![]() The new media also ignores my keyboard and I can't edit my kernel parameters, so that's an improvement. I downloaded both cds, and they also suffer from the same issue. Does "simple" really means that I need to use others distros just to install Arch properly? I know Arch is know by "simple, lightweight distribution". Isn't there a way to boot the media in UEFI? Really, any good distro nowadays allows it, and if I'm correct, previous Arch's ISOs allowed too. setting it from Windows if you dual boot or using the EFI shell) but these are the two I've used myself and I think they are probably the simplest options. Once you are booted into your new install in EFI mode, you can then set the nvram entry. If you use something like rEFInd, you'd also need to copy the files it expects to find in its own directory but for something like grub, you just need to copy the. So for example, you would copy grub圆4.efi there or whatever you use. Normally this would be EFI/boot/boot圆4.efi on your ESP. There are at least 2 ways to do this if you can't boot the installation media in EFI mode:ġ) Use any live linux distro which will boot in EFI mode, follow the wiki instructions for setting up a chroot, chroot into your Arch installation, set the entryĢ) Copy your EFI boot loader or manager to the default/fallback position. You can install for EFI while booted in BIOS mode except for setting the nvram entry. The media boots fine in BIOS ("legacy") mode, but I'd rather try making it work with UEFI before resorting to BIOS. This only happens with Arch, although I'm not sure any of the other distros I've tested use this bootloader.ĭoes anyone have any suggestions I could try? Can I boot to the installer using elilo, which works fine and is already installed on my ESP? If yes, how? (the system uses a nvidia card) My motherboard uses the latest BIOS/UEFI but Arch had this problem before I updated too. I've tried the recommendations described in the Beginner's Guide e.g. The screen doesn't fall asleep, it just stays blank. It boots fine, presents the menu with the boot options, but after I make my choice (or wait for the default) the screen goes blank, the cd is active for a bit, and then nothing happens. ![]() If you have a recovery partition, to boot directly into the Recovery Mode, turn on the Mac and immediately press and hold ⌘ + R.Is it possible to install Arch with UEFI enabled? Since the switch to gummieboot (?) it is impossible for me to get the installation media to work. The ambiguity of that last statement is I did that awhile before writing this comment, and I don't recall what I booted into first, only that it worked and was not hard to figure out what to do at that point. Installation will continue, or you will boot into the OS or get the Recovery Utilities menu (where macOS can be reinstalled from or Disk Utilities run). If the recovery partition isn't present and valid, these instructions won't work.Ĭlick the second entry. If the second partition isn't the recovery partition, look under the paths in the list to see if one of them is it. The second PCI path is probably to the recovery partition, the one you need to boot from. The first PCI path in the list is probably the boot partition that doesn't contain bootable firmware. You should see two entries in a list (they are cryptic-looking PCI bus paths). Select Boot Maintenance Manager and click. You'll be brought into an EFI text-mode GUI. I was able to fix the UEFI problems as follows (credit to the VirtualBox forum): After manually directing EFI to boot into macOS for the first time, macOS automatically fixed up the boot partition, and subsequent boots worked properly. In my case, after installing macOS into a virtual machine according to these instructions (running the macOS installer from an ISO image downloaded from Apple), on first boot, the boot partition was present, but unconfigured (probably no boot image installed). ![]() By now you may have surmised boot.efi is an EFI standard filename that lives at an EFI standard path in a disk partition, and it contains OS-specific boot firmware (e.g., Windows, Linux, etc. Ultimately, the objective is provide a boot partition that contains a macOS boot.efi. Your immediate objective is to help EFI locate and execute OS-specific boot firmware. However, assuming you have a macOS recovery partition on that disk, it should contain a copy of boot.efi (macOS-specific boot firmware) that you can boot into the OS with. UEFI requires intervention, because the EFI firmware on the Mac's motherboard can’t find valid OS-specific EFI boot firmware in the standard location on disk.
