context: uefi, GRUB, BIOS
I have a Pavilion Power CB015 laptop. I want to modify the BIOS boot option label. Currently I have a windows 10 on the first hard drive (sda) and an Ubuntu 18 on the second hard drive (sdb). But in my Bios boot menu, the option is showed as Ubuntu on sda but not Ubuntu on sdb.
@ I can change the names in GRUB menu by using GRUB Customizer but I don't know how to change the name in Bios menu. It happens when I installed the new Ubuntu 18 on the sdb and deleted the old Ubuntu 16 which located on sda.
