I have 2 Hard disks.
first = Windows XP, Windows XP64 second = Linux Mint 17.3, Windows 7
I want to install Linux Mint 19.1 over the old Mint 17.3
The system boots with: Linux Mint (default) Second option Windows 7
If I select Windows 7, it goes to another bootloader, where appears: Windows 7 Older Windows
If I select Older Windows, it goes to WinXP and WinXP64.
Foormatting only Linux, where is the bootloader that I have to keep?
