I have installed Windows 10, CentOS 7 X8 and Ubuntu 16.04 in the same order on a laptop.
Now on the Grub menu does not recognize my CentOS. I can only boot to Ubuntu and Windows.
I would appreciate if someone could help me to edit my grub2 in Ubuntu 16.04
Here are my partitions:
jeff@PC2U:~$ sudo lsblk -o NAME,FSTYPE,SIZE,MOUNTPOINT,LABEL
NAME FSTYPE SIZE MOUNTPOINT LABEL
loop1 squashfs 135,5M /snap/gimp/30
sr0 1024M
loop2 squashfs 81,6M /snap/core/4110
loop0 squashfs 86,8M /snap/keepassxc/30
sda 111,8G
├─sda4 1K
├─sda2 ntfs 50,3G (Windows)
├─sda7 ext4 32,6G / (Ubuntu 16.04)
├─sda5 crypto_LUKS 18,6G (CentOS 7 - / (root))
├─sda3 ext4 476M (CentOS 7 - /boot)
├─sda1 ntfs 549M System Reserved (Win7 recovery part.)
└─sda6 crypto_LUKS 9,3G (CentOS 7 - /home)
