Refind shows up without any option (hangs) This should rebuild your EFI partition and you should be able to boot into Windows now. To format and rebuild the partition, boot into your Windows 10 media (I hope you have one), launch a command prompt and execute the following: mountvol B: /s format B: /FS:FAT32 bcdboot C:\Windows /s B: /f UEFI Note that this will only work if Windows is the only operating system installed in this partition. I usually just format the partition and ask Windows to rebuild it, this way you should have a fresh start. This probably happened to me a few dozen times in the process of trying to install refind.Īll you have to do is fix your EFI partition. Troubleshooting I messed things up and now I can’t boot my computer Since we manually added the Windows entry to refind, you should be able to boot into Windows from there. Next time you boot your firmware should not find Windows Boot Manager and fallback to refind. Close the command prompt and restart your computer. Alternately, open the Mac App Store Preview page for macOS Catalina here then select View in Mac App Store.In this blog post I’ll be covering the process of installing and troubleshooting refind bootloader from a machine running Wind(although I hope this will survive any updates from Microsoft).Īt first, I tried following the official documentation and replacing the Īnd that’s it. Go to the Mac App Store and search for Catalina using the search bar, then click on View next to the macOS Catalina listing. This is an unavoidable part of the process and will require just over 8 gigabytes of drive capacity to store.
The first hurdle is to actually get the macOS Catalina installer onto a Mac. However, it is still possible to create your own media, such as a spare USB thumb drive, that can do the same job. While in the olden days it was possible to get the software update on physical media, Apple doesn't offer that option anymore.
The strain could also be felt by users who own multiple Macs but also have a limited data allowance from their Internet provider, or a small amount of bandwidth that could make updating multiple machines take a very long time and saturate the available connection. As Apple usually intends each Mac or MacBook needing to be updated to download it, the process isn't really efficient enough for instances where many Mac desktops need the upgrade, like in a school or business if there isn't device management or macOS Content Caching for whatever the reason.
One of the problems with the release of a major operating system update like macOS Catalina is the amount of times it has to be downloaded.
