So in my attempts to move all my OSes to a single drive for streamlined backup, I finally decided to replace of my old, cluttered Win10 installation on a drive I want to reserve for data with a fresh install via bootable USB to an empty 500GB HDD. It’s gonna be a triple-boot machine with Windows getting the bulk of the drive.
I had previously used the 500GB for testing out Manjaro KDE, but had purged the disk by creating a new partition table; or so I thought. After I had installed Win10, I noticed that the sole accessory partition it created (it only created one for some reason; “Microsoft reserved partition” to be precise. I did install it before deleting the old Windows partitions. So maybe that’s the reason) was using an ext4 filesystem and had one of the labels I had used previously for the Manjaro KDE test run.
Now after having removed the old Windows partitions, I cannot boot into the new one. I figure a new install is all that is needed, but why is it using ext4 filesystems and is it going to cause me problems. (Note: the basic data partition is NTFS)?
