Unfortunately no. The Ubuntu 24.04 installer will *_not _*take care of
creating
the mount point on the second drive for /home.
You will have to manually go to the terminal and create/set up the
disks from the install ISO.
I recently went through this with Mint.
Here's the notes I used attached. Reminder to select format after you
select the disks and partition mount points
Make sure you create a EFI partition

format the second drive and make the mount point myself?
Thanks!

Ctrl+Alt+Fn +any function key does not give me a CLI on the old system.
Since I am installing Ubuntu on one drive and /home/mark on another drive,
I don't think I need LVM, either.

This is good advice.
take advantage of its features
Among these, I'd specifically include
* altering the size of your filesystems
* integrating new disks into your filesystems
* snapshot-based backups
If you have local disk capacity far beyond what you currently need,
LVM would provide a handy way to right-size your current filesystems
while giving yourself a lot of flexibility for future expansion.

Step-by-Step Guide with EFI System Partition:
1. Boot from Installation Media:
• Insert your Linux Mint installation media and boot from it.
• Select "Start Linux Mint" to begin the installation process.
2. Prepare the Disks:
• Open a terminal and use fdisk or parted to prepare your disks. For this
example, we'll use fdisk.
bash
sudo fdisk /dev/sda
• Delete any existing partitions on /dev/sda by typing d and following the
prompts.
• Create a new partition for the EFI System Partition:
? Type n to create a new partition.
? Choose p for a primary partition.
? Accept the default partition number.
? Accept the default first sector.
? Set the last sector to create a 512MB partition (or 1GB if you prefer
more space).
? Type t to change the partition type to 1 for EFI System.
? Write the changes and exit by typing w.
• Create a new partition for the root filesystem:
? Type n to create a new partition.
? Choose p for a primary partition.
? Accept the default partition number.
? Accept the default first sector.
? Set the last sector to use most of the disk, leaving some space for
the swap partition (e.g., 20GB for root, 4GB for swap).
? Type t to change the partition type to 8e for Linux LVM.
? Write the changes and exit by typing w.
• Repeat the process for /dev/sdb, but this time, create a single partition
for the home directory:
? Type n to create a new partition.
? Choose p for a primary partition.
? Accept the default partition number.
? Accept the default first sector.
? Accept the default last sector to use the entire disk.
? Type t to change the partition type to 8e for Linux LVM.
? Write the changes and exit by typing w.
3. Create Physical Volumes:
• Create physical volumes on both disks:
bash
sudo pvcreate /dev/sda2
sudo pvcreate /dev/sdb1
4. Create a Volume Group:
• Create a volume group that spans both disks:
bash
sudo vgcreate vg_mint /dev/sda2 /dev/sdb1
5. Create Logical Volumes:
• Create logical volumes for the root, swap, and home directories:
bash
sudo lvcreate -L 20G -n lv_root vg_mint
sudo lvcreate -L 4G -n lv_swap vg_mint
sudo lvcreate -l 100%FREE -n lv_home vg_mint
6. Format the Logical Volumes:
• Format the logical volumes with the appropriate filesystem types:
bash
sudo mkfs.ext4 /dev/vg_mint/lv_root
sudo mkswap /dev/vg_mint/lv_swap
sudo mkfs.ext4 /dev/vg_mint/lv_home
7. Format the EFI System Partition:
• Format the EFI System Partition with a FAT32 filesystem:
bash
sudo mkfs.fat -F 32 /dev/sda1
8. Mount the Filesystems:
• Mount the root and home logical volumes:
bash
sudo mount /dev/vg_mint/lv_root /mnt
sudo mkdir /mnt/home
sudo mount /dev/vg_mint/lv_home /mnt/home
sudo mkdir /mnt/boot/efi
sudo mount /dev/sda1 /mnt/boot/efi
9. Proceed with Installation:
• Start the Linux Mint installer and choose "Something else" when prompted
for the installation type.
• Select the mounted root partition (/dev/vg_mint/lv_root) and set it as
the root filesystem (/).
• Select the swap partition (/dev/vg_mint/lv_swap) and set it as swap
space.
• Select the home partition (/dev/vg_mint/lv_home) and set it as the home
directory (/home).
• Select the EFI System Partition (/dev/sda1) and set it as the EFI System
Partition.
• Proceed with the installation, following the on-screen instructions.
10. Post-Installation:
• After the installation is complete, reboot the system.
• Update the GRUB configuration to ensure it recognizes the new LVM and EFI
setup:
bash
sudo update-grub
Summary:
• Disk 1 (/dev/sda): Contains the EFI System Partition (/dev/sda1), root,
and swap logical volumes.
• Disk 2 (/dev/sdb): Contains the home logical volume.
• Volume Group: vg_mint spans both disks.
• Logical Volumes: lv_root (20GB), lv_swap (4GB), lv_home (remaining
space).
This setup ensures that your system is compatible with UEFI boot and provides a
flexible and scalable storage solution for your Linux Mint installation,
utilizing LVM to manage disk space across two disks.
Creating volume groups during a Linux installation typically involves using the
Logical Volume Manager (LVM). LVM allows for flexible disk management by
organizing physical disks into volume groups, which can then be divided into
logical volumes. Here are the detailed steps to create two volume groups when
installing Linux:
1. Prepare the Installation Environment
• Boot from Installation Media: Start by booting your system from the Linux
installation media (USB, DVD, etc.).
• Select Installation Type: Choose the installation type that allows for
manual partitioning, such as "Custom" or "Advanced" installation options.
2. Open the Partitioning Tool
• Access Partitioning Tool: During the installation process, you will be
prompted to set up your disk partitions. Choose the option to manually
configure partitions.
3. Create Physical Volumes
• Identify Disks: Identify the disks you want to use for your volume
groups. You can use tools like fdisk or parted to create partitions on these
disks.
• Create Partitions: Create partitions on the disks you want to include in
your volume groups. Ensure these partitions are of the type "physical volume
for LVM" (type code 8e in fdisk).
4. Initialize Physical Volumes
• Initialize with pvcreate: Use the pvcreate command to initialize the
partitions as physical volumes. For example:
bash
• pvcreate /dev/sda1
pvcreate /dev/sdb1
5. Create Volume Groups
• Create First Volume Group: Use the vgcreate command to create the first
volume group. For example:
bash
• vgcreate vg01 /dev/sda1
• Create Second Volume Group: Create the second volume group using a
different set of physical volumes. For example:
bash
• vgcreate vg02 /dev/sdb1
6. Create Logical Volumes (Optional)
• Create Logical Volumes: You can create logical volumes within your volume
groups. For example, to create a logical volume named lv_root in vg01:
bash
• lvcreate -L 20G -n lv_root vg01
• Format Logical Volumes: Format the logical volumes with a filesystem. For
example:
bash
• mkfs.ext4 /dev/vg01/lv_root
7. Mount and Configure Filesystems
• Mount Logical Volumes: Mount the logical volumes to the appropriate
directories. For example:
bash
• mount /dev/vg01/lv_root /mnt
• Update /etc/fstab: Ensure the logical volumes are mounted at boot by
updating the /etc/fstab file with the appropriate entries.
8. Complete the Installation
• Proceed with Installation: Continue with the rest of the Linux
installation process, ensuring that the installer uses the configured LVM
setup.
Example Commands Summary
bash
# Initialize physical volumes
pvcreate /dev/sda1
pvcreate /dev/sdb1
# Create volume groups
vgcreate vg01 /dev/sda1
vgcreate vg02 /dev/sdb1
# Create logical volumes (optional)
lvcreate -L 20G -n lv_root vg01
mkfs.ext4 /dev/vg01/lv_root
# Mount and configure
mount /dev/vg01/lv_root /mnt
# Update /etc/fstab as needed
