5 times now, i have tried different things. Ive formatted the space im using for my linux install, ive downloaded a new iso, everything. Every single time i try to install Linux Mint 19, i get error "The 'grub-efi-amd64-signed' package failed to install into /target/. Without the GRUB bootloader, the installed system will not boot." I am now *extremely* aggravated, as ive done everything people have said to fix this. Is there any other option, other than formatting my harddrive? Earlier today i had to clear suspected corruption on my windows 10 install with "chkdsk" and it came out totally fine. I can now shrink volumes and interact with my disk manager, and i thought i was fine to install linux on a COMPLETELY CLEAN drive, but for some reason i keep getting this error message.
