BIOS Update Wipes GRUB…"},"content":{"rendered":"

This might be the “new normal” with UEFI BIOSes but when I updated the BIOS of my IdeaPad Y50 the GRUB2 boot manager was gone and replaced by Windows 10’s boot loader.<\/p>\n

Even the upgrade from Windows 8.1 to 10 didn’t mess with GRUB. (Kudo’s Microsoft – Credit where credit is due!)<\/p>\n

Don’t have a cow, man!<\/strong><\/p>\n

It was, of course fixed by booting to Linux Mint 17.2 LiveCD. Unfortunately, I\u00a0still<\/strong> cannot get the “normal” GRUB fix to work. You know:<\/p>\n

sudo mount \/dev\/sda1 \/mnt\nsudo chroot \/mnt\nsudo update-grub2<\/code><\/pre>\n
Which gives the error:<\/p>\n
\/usr\/sbin\/grub-probe:error:failed to get canonical path of \/cow.\n<\/code><\/pre>\n
 <\/p>\n
Much Googling… Many hits on “I have the same problem…”<\/p>\n
The easy fix? Use Boot-Repair. It isn’t included in the LiveCD so you have to download it with:<\/p>\n
sudo add-apt-repository ppa:yannubuntu\/boot-repair\n<\/span>sudo apt-get update\n<\/span>sudo apt-get install -y boot-repair && boot-repair<\/pre>\n
I ended up having to clean up GRUB – how many different entries CAN it find? All of them, apparently. But, this is better than having to do a re-install….<\/p>\n
