Windows 10: Dual boot BIOS settings changed by windows update

I have a very annoying situation: I am runnig my laptop (Acer Aspire E 15) as a dual boot with Ubuntu (Linux) and Windows 10. To do this I had to change the BIOS settings:

1. Enable the BIOS bootmenu "F12"

2. Adress a safe boot option (in my case the Ubuntu partition) and give it a name.


So far so good. Everyting worked. Until I installed a major Update from Windows Update... Suddenly Laptop didn't respond to the F12 button anymore during boot, but went straight away to booting Windows.


Back to my (password protected!!) BIOS. I was flabbergasted to see that the Update of WIndows changed my BIOS settings back to the original settings!!


Of course I immediatly changed the settings back to my preferred settings and everything works fine again.


But... How the f*** is it possible that Windows Update changes my BIOS settings? How can I prevent this annoying behaviour of Windows? Microsoft seems to act as if their OS is the only one there is. But every now and then I really need Linux!

Dual Booting with Windows 8.1


The procedure below will allow you to boot Windows separately or in dual boot configuration.
Here's what I recommend to do:

1. Disconnect the drive containing Windows 8.1
2. Install Windows 10 with one drive connected.
3. After step 2, reconnect the drive containing Windows 8.1
4. Boot up Windows 8.1. Open disk management and take a note of the drive letter of Windows 10 OS.
   NOTE: if you boot up Windows 10, then take a note of Windows 8.1 drive letter
5. Open Admin command prompt and type: bcdboot X:\windows where X: is the drive letter of Windows 10 (Windows 8.1 if you boot from Windows 10 in step 4)
6. Reboot the PC. You should have a dual boot screen.

NOTE: To break off the dual boot setting, Win+R->msconfig->boot and delete the none default entry on the list.

 

Instructions to change board?

Boot off of the windows CD, repair your XP partition (hopefully you won't have to reinstall windows), install drivers, and you're good to go. You'll see dual channel mode in the BIOS splash screen results from POST. It'll be pretty obvious *Stick Out Tongue . Here's a list of general tweaks for the 939Dual-SATA2.
Step one- Set time, date
Step two- In CPU settings, disable cool n quiet, set memory clock to DDR400, play with memory timings (CAS-TRAS-TRP-TRCD), which are listed in the bios in the order CAS, TRCD, TRAS, and TRP. EDIT- new BIOS's mess around with this order, can't be too sure on it, but yeah at least you know what the RAM timings stand for *Big Grin .
Leave MA timing at 2T unless you think your system can handle 1T
Step three- in Chipset settings, enable onboard LAN, disable onboard Audio, disable AGP fast write, set primary graphics adapter, and set CPU-NB and NB-SB link speed to 1000mhz.
Step four- in IDE, disable controllers you aren't using. On all drives detected, enable SMART if you can and set PIO/DMA as high as they will go.
Step five- Enable legacy USB support
Step six- Set password if you're worried about anyone screwing around with your BIOS settings
Step seven- Configure your boot sequence. I reccomend hard drive first, optical drive second, and floppy drive third.
Step eight- Save changes, boot into XP, and enjoy your computer.
