Clover bootloader failed to install or boot : how & why (not for beginners)
Most frustrated situations using Clover bootloader are failed to boot, which caused from the installation failure even though you've been using Clover bootloader without issues.
1. Fail to boot with Clover bootloader: Whatever the reason why, In this case, you need to create a bootable USB of Clover bootloader under Windows environment, and the most easy way of doing this is done by BDUtility:
BDUtility formats the USB and install the latest Clover bootloader by itself. No other easy way to do it under Windows.
After booting with new created USB by BDUtility, you can select the existing partition booted successfully before. Once you boot into that mac partition with USB booting, then you have to install Clover bootloader again into the specific booting partition with fine tunings of parameters.
Of course, you should be familiar with changing boot sequence in BIOS to change booting sequence into new USB to boot at first.
2. Installation failure of Clover bootloader: you should check if EFI partition is filled with backups of previous versions. No space to install would cause the installation failure but no specific reason why failed in the screen. Please delete backup of previous Clover bootloader except for the last one. You can see the sample screen capture that only r3949 is left and all other backups are deleted below:
These are based on the assumption you're in trouble after installing new version of Clover bootloader. Please refer this URL if you are new to Clover bootloader:
