1.05.2Basic
Create an EFI System Partition for a typical UEFI PC.
Choose a filesystem that firmware can read directly.
Which filesystem is normally selected?
× Incorrect
A typical UEFI ESP uses FAT32, also known as VFAT, for firmware compatibility.
Detailed explanation
CorrectFAT32（VFAT）
Correct. FAT32/VFAT is the widely compatible ESP format.
Incorrectswap
Incorrect. Swap is a memory-backup area and stores no normal files.
IncorrectXFS
Incorrect. XFS is a Linux filesystem but is not the usual firmware-readable ESP format.
IncorrectBtrfs
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
- Use read-only inspection or a disposable disk when learning storage commands.
- Partition and LVM writes can destroy data; verify the target before running them.
Foundation review
Place the operation
Firmware compatibility for the ESP is distinct from the filesystem used by Linux root or data volumes.
Check the side effect
Verify firmware and distribution requirements before formatting an ESP.
