Which option would be APFS? As in which one do I choose? They were like 4-5 different options.OK, format Crucial to APFS and see what OS it installs (Catalina I guess).

Again thanks for your patience. I have located a Mojave installer file and it’s downloading on my pc. When it’s done do I just transfer the .dmg file over to my usb flash and that’s it?OK, you'll have to make an USB installer of Mojave (on PC or Mac).
Okay I have downloaded a dmg editor and I’m just waiting for the .dmg Mojave file to download. It looks like it’s going to be a while. I will update ASAP. I’m def going to need instructions on what to do.You're very welcome!
I understand it's not so easy, sorry about that ; )
I would not just transfer the dmg to USB, but use an app for it.
AFAIK Transmac works .
I'm afraid you'll have to google a bit and search for tutorials about how to make a bootable installer for Mac on PC.
The MBP 2012 is a very nice machine, the effort is worth it, dont give up!
The dmg file should be about 6 GB .Okay I have downloaded a dmg editor and I’m just waiting for the .dmg Mojave file to download. It looks like it’s going to be a while. I will update ASAP. I’m def going to need instructions on what to do.
Yeah it says 5.6 GB but my internet service is terrible every morning between 8-9am. I’m not sure why but it never fails. That’s why it’s taking so long.The dmg file should be about 6 GB .
Yet another issue. My usb flash drive is only 3.8 GB so I can’t fit the .dmg file on it.The dmg file should be about 6 GB .
okay I’ve got the .dmg file onto the usb using transmac. Now what?The dmg file should be about 6 GB .
I'd plug it in the MBP ,startup and keep the option key pressed , choose the USB and see what happens : )okay I’ve got the .dmg file onto the usb using transmac. Now what?
But there’s still no APFS option…I'd plug it in the MBP ,startup and keep the option key pressed , choose the USB and see what happens : )
Once booted, you may have to format the internal drive to APFS in Disk Utility before running the installer.
Are you sure you booted from the USB and not in recovery mode?But there’s still no APFS option…
I was in recovery mode. I tried booting from usb but this happened … I held option. For the sake of the video I didn’t choose my wifi but I did that originally and then clicked the Mac OS X from usb and same thing happened.Are you sure you booted from the USB and not in recovery mode?
I watched a video on YouTube on how to make the bootable usb using transmac so I know I did it right.Are you sure you booted from the USB and not in recovery mode?
The USB installer is not recognized , sometimes the USB stick itself is the culprit.I was in recovery mode. I tried booting from usb but this happened … I held option.

It’s all good I think I’m throwing in the towel. This should have worked. Thanks for your help.The USB installer is not recognized , sometimes the USB stick itself is the culprit.
I'd try another USB stick or external drive and make a new installer.
Sorry to hear that!It’s all good I think I’m throwing in the towel. This should have worked. Thanks for your help.
Yes I am very new to MacBooks and I def blame myself for not having a backup.OP:
Your posts in this thread are "all over the place" -- flopping around like a fish out of water.
I also sense that perhaps you are learning why one should never never NEVER erase a Mac's internal drive unless one has an EXTERNAL backup of some sort -- preferably a bootable cloned backup created with either CarbonCopyCloner or SuperDuper. One ALWAYS must retain a way to "boot to the finder" in an emergency.
Referring to your post 29 above:
IF you are going to install
Mountain Lion (10.10)
El Capitan (10.11)
Low Sierra (10.12)
or High Sierra (10.13)
Then you want "Mac OS extended with journaling enabled, GUID partition format".
IF you are going to install
Mojave or later (Catalina, Big Sur, Monterey)
Then you want "APFS, GUID partition format".
When using disk utility YOU MUST BE CAREFUL to check the upper left for the option to "Show ALL devices".
You CANNOT ERASE THE ENTIRE INTERNAL DRIVE UNLESS you have gone to the View Menu and chosen "show ALL devices".
BE AWARE that older versions of disk utility don't have this option.
But if the option "is there to choose", then you MUST choose it.
Next, you "look over to the left" and choose the TOPMOST line that represents the PHYSICAL DRIVE inside the Mac.
Note:
If disk utility doesn't offer you the option to format to APFS, that's because you're using a version of disk utility that is TOO OLD, because you're trying to install an older version of the OS and disk utility will only format to the disk formats that it "understands".
Let's get something straight:
Have you tried just booting to internet recovery
Command-OPTION-R
... and then accepting whatever version of the OS it offers to you?
You will need to erase the internal drive first.
See the first part of my reply above.
