Hello, I am currently running windows 8.1 and im planning to upgrade to win 10 but i have read that there is an issue when upgrading to win 10 with dual partitions from a single hdd (essencially the secondary partition gets wiped out clean and connected back to a single one partition). So have any of you experienced such an issue? And what would be a possible fix, because i have alot of stuff in my secondary partition and i do not want it to be wiped out?
