I'm at my wits end. I'm trying to get my dual boot system running how I want it for a while now ever so often it just doesn't post anymore. Fans spin, boot light on but nothing else. I can remove every additional drive and device connected and it doesn't boot.
What always fixes it is disconnecting the power and pressing the power button a bunch of times, then trying again.
But I'm just stumbling in the dark, I wish I knew more about this side of things.
I did the thing you shouldn't do that is installing Linux first then Windows on a second drive. I dread to format everything and try again but I might just have to do that...
