Before you do anything, backup /home. You can reinstall your system while preserving your /home partition, and reinstalling is probably the cleanest and safest way to do this. It allows you to move the boot and filesystem partitions to the start of the disk, and then resize /home to fill the rest of the drive. You could manually move the partition but it’s slow and riskier when messing with a boot and main filesystem partition; much easier to start again tbh. I’d get a USB and install Ventoy on it. Ventoy is a great bootable USB tool that lets you put multiple bootable ISOs on it & pick one at boot; great for installs and also to keep around as a recovery drive. I’d then put on it a ISO file of your preferred linux distro, and also an ISO file of a good live distro for recovery. GParted Live is particularly good USB live distro for this because resizing the partition is the aim. I’d then boot up the USB drive and select the ISO for your Linux distro’s installer. In that, I’d then use the partition tool in your installer, delete all the windows partitions (sda1, sda2, sda3 and sda4), and then delete the exisiting boot (/boot/efi) and root file system (/) and create new ones at the beginning of the disk: 1gb /boot/efi and 85gb system partiton as you have now, and ensure the /home partition is kept and mounted as /home in the new install. You’ll have loads of free unpartitioned space; leave that for now. After the system is reinstalled, I’d boot in, check everything is ok, and then restart and boot the USB again, this time selecting GParted Live. Then with GParted Live, I’d resize the /home partition to fill all the empty space. But as I said, before you do anything, backup /home.
