I am trying to install Ubuntu on my Lenovo Ideapad 320S. It has a 4GB RAM with a 256GB SSD, boot with UEFI mode. I chose "Something else" in the disk partitioning page in the Ubuntu installer. After partitioning, there a box that requires me to choose where to install the bootloader:
From my knowledge, there are 4 possible solutions I can use to install bootloader:
Create a ext4 partition, flag as /boot, and select this partition to install bootloader
Create a ext4 partition, flag as /boot, and select /dev/sda to install bootloader
(not specifying any partition to install bootloader)
Create a FAT32 EFI partition and mark it as /efi. Now I have 2 EFI partition on my laptop.
Choose Windows Boot Manager partition as the location to install bootloader
Please tell me which possible solution I should use while installing bootloader, thank you!
