Hackbgrt151 High Quality [iPhone]

Here’s what I can tell you based on the phrasing:

After saving, run sudo update-grub and reboot. The new entry should now launch Windows through HackBGRT, making your custom logo appear once again.

# Preferred resolution. Use 0x0 for maximum and -1x-1 for original. resolution=0x0 Use code with caution. hackbgrt151 high quality

When a computer boots up in UEFI mode, the motherboard displays a hardcoded manufacturer logo (like ASUS, Dell, or HP), which Windows later pairs with its spinning loading dots. HackBGRT alters the in your system's ACPI firmware on the fly. Here’s what I can tell you based on
