I recently installed Ubuntu alongside Windows 8. Then used Boot Repair and all was fine.The Grub boot loader showed-up and had an option to boot Ubuntu or Windows. Then I booted into windows. Everything looked fine until I rebooted. After I rebooted there was just a black screen with some text saying:

No boot device available 
SATA 0: Installed 
SATA 1: Installed 
SATA 2: None
SATA 3: None
Strike the F1 key to retry boot, F2 to run setup utility

When I hit the F2 key it takes me to the BIOS setup where i see that it is trying to use the Windows Boot Manager instead of the Ubuntu Boot Manager.

I am not sure what i can do here, if it is of any use i do have both a Ubuntu installation disk and a Windows installation disk. Oh and the Bootinfo link from running Boot Repair is http://paste.ubuntu.com/6536548/

Thanks in advance for your help.

Run Boot-Repair, but when asked "Do you want to activate [Backup and rename Windows EFI files]?", answer No. Then in your BIOS (UEFI firmware), set Ubuntu as default entry.

Now using Windows should not mess up the boot any more.

So i will have to re-install Ubuntu so i can get to a terminal, and then run the Boot Repair command. –  wisaac407 Dec 8 '13 at 23:49
    
No, you just need to run Boot-repair from a live disk. See help.ubuntu.com/community/Boot-Repair#Getting_Boot-Repair –  LovinBuntu Dec 9 '13 at 1:07
    
I tried that, and it sort-of worked... Windows Boot Manager is still the only entry in the BIOS, but it works now. –  wisaac407 Dec 12 '13 at 20:28
    
Forgot to mention the Boot Info link. Here it is. –  wisaac407 Dec 12 '13 at 20:37
