I am currently installing Ubuntu Desktop on my Windows 11 machine (dual-boot, not replacing Windows OS). I partitioned my disk in half so that half of it is for my Windows OS and the other half is free space which I can use now for Ubuntu. I am following a YouTube tutorial and am at the part where I choose my "Use as:", "mount point", and "Device for boat loader installation.
For "Use as", there are 13 options: Ext4 journaling file system, Ext3 journaling file system, Ext2 file system, btrfs journaling file system, JFS journaling file system, XFS journaling file system, FAT16 file system, FAT32 file system, swap area, Reserved BIOS boot area, EFI System Partition, physical volume for encryption, and do not use partition.
For "mount point" there are 9 options: /, /boot, /home, /tmp, /usr, /var, /srv, /opt, and /usr/local.
For Device for boot loader installation there are 7 options: /dev/sda ATA ST500LM034-2GH17, /dev/sda1 Windows Boot Manager, /dev/sda3, /dev/sda5, /dev/sda4, /dev/sdb General UDisk, and /dev/sdb4.
They can all be seen in the pictures below.
The guy in the video selected Ext4 journaling file system for "Use as" which was the default. For "mount point" there was no default but he chose /. For "Device for boot loader installation" the default was /dev/sda ATA ST500LM034-2GH17 but he chose /dev/sda1 Windows Boot Manager. Before I go ahead and install, I would like to get some second opinions to confirm that these are what I should select, and if not, which other ones I should use. The video does not talk about the different options. I am brand new to using Ubuntu and don't know what I'm doing in regards to the installation process.
This is the youtube tutorial:
