I formatted a 1 TB drive to ext4 to install 20.04 LTS, I'm tired of using live sessions from usb that are doomed to crash eventually and also not let me use all the power of my desktop. The bar on the drive with Linux Mint 17.3 is green, because grub is installed there I guess, but it's not formatted as EFI, none of my drives/partitions are, this motherboard is able to deal with BIOS style installs but also EFI. It seems like it's a very bad idea according to the installer to go ahead, but I can just press delete after the boot screen where memory, drives external and internal are listed and get into the fancy gui that is UEFI I guess and change the boot drive order.
It shows the 1TB drive I formatted to ext4 in orange, tells me I should create an EFI partition even if I decide to go ahead, of 35MB at least, and I got really annoyed by then. This desktop had Mint 17.3 and Win7 (until it became useless last year after January, everything windows on that ntfs drive was removed). I wonder what would happen if I format the drive with Mint 17.3, so I would have no hard drives with grub installed on it and the drive that had win7 still has an MBR, but I know how to get rid of that.
Is all of this EFI stuff necessary? The last Linux I used installed permanently on a drive was Mint 17.3 and it seems like things have changed software-wise but there's nothing that changed with this desktop except for a usb 3.0/eSATA-III dock for mechanical HDD's that are normally internal that is plugged to an usb 3.0 hub, hot swap and all. It's not relevant to the problem here so...am I being scared away from installing? I'm really tired of running live sessions!
Have a good day everyone.
