Create an EFI System Partition for a typical UEFI PC.
Choose a filesystem that firmware can read directly.
Which filesystem is normally selected?
A typical UEFI ESP uses FAT32, also known as VFAT, for firmware compatibility.
Detailed explanation
Correct. FAT32/VFAT is the widely compatible ESP format.

Incorrect. Swap is a memory-backup area and stores no normal files.
Incorrect. Swap is a memory-backup area and stores no normal files.
Incorrect. XFS is a Linux filesystem but is not the usual firmware-readable ESP format.
Incorrect. XFS is a Linux filesystem but is not the usual firmware-readable ESP format.
Incorrect. Btrfs is not the standard UEFI ESP format.
Incorrect. Btrfs is not the standard UEFI ESP format.
Try it yourself
An example you can run in a temporary verification environment.
printf '%s
' 'ESP filesystem: FAT32/VFAT'Expected result
ESPで一般に用いるFAT32/VFATKey points
- ESP commonly uses FAT32
- UEFI reads it directly
- It differs from the Linux root filesystem
Notes
- Environment: UEFI PCの一般的なESP構成
- Command output formatting can vary slightly by distribution or tool version.
- Run the example in a temporary directory or process when possible.
Foundation review
Read the scope first
Check whether the command acts on the current shell, a new process, an existing process, or a file.
Verify the observable result
Use the supplied command and compare the output with the expected result.
