I have an acer travel mate laptop with windows and I wanted to also have Ubuntu, so I downloaded the 22.04.3 image and used rufus to make a booteable USB. Then I proceed with the instalation in one of my hard drives, I have two (one for Windows and other for Ubuntu). I manually create the partitions /boot, swap, / and /home and everything is fine. Then I restart the laptop and instead of loading me into grub to select he required OS it keeps loading Windows 10. I thought that it was the boot priority in the BIOS and then I noticed it, the hard drive where I installed Ubuntu is not in the boot priority. My main drive (Windows) is the Gigabyte one and the Toshiba is for Ubuntu. Here is a picture:
How can I make recognizable the drive?
Edit
I have made some discoveries. If the bios mode is changed to legacy, the Toshiba disk appears in the boot priority list:
But it is not detected by the boot manager:
If the bios is in UEFI mode, the boot manager only detects the windows partition:
Also,I tried to reinstall ubuntu and this where the partitions detected:
You can see that the EFI partition is VFAT i don't know why because it was fat32 when I installed it for the firs time. And this is how I left it:
