Hi guys, I really don't have time to research this so I am hoping anyone can help me real quick. I have a system I did a UEFI install of Windows 8.1 on, after installation the UEFI has the Windows Boot Manager option in the boot menu of the UEFI rather than the drive itself. I was doing some testing on a new SSD, installed Windows on it and such, then went back to the old one and now the Windows Boot Manager option is gone. The only drive I have installed is the one with Windows 8.1 on it. How do I get the Windows Boot Manager option back in the UEFI? Thanks EDIT: ALL FIXED, FOUND GUIDE THAT WORKS! I'd try to wipe the settings of the UEFI/BIOS (I mean with the CMOS clear jumper or button or pulling battery).
I bet it will then try to rediscover everything on the drives on the next boot. On Linux, there's a tool 'efibootmgr' that can view and change the contents of that list that's in the UEFI, but the way its command line options behave seems pretty strange (feels like it's a waste of time to try to understand how it works). That's the only tool I've seen that can do something to the boot entry list in the UEFI.
I apologize in advance if I sound dense, but I'm seeing something in the BIOS that doesn't make sense to me. I have three different SSDs at this time, one each for 7, 10 upgrade, and 10 clean (the last is a slow work in progress). All of the SSDs are GPT. and SATA is set to AHCI in the BIOS. If I switch from one SSD to another and look at the BIOS before booting, UEFI: Drive 0 (brand/model) appears as the boot option from the SSD. If I reboot and look at the BIOS, the UEFI option is replaced with Windows Boot Manager. Is this normal?
If not, what am I missing?.I included the asterisk because I initially installed 7 as MBR, not knowing the difference. I was able to convert it to GPT using a separate SSD and a process posted at Macrium's website. This shouldn't make any difference in the BIOS, but I figured I'd mention it anyway. It's normal, the same happens on my system. The following explanation was found on Wikipedia: Unlike BIOS, UEFI does not rely on a boot sector, defining instead a boot manager as part of the UEFI specification. When a computer is powered on, the boot manager checks the boot configuration and, based on its settings, loads and executes the specified operating system loader or operating system kernel.
The boot configuration is a set of global-scope variables stored in NVRAM, including the boot variables that indicate the paths to operating system loaders or kernels, which as a component class of UEFI applications are stored as files on the firmware-accessible EFI System partition (ESP).

There are several ways to run multi-boot systems. You appear to have 3 ssd's each containing a separate OS.
You can setup each SSD with its own EFI/Boot partition - but the switch between OS's you would have to keep changing Boot Order priority in the BIOS everytime. Or you can setup ONE EFI/Boot partition on the primary drive - and when booted you will be given the option (via Bootmanager) to boot the OS contained on any of the 3 ssd's How are you managing the multi-boot option?? PS - all systems boot via a Boot Manager No matter MBR or UEFI What your Boot manager is telling me - Is that it does not display the option to select which OS to Boot.
I want to dual boot ubuntu 15.10 with already installed windows 10 (upgraded from 8). From what I've been researching, in order for ubtuntu to be dualbooted with windows 10 on a uefi machine, the ubuntu installation media (in this case a usb) must also be booted from uefi (as opposed to changing the boot setting to Legacy and booting from usb that way), so that the correct grub-efi, instead of grub-pc, is installed. I have a Dell Inspiron 7000 series with core i7 processor its 64bit and also boots windows with uefi. This dell does not seem to support booting a usb from uefi as no matter what I try, 'Boot from usb' will NOT appear under 'UEFI boot options.' The only way for me to boot from the usb is to boot in legacy mode and then select boot from usb. The problem is, when I try to install ubuntu this way, after rebooting, my system boots directly to windows 10 and the grub option does not even appear, let alone the actual bootloader screen to select which OS I want to boot.
I assume my problem is that I can not install ubuntu correctly since I have to boot the usb in legacy mode when trying to install. Also, the filesystem on the usb appears as FAT32 which should be recognizable to windows to support usb uefi booting Does anyone know of a way I can 'Boot from USB' with 'UEFI boot option'? I was following the steps on but under General Principles, number 5, I can not do this with my system. Can anyone help me with a workaround or anything?
I've had the same issue for 1 year now on my Inspiron 5567 Kaby Lake 7500U. The secret to install Ubuntu/Debian/any linux distrib on new Inspiron 5567 Kaby Lake is here: you need to create a special boot setup. Change default email program. For a dual boot with a Windows 10 preinstalled:.
Burn your iso with Rufus (mostly GPT mode for laptop after 2013, config autoselected by default in Rufus. Change to MBR if the pc is older),. Go in your USB key and enter the EFI and please notice the name of the files here.as grubx64.efi (unsecure boot) or shimx64.efi (secure boot). You will need this info later.
Restart the PC with the USB plugged in. When the Dell logo appears, hit F12 till you see the boot menu. If you can see your USB key here, don't select it.
First, enter the BIOS by selecting bios setup. Go on Boot Sequence, you need to ensure the BIOS is set to UEFI, disable Legacy option ROMS and check that secure boot is enabled on the Secure Boot Enable line. Now the most important operation. Come back to Boot Sequence ( General menu on the left). click on Add Boot Option. The Add Boot Option window will pop up.
Type a name in the Boot Option Name text area ('Ubuntu', for example). Click the button to the left of the File Name text area. The EFI Boot Selection window will pop up. In the File System drop down menu choose FS0: and EFI. Then using the directories section, navigate until you can choose SHIMx64.EFI (for Ubuntu only - for other distros use grubx64.efi or grubx.efi if your PC is not amd64, anyway it will be named grubxxxxx.efi) in the Files section. A new boot option will now appear on the top and in the boot menu.
Boot Manager Efi File
Save and exit. The pc will now restart, when the Dell logo is coming, press F12 again, till the boot menu appears. Select the name you entered in the previous step (NOT the USB key). The GUI installer will come up and you can run it If it does not work for you exactly like this, try disabling secure boot in the BIOS. You don't say what tool you used to create your USB drive. This is a critical detail because not all boot programs are created equal. And usually work well for creating EFI-bootable media, but this varies somewhat from one computer to another, so even if you used one of those you might try something else.

Another option is to install in BIOS/CSM/legacy mode and then install my from Windows. This will require that Secure Boot be disabled, but once rEFInd is up and running, it should enable you to boot Ubuntu.
Windows 8 introduces a new requirement for PC manufacturers (OEMs) that may require modifications to your OS deployment infrastructure. That requirement ensures that all Windows 8 systems are shipped with their BIOS in UEFI Mode and Secure Boot enabled.
Note: For a background on UEFI read this. Note: For specific information on deploying UEFI systems with Configuration Manager 2012 SP1, read the whitepaper by Chris Minaugh from Dell IT. This is a good thing, as UEFI mode removes hardware limitations that were present with Legacy Mode and adds greater functionality, while Secure Boot ensures that the boot loader is verified and has not been impacted by malware or rootkits.
Please read the that gives the full background for Secure Boot and specifies the OEM requirement. Most customers are using Legacy mode on their client systems even if UEFI mode is available so here are some steps to prepare for UEFI and Secure Boot enabled Windows 8 systems. Evaluate - The following areas of your infrastructure could be impacted by UEFI/Secure boot enabled Windows 8 systems. Review your current environment and evaluate whether UEFI/Secure boot enabled systems will require a change to your:. BIOS configuration. CCTK and OMCI can configure both UEFI and Legacy modes, but you should test against a UEFI/Secure Boot enabled system to validate your current BIOS configuration.
HDD configuration. UEFI Mode requires GPT partitions which are different from Legacy Mode/MBR partitions. Security tools. Review your HDD encryption and other security tools for compatibility.
OS Deployment Tools. KACE, MDT, and ConfigMgr will support Windows 8 but may require you to install the latest version (ConfigMgr 2012 SP1 for example) to be able to deploy Windows 8 on a UEFI/Secure Boot enabled system. Boot methods. WinPE 4.0 (available in the ADK) is required to deploy to UEFI enabled systems. The latest Mass Storage controller drivers may be required. UEFI PXE is also required and is different from Legacy PXE.
Plan - After identifying areas of your infrastructure that require changes to support UEFI/Secure Boot enabled systems, create a plan to make those modification and identify steps to continue with your current environment until those modifications are made. Test and Implement - Test the required modifications in your lab environment to ensure that they meet your requirements before deploying into production. Once your infrastructure is ready to deploy Windows 8 on UEFI/Secure Boot enabled systems, then you will be ready to take delivery of OEM delivered Windows 8 systems. Damian marley halfway tree zip.
