百度在这方面一直不给力,而google最近又被和谐的厉害,最后借助 ask.com 找到下面办法:
Use Boot Repair to fix your bootloader.
- Boot Ubuntu from a LiveCD or Live USB (可以通过 ubuntu usb 启动盘)
- Connect to the internet
-
Open a terminal, and add the Boot Repair PPA
sudo add-apt-repository ppa:yannubuntu/boot-repair && sudo apt-get update
-
Install Boot Repair
sudo apt-get install -y boot-repair &&
(boot-repair &) -
Launch and use, see https://help.ubuntu.com/community/Boot-Repair#Using_Boot-Repair for more details
sudo add-apt-repository ppa:yannubuntu/boot-repair sudo sed 's/trusty/saucy/g' -i /etc/apt/sources.list.d/yannubuntu-boot-repair-trusty.list sudo apt-get update sudo apt-get install -y boot-repair && (boot-repair &)
Advanced options
Warning: the default settings are the ones used by the "Recommended Repair". Changing them may worsen your problem. Don't modify them before creating a BootInfo URL, and asking advice on this thread.
