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.

Picture for Reference enter image description here

Thank you.

  • why do you think sda is named dedicated for Windows10? when you have multiple disks the system decides what to call. when it is showing ubuntu on sda, have you tried to read for "windows boot manager on sdb" in grub menu selection window? – PRATAP Jan 11 at 7:25
  • In Bios menu I have Ubuntu on sda or Windows boot manager on sda. – Anh-Tuan Mai Jan 12 at 12:07

    changing of the name in BIOS -> Boot Option menu is purely dependent on the BIOS vendor, i dont think such facility is provided by the vendors. if worked out well, may be the text "ubuntu" can be possible but not the format <KXG50ZNV256G TOSHIBA> if you want to see Ubuntu option on Other Drive name, you need to Install EFI System Partition on that drive. – PRATAP Jan 12 at 13:16

    if you decided to create a separate EFI System Partition for Ubuntu on other drive, this may help askubuntu.com/a/1076535/739431 – PRATAP Jan 12 at 13:18
