Ok, so some people may have seen my previous post about wanting to dual boot Windows 8 and Ubuntu, and I did that, without wiping my hard drive. I then restarted hoping to access windows 8, however I booted straight into ubuntu. I went into the BIOS and straight away re-enabled the Secure Boot settings. It says there are no available boot devices. Now I can only boot into Ubuntu. Help.

You boot only into Ubuntu? No Grub?

Whilst in Ubuntu when you open a file manager do you see a separate drivce partition that you can open and see all the windows program files? If not then chances are you installed Ubuntu over it and maybe just imported files or something.

Yes, all the Windows program files are there. It's only the bootmgr.dll that is missing.

Sorry, I boot into GRUB and get a choice to boot to:
Ubuntu
Ubunu Advanced Options
Mem Test

Add Windows to GRUB. For some reason GRUB didn't detect it automatically. http://erickoo.wordpress.com/2009/06/14/how-to-add-vista-partition-to-grub-2-ubuntu-9-10-karmic-koala/

Make sure you find the right partition also, many times windows creates two partitions, a boot and the actual windows partition. You cannot boot the actual partition, so if you have a separate boot partition for windows, you have to point GRUB at that. It should be around 100MB in size (or something similar).

Check your grub-directorys. One of them has scripts in it in a particuliar form like "10_headers" and stuff. There should be a script like "10_os-prober", if there is no file with os-prober in it, than thats the reason your Windows isn't recognized, since this script is looking for active operating systems. Try 'sudo apt-get install os-prober' followed with 'sudo grub-update' and that should do it.

You could give the "easy way" a try too:

Boot into Ubuntu.

Open up Terminal (Ctrl+Alt+T).

Type:

Code:
sudo add-apt-repository ppa:yannubuntu/boot-repair && sudo apt-get update
Press Enter.

Then type:
Code:
sudo apt-get install -y boot-repair && boot-repair
Press Enter.

Now, launch "Boot Repair" from the Unity Dash, and hit recommended repair. Your problem should be fixed.

That's hardly much easier than the ways already described. Also, I prefer using aptitude CLI over apt-get. It's not much different these days, but it removes unused dependency packages when you remove a package and you don't need to remember half a dozen different names for apt-get to do various things.

I beg to differ really... There is a lot more "automagic" going on with those two commands than there would be with the above methods. You type two commands and then run a program.

How is that not easier than playing with GRUB settings if the guy is just starting out playing with Linux? I think that his initial impression likely isn't the greatest because of this little "hiccup". So telling him to add something to GRUB is something I doubt he wants to hear.


Additionally, apt-get will tell you what it will remove if it removes unneeded dependencies... It also warns you when there are packages that are no longer required and allows you to autoremove them. I hear you on the multiple apt names though like "apt-get", "apt-cache", or "apt-add-repository", etc... But I never had much of a problem with that.

It's not that hard to add like one line to GRUB that points at Windows manually.

Tried every single method offered in this thread now, and I can say with all honesty, none worked. So I guess I'm stuck with ubuntu. forever.

Hm... Well, what about this..?
Code:
sudo grub-install --recheck /dev/sda
sudo update-grub
This should re-run the detection process and hopefully detect your Windows partition...

Additionally, could you go to a terminal and post the output of the above commands and "df" here if that doesn't work?

You could copy/paste the terminal output here, you know. That way we'd actually be able to say where you went wrong.

Aha! There's your problem..!
I got you to type a command to detect OSes on your first hard drive, not your second.

Try:
Code:
sudo grub-install --recheck /dev/sdb
sudo update-grub

Normally that would work, but I'm pretty sure my "second hard drive" is my C: backup connected by USB.

That's some strange layout you have there. So I guess your partitions are as following:
/dev/sda Harddrive
/dev/sda1 Windows 8
/dev/sda2 Ubuntu

Normally there should be another layout (at least what I experienced)
/dev/sda Harddrive
/dev/sda1 Windows Bootloader
/dev/sda2 Windows 8
/dev/sda3 Ubuntu

Is 'sudo fdisk -l' showing you the above layout? if so, then maybe you somehow crashed/deleted your Windows Bootloader

If you want to be able to boot into your Ubuntu partition after doing a Windows recovery, you might be able to use EasyBCD to do it.

There's no easy way to make linux and windows 8 play nice, but one of these two options should help: http://www.neowin.net/news/two-windows-8-linux-boot-solutions-may-merge-efforts

Indeed..! Or, as much as so many people seem to hate it, Wubi is another option... It is the autorun on a Ubuntu or Linux Mint CD when you try to open in in Windows.

Shame we couldn't get a solution earlier to you though. Blech.
