Trying to install LMDE4 on laptop Lenovo Ideapad 110-15ibr

Trying to install Linux LMDE4 2021 on laptop Lenovo Ideapad 110-15ibr 2016 after replacing old HDD Samsung 1000GB with new Samsung SSD 120GB; I can only enter BIOS by pushing F1 which gives me the warning: EFI network0 for IPv4 (C8-5B-76-QA-CF-F4) boot failed!!! Please, could anybody tell me what I have to do now? Seems like I am locked out of booting... And yes, I've already been trying F1, F2, F12, and reset switch.
Any REAL help will be very much appreciated!
