Windows 10: Can't access Asus P5LD2 BIOS after Windows 10 update Threshold 2 10586

Hi Folks. Last summer I updated Windows 7 to Windows 10 Threshold 1 10240 on this old Asus P5LD2 motherboard based system I use for testing from time to time. I just updated it to Threshold 2 10586, and now I find I can't access BIOS boot settings anymore via the F2 key.

The only solution I can find on this refers to disabling Secure Boot in articles like this one or like this one that involves systems with a UEFI based BIOS.

Everything I can find refers to restarting Windows 10 and selecting:
Troubleshoot > Advanced Options: UEFI Firmware Settings
However there's no such menu when I go there since there is no UEFI on this old CSM based motherboard.

Has anyone run into this issue and perhaps found a solution?

Thanks for any feedback.

:)

 

Windows 10 Automatic Updates are killing my monthly internet cap

This update comes out next week.

Windows 10 Build 10586 Launches as Threshold 2

 

get the windows10 iso file

Hi. At the first Soryy because I can't speak english well.

I bought a asus n550jk with the original windows 8.1 home editation

And about 2 mounth ago update it to windows 10 home but after update it to bild 10586 I can't connect to internt.

please help me. Thank you.

 

The fast boot is the issue, even on non UEFI BIOS'.

One option is to boot up then "Restart" and on the restart you can access the BIOS.

 

This is the place to get quick, accurate answers about Windows issues. I'll be back.

I had disabled fast boot in power settings as per other advice, but just doing that didn't get me to BIOS on a cold boot.

Thank you so very much for that fireberd.

EDIT: You said that was one option. I wonder it there's another that doesn't involve having to boot into Windows 10 first.

 

I don't know if there are more options. Just one that I know has worked for me.

 

Did the Windows 10 10586 update insert code into the BIOS to enable Fast Boot and Secure Boot, and resulting in this issue? I was wondering if backing up BIOS and flashing it again with the newest again would fix things. But I'm wondering too if that might result in Windows 10 not being able to boot at all... the reason I'd hope restoring the BIOS backup would fix things. Though I see articles saying restoring BIOS backups is not always possible or advisable.

 

Disconnect your hard disk from your motherboard and try to get into the BIOS. Also is it the Delete key that enters the BIOS?

 

You know, this afternoon I find I can hit DEL at boot (yes... it's DEL) and the system will boot into BIOS setup now! The other night I had found information that said I could resolve this problem by disabling fast boot. It didn't seem to work for me. But maybe when I disabled fast boot I may have needed to fully shut the system down in order to get it to stick.

I'm still intrigued by the possibility that MS may be writing code to BIOS, otherwise I can't explain how this issue came about in the 1st place.

 

Fast startup does definitely write to the BIOS in terms of the boot order in old legacy systems. If I have fast startup enabled, I can't boot to a CD or USB drive, even if it's set as the CD or USB first in the BIOS. Fast startup is a hybrid sleep/hibernate feature, which logs you off the system, and then saves all the system information into the hiberfil.sys file. Once the computer is turned back on, it's almost like resuming from sleep or hibernate, but still posting for initialization of devices, and then boots from the hiberfil.sys file for faster boot.

Secure boot will not be on your machine. Secure boot is only on UEFI systems only. And Secure boot is only designed for Windows 8 and 10.

I've owned a lot of ASUS Motherboards and have been happy with all of them.

Right now I have Windows 10 on my ASUS M5A99FX PRO R2.0 with an AMD FX-6300 CPU. Runs awesome

 

Wow... booting is significantly faster with fast boot set. That's nice. While I was turning that on and off to test speeds, I discovered with fast boot set, I can hit F8 and at least have setup present a menu I can select a drive to boot from.

This was very inexpensive board I got on sale with an Intel CPU way back, and my 1st Asus. Perhaps because of the low cost, the BIOS has always been flaky, esp when it comes to detecting USB drives. Even with SATA drives there have been times when I had to disconnect all of them, and then add them back and boot them one at a time before it recognized them all properly. Or maybe that was me... I forget a lot if I let a number of years go by without working on these systems. I do know Asus boards have generally been well reviewed through the years. I got an MSI the last time I built a new system and have been very happy with it.

Now it's off to update my newest, a Win10 Toshiba notebook from 10240 to 10586, which was the whole reason I did this dry run on the old Asus. Hopefully that goes a bit more smoothly. It was kind of a dry run on these forums too. Glad to be getting some informed and accurate feedback here.

 

Do be careful with the upgrade. If your laptop seems sluggish after upgrade, let me know. The upgrade does cause some issues

 

I had originally intended to do a dry run of 10240 to 10586 on the old Asus and posting here about it to get a handle on how well both went. The update was hellish even before this issue of missing BIOS setup at boot, Feedback here was the bomb!

I had thought I'd ask here about what might be the recommended method for updating the Toshiba that I had uninstalled 10586 from when it 1st came through (had to do that to install a Toshiba update 1st). But at this point I'm pretty convinced that the best method to update 10240 to 10586 again is to run Media Creation Tool and just select the default "Upgrade this PC now" option. It seems that works a lot like the way Windows Update does by first examining the existing OS configuration, and then deciding exactly which fines to download and install.

On the Asus I had Media Creation Tool download the whole ISO and made the huge mistake of trying to update from that via a virtual drive from within 10240. Don't ask... I have no idea how it got into my head to go that route other than just end of the day exhaustion.

It's late now here, and if updating the Toshiba goes like it did after I finally re-installed Windows 7 on the Asus, and then just letting Windows Update take it to it 10586... it'll take a few hours. So I think I'll wait and do it tomorrow.

I did create 2 images of the drive too... one with Win10's own Backup and Restore, and one with Acronis 2016. Hopefully one or the other will restore a decent image if needs be. There's so much new to me in Windows 10, I really want to dot all the i(s) and cross every t before I risk doing something stupid to the new Toshiba.

 

The best thing to do if you do go to 10586 is to do a clean install. I had to do that on my PC because the update caused a lot of issues. Boot times are very slow, and the install will create extra recovery partitions, and takes up space, thus slowing down the computer.

The most common problem after the upgrade are system freezes and driver issues. There have been lots who have had a good upgrade experience, but there are those who havent.

You can download the ISO and burn to DVD or copy to flash drive with the media creation tool.

If you do decide to upgrade, I hope it goes smooth for you.

And you have done well with backing up your stuff. If you backed it up to an external drive then you are good to go

 

Wow. It can install extra recovery partitions! ?#@*%!? ...I wonder if there's an option to remove all the old OS data after the update that would clean that up.

Driver issues. Someone else suggested doing a clean install, and the reason I balked at that was the ordeal of tracking down and downloading all right drivers that came factory installed on the system.

When I bought my previous Toshiba in '06, I made sure I got one with system restore disks. I thought they'd restore the system to its factory setup. But no. When Win7 became unbearable, which it inevitably does at some point, I ran the restore disks, and what resulted was a mess. I ended up deleting every partition and updating Vista with a fresh copy of Win7. I'd downloaded all the drivers to tune things up, but it was an energy intensive process.

I don't understand why MS decided not to offer the update to 10586 via Windows Update again after I uninstalled it. But that's for the folks with six digit incomes to decide I guess. I do have both drive images on an external USB backup drive. Will keep you posted lmaneke.
