Is dual boot with Windows 10 working without problems?

[jiri vesely]

I am using Windows 10 and i can't use Ubuntu, because you have to disable all disks, except disk: you are installing onto in BIOS! Otherwise you won't be able to boot up. And can't do that in my BIOS! I thought perhaps Debian may have the same issue... Can i just install Debian to another disk and than choose boot record in boot menu . Or if it installs bootloader, that would be okay too. I am just asking, if there are any common issues, before i install... Also is this distro private, i am not looking for some complex distro for privacy. But it shouldn't spy on users, or log ips you are connected to etc.

Thanks for answer!
