When duo booting windows 10 and kubuntu why is the bootloader installed in the windows partition?

[mrchow19910319]

I have been trying to make my laptop duoboot with windows and Kubuntu.

 

Now I have these partition in my boot list: 

 

1. windows boot manager (in windows SSD)

 

2. Ubuntu (in Linux SSD)

 

3. Ubuntu (in windows SSD)

 

if I boot into 3, the system boots.

if I boot into 2, I get this error :

is this normal??

It's probably just a quirk of how your motherboard detects bootable drives. It's not inherently a problem but, from the way you described it, it seems as though you installed grub in the windows boot sector - Windows sometimes overwrites that when updating, meaning you could lose access to your Linux system. I'd reinstall Kubuntu and tell it to install the bootloader in its own drive.

I am planning to wipe out both of my SSD and just do a clean reinstall.

 

Maybe this time I can do these just to prevent the GRUB bootloader got installed in the wrong place: 

 

install windows 10 

 

disconnect windows 10 drive

 

install linux 

 

reconnect windows 10 drive.

 

is this a better way to duoboot linux?

Yeah, that should work fine.
