Advanced Startup Options In Windows 10. Change Boot Defaults When Dual-booting.
Secure Boot is an important security feature designed to prevent malicious software from loading when your PC starts up (boots). Most modern PCs are capable of Secure Boot, but in some instances, there may be settings that cause the PC to appear to not be capable of Secure Boot. These settings can be changed in the PC firmware. Firmware, often called BIOS (Basic Input/Output System), is the software that starts up before Windows when you first turn on your PC.

Administrative privileges are required to use BCDEdit to modify BCD. Changing some boot entry options using BCDEdit could render your computer inoperable. As an alternative, use the System Configuration utility (MSConfig.exe) to change boot settings.
To change boot options programmatically in Windows, use the Windows Management Instrument (WMI) interface to boot options. This BCD WMI interface is the best method to programmatically change the boot options. For information about the BCD WMI interface, see Boot Configuration Data WMI Provider in the Windows SDK documentation.
But what about when you decide you don't want the second operating system any longer? Is there any easy way to remove the additional operating system entry from the boot manager to stop startup confusion?
Modern Windows versions store Boot Configuration Data (BCD) in a registry-like database. Previously, you managed your boot screen options using the tiny boot.ini file (and Windows NT boot loader, ntldr). However, a single insecure text file is vulnerable to attack. Hence, this was changed to a more secure but universal solution.
Another possible reason that you may not be seeing the dual boot menu is that you have Windows Fast Startup turned on. In this mode, when you turn off your computer, it logs out of your user account and then saves the state of the operating system to a hibernation file. When you reboot, instead of loading all the drivers and the current system state again, it just places the image from the hibernation file back into RAM, which speeds up the startup process.
I have a thinkpad x1 that has both windows and Ubuntu installed. When I installed Ubuntu I had to make some bios changes but recently I reset my bios settings and now it boots straight into windows, grub doesn't even pop up. Any suggestions for getting grub back?
Hello;If you have your windows data on a disk, then when when booting into Linux, simply mount that disk from Linux to access the data. Linux can mount NTFS drives and can read/write to NTFS disks. I do this all the time. When done with Linux, reboot to windows, and your updated data will be there on that disk.
If it's difficult to catch and the system boots to Windows instead, hold the Shift key while you restart Windows to enter 'Advanced startup' and look under the 'troubleshoot'/advanced options for the 'UEFI Firmware settings' to enter the BIOS.
(2) Enter BIOS -> Select [Boot] -> Change the boot device priority so that your USB drive/CD-ROM is the first boot device. Save and exit bios to keep this setting but you may want to change it back later to avoid booting to external devices/disks accidentally when they are plugged in/installed.
The Advanced tab requires administrator privileges to make most of the changes on this tab. Three buttons are here-Performance, User Profiles, Startup and Recovery and Environment Variables. For the most part, these settings should be left to Windows for automatic configuration. Still, there are times when you will need to make a change. For example, if you are dual-booting Windows 7 and another OS, you might want to make changes to the dual-boot menu (see Figure 11.12).
Boot menu is a menu you could access before entering an operating system. Each time when you start your computer, you can choose to access boot menu or not. You can load up other operating systems (or applications) manually by accessing boot menu and making changes.
You should select Advanced options for Ubuntu either when you need to boot with a different kernel other than the default kernel. Or if you face any issues within the system like file corruption, kernel not loading correctly.
By default, GRUB does not wait in the boot menu and starts booting immediately, in 0 seconds. You can change this timeout setting by changing the value for GRUB_TIMEOUT. The value will mean the number of seconds the menu is visible before booting starts. If the value is 5, the boot menu will appear for 5 seconds so that you can select which OS you want to load when the system starts.
Once you have left the standard Windows interface with one of the above access methods, the startup screen for the system recovery with the advanced start and repair options will appear after a brief moment. To reach the start settings for Windows 8 safe mode, proceed as follows:
The /etc/default/grub file is used by the grub2-mkconfig tool, which is used by anaconda when creating grub.cfg during the installation process, and can be used in the event of a system failure, for example if the boot loader configurations need to be recreated. In general, it is not recommended to replace the grub.cfg file by manually running grub2-mkconfig except as a last resort. Note that any manual changes to /etc/default/grub require rebuilding the grub.cfg file.
Manual changes to the /boot/grub2/grub.cfg persist when new kernel versions are installed, but are lost when re-generating grub.cfg using the grub2-mkconfig command. Therefore, to retain password protection, use the above procedure after every use of grub2-mkconfig.
Menu entries can be modified and arguments passed to the kernel on boot. This is done using the menu entry editor interface, which is triggered when pressing the e key on a selected menu entry in the boot loader menu. The Esc key discards any changes and reloads the standard menu interface. The c key loads the command line interface.
UEFI Secure Boot does not prevent the installation or removal of second-stage boot loaders, nor require explicit user confirmation of such changes. Signatures are verified during booting, not when the boot loader is installed or updated. Therefore, UEFI Secure Boot does not stop boot path manipulations, it helps in the detection of unauthorized changes. A new boot loader or kernel will work as long as it is signed by a key trusted by the system.
While this will install the packages, you will need to use the advanced settings option in the GRUB menu when booting to select them, as the default option is to boot with the newer version. Reboot again, making sure to select the 3.16 version of the kernel as described.
Users may need to replace their boot drive on occasion, but not everyone knows how to change boot drive windows 10. Although changing the boot device using your computer's firmware is the most popular technique, it is essential to note that it is not the only one. Some installation, diagnostic, and recovery tools may need changing the boot drive. In this post, I'll explain all you need to know about changing the boot device in only a few minutes.
If you changed the boot disc for some reason, such as installing Windows or wiping some material with malware, you should remember to make a backup. It is something that is often forgotten or overlooked. There is always a solution for how to change boot drive windows 10; this is Tenorshare 4DDiG, dependable, professional, and safe software that will help you recover your files even if your drive has been formatted.
Yes, you can change the boot order in the BIOS settings menu's Advanced tab. To change the boot order on most PCs, restart or turn on the computer. To access the BIOS settings menu, hit the f10 key when the display is blank.
In Step 4, we set the first boot device to the CD-ROM Drive as an example. As you can see in the screenshot above, the computer is attempting to boot from the CD but is asking for a confirmation first. This only happens on some bootable CDs and will not show up when booting to Windows or other operating systems on a hard drive. Configuring the boot order to boot from a disc like a CD, DVD, or BD is the most common reason for making this change, so I wanted to include this screenshot as an example.
Windows 10 offers a lot of interesting features, and the advanced boot options to troubleshoot many of the Windows 10 problems, is one of them. You can reset your PC, restore it to a previous state, boot to a different operating system, use "Startup Repair" to fix startup issues and boot Windows 10 in safe mode to troubleshoot problems.
By default, Windows is set to restart in advanced boot options, if it fails to start up. If any startup error is causing your Windows to crash, then it may automatically launch the boot options for you. However, it is not compulsory and Windows may get stuck in a boot cycle.
Holding Shift key and restarting the PC is definitely the easiest option to access Windows 10 boot options. However, if Windows is acting up and you are unable to boot properly, then a recovery or installation drive will help. If you know any other ways to access Windows 10 advanced boot options, let us know in the comments.
All menu entries can be password-protected against changes by setting superusers, which can be done in the /etc/grub.d/00_header or the /etc/grub.d/01_users file. The 00_header file is very complicated and, if possible, avoid making modifications in this file. Menu entries should be placed in the /etc/grub.d/40_custom and users in the /etc/grub.d/01_users file. The 01_users file is generated by the installation application anaconda when a grub boot loader password is used in a kickstart template (but it should be created and used it if it does not exist). Examples in this section adopt this policy.
