Dual boot Windows 8.1 and Ubuntu issue....

[Slug71]

You should have a one time boot key that lets you choose which device to boot. I have 4 hard drives and do have different grubs installed in each. While I can boot everything from a grub menu, I let the very new install just default to install to sda and directly boot it with f12. My default and main working install is the sdd drive.

Thanks again oldfred,
Will press some buttons and have a look.

I am having this very same issue. Booting Windows 8.1 from GRUB causes the computer to simply restart and GRUB to load again. Win 8.1 will boot fine if you change the boot priority in BIOS however I don't want to do this every time I need to boot into Win 8.1. Has anyone solved this problem. I am a newbie to Linux/Ubuntu but I do have a moderate knowledge/skill with computers. Any help would be greatly appreciated...

If you have fastboot still turned on that can be an issue. For whatever reason grub cannot chainload to Windows when hibernated.
