Re: [SLL] Help with dual boot setup

[Tim Thomas]

Hi Randyl,
I want to make sure I understand correctly. 
Problem:When you boot up there is not a menu selection to choose Linux. 

I have done this before with windows 10 and CentOS. When I did, I chose to 
install and use GRUB as the boot loader. I think if you do that you will have a 
lot easier time configuring it to use a particular default or manually select 
the OS on boot up.
But... I just went and read some SUSE documentation and it says it will not 
install GRUB on machine with UEFI unless Compatibility Support Module (CSM) is 
enable.
Here is where I got that:
https://www.suse.com/documentation/sled11/book_sle_admin/data/cha_grub.html


If this was me, I think I would make sure I have CSM and then install SUSE 
again and choose to put in on the MBR (I hope I have the term correctly used).
I think trying to make the widows boot loader do it will be too much of a 
headache.

Dear old Linux List,
I'm so glad you are still here, and I hate to come across like a complete
newby, but I need help getting a new machine with preinstalled Win10 to get
dual boot to work.
Background:
 1. Last month my old linux box crashed, refused to boot, hard drive
corrupted.
 2. Bought an HP Pavilion 550-227c desktop at Costco with Win10 Home
installed on 2TB drive. Everything works as it should.
 3. Installed openSUSE Leap 42.1, resized windows partition, all the
default linux partitions for swap, boot, root, etc. Everything works as it
should except sound (RealTek HD, missing special driver maybe?).
 4. Rebooted into Win10 and everything there still seems to work, except .
. .
 5. There is no option or opportunity to reboot into Linux that I can find.
 6. So obviously I don't know wtf I'm doing and now I'm trying to learn
more than I ever wanted to know about UEFI and new secure boot process.
 7. Costco Tech Support was no help and handed me off to Microsoft, which
was even worse.
 8. I did figure out how to run bcdedit (boot config data editor) in
windows, but I still don't know how to get a boot menu so a linux boot is
an option. I do know the linux installation is still there, so I could, if
necessary, reinstall linux, but rather not.
Help? In Seattle, I hope?
Thanks,
Randyl

Dear Randyl,

Would love nothing more than to help you, but... I have no idea how
Windows 10 works, in older versions of windows you could boot up
from an install/repair disk - open a console (cmd) and then try using 
a program called Bootrec (bootrec.exe /fixmb ) later versions of
Windows you can start up in "safe mode" and then run console - same
procedure...

this is a good link for the process:

I really hope that this helps you :)
