自己配了一台台式机，在安装黑苹果后，每次开机在BIOS中就会新增一个启动项，电脑几天用下来都多出来几十个启动项。于是Google好久才找到解决办法。于是记录一下。

这是我在tonymacx86发帖的内容，就直接复制过来了，都读的懂。

Problem

Every time i restart my El Capitan osx i get another boot entry on bios.

Solution

not in windows but you can do it (as I did) under clover shell

Enter EFI Shell.
As shell loads, note the label of the HDD/SSD your efi and OS X are installed on. FS0 in my case. or type map to see it
Then bcfg boot dump.
VERY CAREFULLY add a new entry after the highest one in the list. I had to type bcfg boot add 05 FS0:\EFI\CLOVER\CLOVERX64.EFI CloverBoot w/o the quotes, where 05 was the new entry
Then you can delete old bcfg entry that pointed to /BOOT/BOOTX64.EFI with bcfg boot rm XX where XX is the number identifier seen when u do bcfg boot dump
Then, booted into OS X, mounted EFI, and renamed /BOOT to BOOT.bak
