Different drive name between disk utility and boot utility

It seems correct:

The Samsung SSD seems to be the disk with the OS on it, and the OS-start partition is called Macintosh.

The second picture (2) shows you names that you can start of = are connected (when you start up while holding the Alt-Option key), but not the same as in the first picture:

disconnect /eject all external disks and make the same picture 1 and 2.

The main part in Disk Utility starting with "Samsung SSD 85.." is the model number of your SSD. The part below is the Drivename or Partition name "Macintosh". Macintosh is the default partition name for your boot disk. My guess is that it was cloned and retained the original name.

You are showing a second hard drive model number "APPLE HDD HTS ..". This looks like it has 2 partitions, "Time Machine" and "Docs".

Using disk utility, you can select the partition "Macintosh" with your mouse and then select "File" from the top menu bar and then select "Rename". This will allow you to rename Macintosh to whatever you want.

In my case my original HDD was called "Macintosh". When I installed an SSD I gave it the name Samsung SSD.

I put the original hard drive in the optical bay and renamed it to "Macintosh HD". I though those name would make it easier for me to identify them.

So if Macintosh bothers you, select something that makes sense.

The names of disk 2 (in the DVD reader's place) are probably the "old names" when that disk was in the 'startup' location.

You can easily change the names of the second disk:

in Finder set the Preferences-Sidebar to display all the 'devices'. then choose your macbook in the sidebar and in the right panel rename "Macintosh HD" to 'TM-Backup' (assuming that this is the disk with the TM backup) and rename the one called "Docs" to 'Docs-1'.

Then rename the startup partition on the SSD to 'Macintosh-SSD'.

Then in SystemPreferences->StartupDisk set the Macintosh-SSD as the startup disk, and restart.

-- of course you can make the names what you want --

After the restart open TimeMachine Preferences and "re-connect" TM to the new name.

After this the boot list (start with At-option key) should display the 'correct' names.

Notes:

- the size of a TimeMachine disk should be about 3 times the size of the OS disk (old "rule")

- next time rename when you partition/erase a disk

- it is wise to have a dedcated TM disk with nothing else on it: a dead disk is dead in all partitions.

John:

I am assuming that when you start your computer it boots into the correct drive without you having to select anything.

i.e. if you go under "System Preferences" and then "Startup Disk" you will see the correct drive is selected.

You have to be very careful when playing with partitions. You could lose all the information on your hard disk.

Here is a thread to read as an example:I erased drives and now on startup there is a circleslash

I would recommend leaving it as is, but if you insist on trying to get rid of it, the first thing to do is backup all data.

When I installed my SSD what I did was:

1. I cloned my existing drive.

2. Replaced the Old hard drive with SSD.

3. Put the old hard drive in a caddy and installed in place of the Optical Drive.

4. Once I was certain that the SSD was working correctly, I erased the old hard drive and made it non-bootable.

5. Copied all the information I did not want on the boot drive, such as movies, music, etc. to the Old Hard Drive.

But if you start playing with re-formating or deleting partitions, be prepared to lose all information on drive.
