By - revision 20 Dual booting Windows with Mac? abbyy linux serial console Getting duplicate “Windows Boot Manager” boot entries appearing on every boot? Is your ASUS BIOS sometimes completely freezing on boot due to these boot entries building up (what a dumb bug!)? Eventually I got pretty fed up of unplugging every non-boot hard drive just to unfreeze the boot sequence, so I ventured to find a solution. After much research (there is a good ) this is my write-up on the solution. here goes! The summary: Rename the Windows EFI bootloaders to something else, so that the BIOS doesn’t see them. The set up: I have a SSD for each Windows and Mac. I’ve placed the EFI bootloaders for both Windows and Mac on a singleEFI system partition (EFS). Download Clover EFI bootloader for free. Boot OS X, Windows, and Linux on Mac or PC with UEFI or BIOS firmware. If you are unable to configure correctly please visit https://sourceforge.net/p/cloverefiboot/discussion/. UPDATED with r1242 files, Installer & ISOThis is EFI-based bootloader for BIOS-based computers created as a replacement to EDK2/Duet bootloader http://ww. In my case, this is the EFS of the Windows SSD drive. Disk #1: ``EFI (Clover bootloader as default, Windows bootloader) + Windows NTFS`` Disk #2: ``EFI (leave empty, don't use) + macOS HFS`` Keeping all bootloaders on a single EFS seems to help prevent the issue. Drawbacks: There are some drawbacks with this method. Whenever you wish to run. • the “bcdedit“ Windows utility / make changes to the Windows bootloader, or • run Windows Memory Diagnostics you’ll first need to restore the Microsoft folders back temporarily. Afterwards, you would want to rename it back. Be prepared to get your hands dirty with UEFI bootloaders! Step 1 – Boot into OS X, mount the EFI partition mkdir /Volumes/EFI/ mount -t msdos /dev/diskXs1 /Volumes/EFI/ Fun fact: If 'for some reason' the partition identifier (number) of your EFI partition is not numer 1, you can use ``fdisk`` to ``fix`` the partition order. Step 2 – Rename Windows boot directories It appears that the AMI Aptio BIOS (or at least, this ASUS Z97K CSM mobo) is hardcoded to search for the EFI/Microsoft/Boot/bootmgfw.efi path, which is causing the redundant entries – Grrr! Rename the Microsoft part to something else – I just prefixed it with MS. Pro-tip: We want to keep the Windows EFI files as-is, as it contains BCD boot stuff, which can be to restore. I didn't find any good FREE Java books on concurrency and multithreading, which I really wanted to include. Though books like or are not free, they are worth of every penny spent. If you come across genuine FREE multithreading books for Java programmer, then please let us know. The lilliebridge method. Next, we should also deal with of the EFI/BOOT directory. I also prefixed it with MS- just in case I ever want to revert from my Hackintosh set up. Warning: Whenever you wish to run bcdedit from Windows, or run Windows Memory Diagnostics, you’ll first need to restore the Microsoft folders back temporarily, then afterwards rename it back. Step 3 – Install Clover EFI files Download the latest and mount the ISO. Copy the BOOT and CLOVER folders over to your EFI partition. You should now end up the following: At this point, re-configure your Clover config.plist, kexts, and drivers64UEFI. Copy a backup from USB (highly recommended to have one). Clover Efi Boot Loader For Windows![]() Clover Bootloader IsoFollow a guide if you don’t know how. Fact: When we replaced the BOOT directory, we replaced the default boot loader for the drive. Step 4 – Create custom boot entries Make sure you have the latest version of. (Fetching partition UUID’s was recently added!) File > Open > navigate to your config.plist Under the Gui section, create a new Custom Entry with the following: • Volume – Select the EFI partition that we’ve been working on (from Step 1). Clover Bootloader Usb WindowsThe UUID automagically appears — hooray time saved! • Path – Use your new custom path, e.g. `EFI/MS-Microsoft/Boot/bootmgfw.efi` • Type – Set to Windows • Everything else is probably optional Similarly, repeat for your Mac partition. Unlike my screenshot, keep Scan Auto=Yes for the next step (or the UEFI Shell boot item won’t show up). You can turn it off after everything works. Step 5 – Purge all boot entries Reboot. Clover should boot! Select UEFI Shell: Run this command: dmpstore -d Bo* Run this command: dmpstore -d Boot0* and then dmpstore -d BootOrder This will clear the BootOrder and any other Boot entries from the EFI NVRAM. That’s what you want, right? Alternative method: Conclusion By circumventing the hard-coded search paths in the UEFI firmware, we prevented the firmware from erroneously adding a “Windows Boot Manager” boot entry on every boot, thus preventing the scenario of the firmware freezing/hanging on boot due to too many entries. AsRock users: If, after rebooting, no Clover doesn’t start, you need to boot into a copy of Clover on a USB to run: bcfg boot add 0 fsX: EFI BOOT BOOTX64.EFI 'My Clover UEFI boot entry' from the UEFI shell, where fsX is your EFI partition. Figure out which fs0, fs1, etc. It is using the ls command. Post navigation. It contain colored illustrations and image based questions. It also have important Annexure notes with latest TNM staging.
