Rarely, but it can happen that the /boot partition fills up on Linux machines, in which case it’s worth deleting the old kernels, but this isn’t always straightforward.

You can check the disk usage with the following command:

df -h

The image shows the state after cleaning, so the /boot partition is now only at 39% usage

In this case, apt-get upgrade gets interrupted during the kernel update, since there’s no more space on the partition. This constantly throws errors, and there are cases (like mine) where updates can’t run at all anymore because previous ones have failed.

Because of university, I need a Linux installation as well, but due to the limited RAM in my machine, the virtual machine solution isn’t the best. (plus it’s good to have something else alongside Windows in case something goes wrong)

You can struggle a lot with the boot order/menu, which can be done very easily with a program called EasyBCD.

The main menu looks like this:

The current boot settings can be edited under Edit Boot Menu, where you can set which operating system to start by default, as well as configure the order and the timer for how long the menu is available.
