I'm installing Ubuntu as a dual boot alongside Windows. I finally got a partition on my HDD (which is different than my SSD on which Windows is installed). While installing Ubuntu, I get to a message about how it will format certain partitions, which is normal, but it has "Partition #3 of SCSI2, Partition #4 of SCSI2, and Partition #5 of SCSI2" set to be formatted. Is that right? I only want it to use the 20GB partition on my F: drive, and nothing else.

Your F: drive is itself a partition on some disk. You cannot install Ubuntu on your F: drive--but you may install it on the same disk as your F: drive.

The message displayed by the installer means that:

  • It is using a disk named /dev/sdb, most likely your HDD.

  • On that disk it has created 3 partitions:

    • One EFI System Partition (/dev/sdb3)
    • One ext4 partition (/dev/sdb4) for use by Ubuntu as the root filesystem
    • One swap partition (/dev/sdb5)

This is normal for a new installation on a computer which uses UEFI and a disk which uses a GPT partition table.

It is likely that your HDD already had a Microsoft Reserved Partition and a Microsoft basic data partition (your F: drive), which in Linux would be /dev/sdb1 and /dev/sdb2.

As user @waltinator rightly says,

Anyone who attempts dual booting without reading en.wikipedia.org/wiki/Power-on_self-test, en.wikipedia.org/wiki/BIOS, en.wikipedia.org/wiki/Master_boot_record, en.wikipedia.org/wiki/GUID_Partition_Table, en.wikipedia.org/wiki/UEFI is doomed to confusion, failure and frustration.
