I've never had an issue, outside of bios updates (see last paragraph). I've even booted into windows after hibernating in linux (but not the other way around, since I don't let windows hibernate; not saying you can't, just that I don't), and everything was fine when i got back. I use a swap partition for hibernating, in case you're curious.

I do try to make sure I'm watching when it reboots after a windows update (because linux is my default, so i have to select windows from the boot loader) just in case, but i've also fucked that up a time or two with no ill effects.

My one piece of advice is: once you get it working, take a picture of your bios settings. You may have to fix some settinga after bios updates, as they can get set back to the default values. I did not do this, and while it led to a very confusing afternoon due to my inexperience, it would have been a non-issue if I'd have taken some pictures and known to look at them.
