hello, i have been using Linux mint for awhile, and recently i upgraded one of my laptops to 4.0 standard.
during the installation, the installer crashed. grub install error. now i cant boot to a disk, and when the grub starts, i get error 15.
what can i do to fix this, or wipe my hard drive.
if worst comes to worst, ill buy an external hdd case for laptop hard drives and hook it up to my desktop to reformat. is there any other options?
i tried boot disks:
and usb thumb drive linux (Mint portable).
