Windows 10 Overrides boot settings in UEFI BIOS, requires Live CD fix to repair

I have been dual booting for years now and have problem I can’t seem to solve myself. As we all know Windows is an arrogant dick, and in my case whenever I chose to boot to it it will, automatically without asking me, alter my boot up settings in my BIOS and make itself de-facto king. Mildly annoying as all I had to do with enter setup, change the boot order and carry on.

Now however it is ALSO deleting the grub entry option in my BIOS, meaning I need to load a Live-USB and perform a boot repair (or what have you) to fix it. Long winded just to fix grub.

Now, several questions:

  1. How do I stop Windows 10 from doing this? (would fix all my problems)
  2. Else, since this never used to happen, is there a way of remaking the Grub boot option in my BIOS without a long winded string of commands to reinstall grub? (why is the grub option now not sticking around)
  3. Would I be better of not using EFI boot options if possible (all of my disks are less than 1TB) if that’s possible.

Using an AsRock Z77 Extreme 4 motherboard. Have 3 SSD’s laid out like this currently (in case my method is just wrong someone can correct me):

  1. Disk A is 240GB and used for Windows. I left 550MB free for another EFI partition and let Windows do it’s thing with the rest of the drive.
  2. Disk B is 120GB and used for root, and it has a ‘backup’ partition on there (not required by either OS on boot).
  3. Disk C can be ignored essentially, 1 partition, mounted to /home and used only by Linux.

    NAME FSTYPE SIZE MOUNTPOINT LABEL sda 238.5G
    ├─sda1 16M
    ├─sda2 ntfs 237.9G
    └─sda3 vfat 525M /boot/efi
    sdb 119.2G
    ├─sdb1 ext4 62G /media/root/Furnace Furnace └─sdb2 ext4 39.4G /
    sdc 477G
    └─sdc1 ext4 477G /home

What do now?

Can a virus destroy the BIOS of a modern computer?

In the late 1990s, a computer virus known as CIH began infecting some computers. Its payload, when triggered, overwrote system information and destroyed the computer’s BIOS, essentially bricking whatever computer it infected. Could a virus that affects modern operating systems (Like Windows 10) destroy the BIOS of a modern computer and essentially brick it the same way, or is it now impossible for a virus to gain access to a modern computer’s BIOS?

MSI B450-A PRO BIOS Update Issue

I recently completed a PC Build involving the aforementioned Motherboard. I booted into the BIOS and found that my BIOS version was not current.

After Attempting to flash a Bios update (Downloaded from here, Version :7B86vA7) my MotherBoard crashed with the progress bar at 47% and will not reboot Despite I checking and rechecking prior to flashing BIOS if the version I had downloaded was compatible.

where in this process did I go wrong?

Is the motherboard recoverable?

Help with dual boot: BIOS changed and I can no longer access Linux Ubuntu already installed

Two years ago, I downloaded the latest version of Linux Ubuntu to do dual boot with windows 7.

In this configuration, I do not remember what BIOS version was there, but I was always asked to choose which operating system I would like to start. Sorry if I’m saying something wrong, because I really do not know this in the depth I’d like.

A couple of months ago I decided to reinstall the copy of windows 7, but instead of backing up data (from windows) directly on an external hard drive, I decided to access these personal files through the Ubuntu OS, just copying them on the Ubuntu desktop in an organized way. I was pretending to copy them back to windows 7 after reinstalling it.

The problem is that I am no longer able to access Ubuntu (where my files are) since the new installation of Windows 7 also reinstalled the original BIOS. This BIOS does not give boot options and also does not give access to Ubuntu.

Windows recognizes the existence of the partition where the old Ubuntu was, but I can not access the data from there.

As an alternative to trying to get access to that data, I’ve downloaded a current version of Ubuntu, burned it (Live-CD), but even through Try-on live Ubuntu version, I cannot get access to the Ubuntu partition: it just shows some general archives but not personal data (such as desktop items, etc.).

If I understand correctly what happened, what can I do to change the BIOS and recover access to the version of Ubuntu that is already installed on my computer?

ACPI BIOS Error (bug): Could noy resolve [^^^RP09.PEGP], AE_NOT_FOUND (20180531/psparse-330)

Everytime I try to boot my laptop, these two lines error appear three times and won’t let my laptop boot.

The last thing I was doing was trying to install atk.

How do I verify the latest Dell A10 BIOS is installed?

Dell released the A10 BIOS 19 May 2008 and updated it 21 June 2013.

From Terminal:

user@latitude-d620:~$   sudo dmidecode -s bios-version A10 user@latitude-d620:~$   sudo dmidecode -s bios-release-date 05/16/2008 

This date does not match Dell’s. man dmidecode does state, “[Because it does not] probe for the actual hardware[,] the presented information [is] possibly unreliable.” Is this an example of unreliableness? Does this date indicate when the BIOS was last updated, demonstrating mine is outdated? or only the release date itself, implying nothing about when mine was last updated?

How do I determine whether my “A10” is the 2013 updated version?

How do I use a .CAP file to update BIOS driver

I just built a new PC and am in the process of installing the latest drivers from my motherboard manufacturer’s homepage here (I have an ASUS ROG STRIX X470-F Gaming motherboard). There is a driver for the BIOS (first in the list) which I would like to install. However, when I download the ZIP file, all it contains is a single .CAP file and I don’t know what it is nor what to do with it.

My question:

How do I use this .CAP file to update the BIOS driver?

Enagble Supermicro Virtualization in Bios

my motherboard is a Supermicro x9dri-ln4f+, and I am using dual xeon e5 2690 CPUs.

I have been trying to enable Virtualization in order to load VMs in qemu and virtualbox.

The motherboard claims to support VT-x,VT-d, and VT-c in the specs page, and the in the bios under cpu information, it states that all three of those are supported for the CPUs.

This issue is extremely similar to enabling virtualization on supermicro board but their solution of enabling NX(XF for me) did not fix anything, because it was already enabled.

Things I have done:

  • Enabled “
  • Enabled Intel VT-d in North Bridge->Integrated IO Configuration
  • Enabled DCA in North Bridge->Integrated IO Configuration
  • Enabled Isoc in North Bridge->QPI Configuration
  • Enabled Execute-Disable Bit Capability(Solution to other person’s issue)
  • Enabled Intel Virtualization Technology in Advanced settings
  • Tried combinations of enabled Prefetcher settings in advanced such as MLC Streamer, MLC Spatial, DCU Streamer, DCU IP
  • Tried settings bios to default settings and repeating above settings.
  • Full boot and power cycle(completely off) after changing bios settings.

Additionally, from https://www.thomas-krenn.com/en/wiki/Activating_the_Intel_VT_Virtualization_Feature doing:

modprobe msr rdmsr 0x3a 

returns 0

Also running dmesg

$   dmesg | grep kvm [    14.444265] kvm: disabled by bios [    16.225445] kvm: disabled by bios 

And in windows under cpu info in task manager it says that virtualization is disabled.

Any help is appreciated, as I have been racking my head for hours trying to get this to work.

What motherboard has BIOS that allows for better customization of BOOT priorities?

I have a GIGABYTE GA-H170M-D3H DDR3 motherboard. The way this motherboard handles my boot priorities is a serious pain.

I have a harddrive with windows 10 and another one with Ubuntu. Whenever I decide to boot from the Ubuntu harddrive, it makes it so my computer always starts with the ubuntu drive. I’ve tried going into the BIOS to change this, but it doesn’t give me the ability to do so. As of now, I keep having to go into the BIOS to boot from windows 10. On the BIOS Features screen of the BIOS, i’m not even allowed to select the hard drive that has windows 10. I have to manually select the hard drive to boot from every single time. By hitting F12 on the motherboard.

If there was a way I could have the BIOS ask me which hard drive i wanted to start from everytime, that would also be nice, but I have a feeling the BIOS in this motherboard just isn’t very user friendly.
