Win 10 tries to load any drivers that are missing, I went ahead and loaded the chipset, Me, bluetooth, cardreader, audio, and touchpad drivers from gigabyte prior to connecting to the network (I also installed the Win10 WiFi driver from Intel). Finally, I installed the despised smartmanager app, rebooted, connected to the network, and let Windows Update take care of the rest (it downloaded the latest and greatest video drivers!). It was then when I did my bluetooth toggle trick.
Good luck, and happy upgrading!

 

Hello,

Just to add to this thread that has been very helpful for me. I had two issues with the upgrade to Windows 10.

1. Error code 80070002
First, I just tried to upgrade to Windows 10 from Windows 8.1 and the upgrade would cancel itself with the error code: 0x80070002. The Microsoft official explanation: "This problem occurs when some files in the Windows Update are missing, even though the update is downloaded and extracted successfully."
Behavior: the system would download the windows 10 via Windows Update, would display the message that is pre-loading and after it restarted itself would display the boot screen for a second, then it would restart again and would load Windows 8.1 that will show the above mentioned error message.

I have afterwards perform a clean install of windows 10 (previously I had downloaded the drivers from Gigabyte Windows 10 P25w v2 page) and had the same result with the same error code.

Turns out that the cause for me was that I had a recovery partition on each drive instead of having one only on the system drive so the update would fail. To better explain, when I purchased this laptop, a major decision point was the fact that it could install 2 additional M-Sata SSDs. The first thing I did when purchased has been to add a SSD and clone the initial hard drive to it then format the hard drive. I forgot to delete the recovery partition on the initial drive so this entire time I had two receovery partitions on my system (original one on the classic hard drive and the cloned one on the ssd). I backed up my hard drive contents on an external hard drive, deleted the recovery partition and included it in the regular one and performed a clean install of windows 10 and it worked.

2. Bluetooth not working
After I installed all the drivers the Bluetooth was displaying an exclamation mark in the Device Manager. When right clicking the device for Properties the message displayed was "Error Code 10 - the device cannot start". When trying to update the driver the system displayed the message "Windows encountered a problem installing the driver software for your device. Windows found driver software for your device but encountered an error while attempting to install it". After some research on the internet that lead to no conclusion I have decided to uninstall the drivers in order and re-install everything. It turns out that the Intel Bluetooth driver is conflicting with the Intel LAN driver. When I first installed Windows 10 I have decided to install the Bluetooth driver as a later step (the last one before installing the card reader driver) and it could not install since the LAN driver was installed before and probably used some services, files, etc.
The solution is to install the Intel Bluetooth driver before the LAN driver.
