The picture you posted doesn’t show an error, that’s a screen to select your boot drive. Are you saying you don’t know how to select a boot drive or that when you do select the boot drive, nothing happens? You’re not giving us any information to help you with.
ACPI errors shouldn’t be an issue, it’s somewhat common to see them. Are you still able to boot from live USB? Are your Linux and Windows installations on the same drive? Sometimes Windows can mess with the boot settings of other OSes and even break a GRUB install.
