Unhappy on dualboot no option to boot linux, just straight to windows 8.


On a new laptop with windows 8.1 I installed Linux Mint Cinnamon. Now when I boot the system, no option to boot Linux comes up, it just goes straight to windows.

When I boot with the linux cd and try to install again, the install options says "you have multiple operating systems installed" and not "you have windows 8 installed" like in this screen shot

So I guess linux is installed.

But when I check windows > config > system > advanced > settings > startup > edit windows 8 can only see 1 OS (itself).

I had a problem with the driver for nvdia graphics, so I installed in compatibility mode. As described here http://forums.linuxmint.com/viewtopic.php?f=46&t=122257. Not sure that has anything to do with it.

After hours of googling I found this page:
https://sites.google.com/site/easyli...roject/windows
http://www.everydaylinuxuser.com/201...e-windows.html
(there really should be a link to this info from the installer at the double boot installation option!)
"Disable secure boot"
I can't find those settings in my bios at all. So unfortunately I am going nowhere with this fast.

So I installed Linux Mint and did not do the bios-adjustment first. How to procede? Do I need to uninstall linux first? If so, how?

IMHO is a bootloader problem...try to reinstall the bootloader that your distro provides...

I hear with Windows 8 it is easier to use Windows bootloader to chainload Linux bootloader. I have no experience with this, though, last Windows in my household had BSOD in 2003.

Sadly, you're right. Windows boot loader doesn't take note that Linux is installed while the Linux one does. Basically; Windows doesn't fancy linux but Linux doesn't give a shit - just work

Coming back to your problem:

Did you install Linux on a the same hard disk as Windows or you used another one?
You may have to fire up linux live cd again and install grub into master boot record. Hapilly, there are plenty of guides on it, so there is a solution

There are several options to do this but since you have Mint installed already you should follow this link below:

http://www.rodsbooks.com/refind/

I was having the same issue months back but after following this guide I can successfully dual boot Windows 8.1 & Slackware, until my girlfriend destroyed my laptop Now back to the old drawing board for me.

It is pretty detailed but it works just follow the steps.

I used the same HDD it was a Toshiba laptop with just one drive, but the same can be done if you wanted to have them on seperate drives. Just a matter of choosing the appropriate location accordingly during configuration.

I searched for "how to install grub into master boot record?" and went through the first 2 pages of the searchresults but all seem way over my head.

So I tried with the cd to reinstall grub to the mbr. But failed...

cow? Did something get lost in translation there?

Meanwhile I still did not manage to find that setting in my bios to disable 'secure boot'.
Could this have somthing to do with that?

Did you follow the given guide on a Mac PC/Laptop? I can see it's about UEFI so if it was a Mac which support it it must have worked.
In carsten888 case, we may be dealing with a normal PC which supports BIOS and needs a normal boootloader like GRUB 2 for example.
Anyway. I wonder what is your conclusion about the guide being MINT-driven based on. AFAIK - Such distro doesn't differ from the others in terms of boot components. Can you support your statement please?

Can you show us your current partitions state?
Quote:
sudo fdisk -l
should do the trick
Also. Check what your BIOS version is so we know if we're dealing with UEFI or not.

Try this. https://help.ubuntu.com/community/Boot-Repair http://www.rodsbooks.com/efi-bootloaders/ http://bootinfoscript.sourceforge.net/
If you can't get it to work with the boot-repair post the results of the bootinfo script

I said it was a Toshiba laptop so that is PC not MAC. The "refind" guide that I posted has details for either platform: PC (windows & linux) plus MAC as well. Since UEFI bios is disabled (based on that screenshot) i believe secure boot is automatically disabled as well but don't quote me on that one. I recommend you follow those steps from the link I posted earlier in order to achieve dual boot because it works. Just take your time & have a little patience & it will all come together.

I downloaded the cd image from http://www.rodsbooks.com/refind/getting.html and booted with it. It went straight to win8 again. If I put a linux cd in there it boots from there, so I can only assume it was booting from the iso on the cd and it didn't work.

Downloading the LiveCD alone isn't enough to solve this issue. There are commands and procedures that need to be entered in order to boot Linux 1st or even have the choice of booting other installed OS's.

I used the LiveCD as a tool in order to manipulate some of the boot files already installed in order to get the laptop to recognize both OS's. After following this procedure the LiveCD isn't needed.
