As this is a fresh installation, why don't you just wipe everything linux partitions and install again the way you want it. Alternatively boot into a usb or live cd or installer, mount the volumes and chroot into (there are many howtos) I use something like following where SYSTEM is the target ppath mount --make-unbindable -obind /proc/ $SYSTEM/proc/ && \ mount --make-unbindable -obind /dev/ $SYSTEM/dev/ && \ mount --make-unbindable -obind /dev/pts $SYSTEM/dev/pts && \ mount --make-unbindable -obind /run $SYSTEM/run && \ mount --make-unbindable -obind /sys $SYSTEM/sys/ && \ chroot $SYSTEM su - when you are there reinstall grub and run update-grub I hope this helps
