I installed Ubuntu 3 years ago and an upgrade attempt failed. The disk was configured dual-boot with Ubuntu + Windows.
I tried to install an ISO file for Ubuntu 16.
How can upgrade my previous Ubuntu installation to Ubuntu 16 without losing the dual-boot or Windows!?
my ubuntu version is so old I think Ubuntu 9.04 (Jaunty Jackalope) or maybe before
ok if I do those steps what about the boot loader do I have to make it as the old times?
