By now I use SSD 240GB with Windows 7 and Ubuntu 18.04 LTS. When I power on my computer it starts Grub and ask which SO I wanna to open. My motherboard is a Asus H110 Plus. Grub is installed ad MBR. To do it I always formar my SSD using a live CD creating a: NTFS + EXT4 + SWAP partition. So I install Windows 7. And after I install Ubuntu that recognizes automatically both systems.
By now I download Ubuntu 20.04 and make same procediment as I said above. I installed Windows 7 on a NTFS. So when I was installing Ubuntu showed a messaged: "I should define a EFI partition".
I make it because I created a: #1: SDA1-FAT32 100MB partition #2: SDA2-NTFS 100GB partition for windows #3: SDA3-EXT4 200GB por Linux #4: SDA4-2GB partition as SWAP. So I could define the SDA1-FAT32-100MB as EFI.
But after installing Ubuntu 20.04 it does not recognizes anymore Windows 7 at SDA2.
I tried to install Grub with: apt-get install grub2 // update-grub2 // grub2-install
But I still have not GRUB. I still tried to change my BIOS to LEGACY and UEFI... Bios starts as UEFI my SSD as: Kingston-480GB-Ubuntu If i take off UEFI and just put my SSD it occurs a error.
What Can I do? Grub is not default system? Ubuntu 20.04 does not recognizes Windows anymore?
