I have a problem when I installed Ubuntu 18.04 LTS as secondary OS. I used windows 10 before and I want to make dual boot with Ubuntu 18.04 LTS. I already create 30GB free space on the disk and I already make USB boot too. I followed the steps to install Ubuntu and make one partition as swap and one as ext partition. I used "Something else" method in this case. But, when I installed it works well in the first copying and installing but when Grub2 package installed I have some error said like this :
I used HP laptop with 4GB RAM and I used windows 10 to make free space of partition. I also use rufus to make bootable from USB device.
Anyone please help me to solve this problem. Thanks before.
