Bootloader does not load [closed]

[Kaylabyte]

Bootloader does not load after installing Manjaro KDE alongside Windows 10.

During installation, set /boot/efi as the boot partition with 512 MB space with FAT32 format, and set / as root partition with 199488 MB with ext4 format.

After installing, no bootloader comes up, and it boots directly into Windows 10.

After installing, it is also no longer possible to get into the BIOS (the computer freezes on the manufacturer’s logo).

Not sure if this is relevant, but the installation is on an Acer Aspire 5 laptop.

How can the bootloader be restored, or this problem be diagnosed?

Thanks in advance for your help and suggestions.

EDIT
In the end, I just bought a replacement computer.
Thanks to everyone who offered help!

As I said, I cannot access the BIOS. So I currently can’t change the BIOS sections you are suggesting I change.

Which bootloader did you use
