Hi, I am currently dual-booting Ubuntu 15.10 and Windows 7.

 

I read somewhere that if I re-install/ clean install/ upgrade Windows, I will lose GRUB, and it will be replaced by Windows' own bootloader.

 

So, please give me a detailed explanation of how to re-install GRUB if I re-install Windows.


Usually, I do not get online before 1:00 PM or after 10:00 PM (my local time).

 

So, if I do not reply to a thread where I am currently active, make sure you check my local time to see if it's time for me to be online or not. :)

Thanks, Nick. :)

 

EDIT: I need to ask something.

 

The guide that you mentioned says this:

 

 

Mount the partition your Ubuntu Installation is on.

 

Does that mean the root (/) partition?

normally yes, usually reinstalling grub is rather easy.

The only trouble I see is if your machine uses uefi


You know you want me baby!
