Bootcamp partition doesn't appear

Thank you for taking the time to run the Etrecheck Application.

The Report - how can I put this - is not looking good.

This machine is a Fusion Drive with a Slow Rotational Drive 5400 RPM and a small SSD 28 GB with 8 GB RAM. Right there, it is going to be slow.

The Bootcamp Partition Mounted Volumes:

disk0s3 - B******P

322.99 GB (220.99 GB used, 102.00 GB free)

MS-DOS FAT12 - This is the issue. Have never seen a MS-DOS Fat 12 Yes Fat 32 or exFat Would suggest using Bootcamp to Remove this Partition and re-create a new Bootcamp partition and start over

Mount point: /Volumes/B******P

Western Digital Software to manage the external drive. Not needed as Apple can manage the external drive without any need for third party software unless the drive is formatted as NTFS then special software is required to Read - Write to NTFS formatted drives.

Virtualbox - if you verify - it is Not Compatible with Big Sur and as of this writing - AFAIK - there is not VM Software available that is compatible with Big Sur

VMware Fusion - same as above

Start up your Mac in Windows or macOS with Boot Camp

When Bootcamp was started - was it successful in creating the Partition ? Was there any error message received when attempting to create the partition ?

Suggest downloading the Application Etrecheck directly from a Trusted Developer and well Respected ASC Contributor. The application is free or paid from added features. Run the application with Full Disc Access ( Security & Privacy - Full Disc Access ). It will take a Snap Shot -  both the hardware and software. The Report will Not Reveal Any Personal Information. Post back the Full Report - copy and paste - using the Additional Text Icon ( 3rd Icon to last )

We can have a look at the report for possible issues and may have possible suggestions to resolve the issues.

Any Third Party Applications that will interfere with the normal operation of the OS, alter, modify, remove or delete or attempt to do so is an invitation for disaster and may require a Reinstallation of the OS.

Welcome and Thank you too :-))

If Bootcamp is run and can not find the Fat12 partition to remove >> the next step is a major step to be explored only if we can not remove it.
