Or why mess with partitions at all. Based on this dual boot comment I decided to give the Win10 upgrade another try. So far (knock on wood) I’ve not run into any of the issues from my previous upgrade attempt. So I just might be joining the modern world.
But rather than messing with a partition I just cloned my system disk to a new larger SSD, changed the boot order in the BIOS and now the new disk is on Win10. If I want to get Win7 I can in the boot. But I’m not really interested in jumping back and forth between OS, just in being able to boot into a stable OS (which was a big problem last time). Once I’m sure Win10 is OK the old disk can be repurposed for sample libraries.
Was quite surprised at how cheap SSD’s are going for now. I noticed a disk that I bought one year ago, exact same disk now costs half of what it did then.
