LPIC-1 System Architecture Practice Question
Which TWO of the following are required for a system to boot using UEFI?
⚠ Common exam trap
A common mix-up: candidates confuse UEFI requirements with legacy BIOS requirements, mistakenly thinking the MBR or a BIOS boot partition is needed, or assuming EFI stub support is mandatory when it is only an optional feature for direct kernel booting.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The bootloader installed in the ESP
In UEFI boot, the bootloader must reside in the EFI System Partition (ESP) as a file (e.g., /EFI/BOOT/BOOTX64.EFI) that the UEFI firmware can directly load. Option B is correct because the ESP must be formatted with FAT32 (or FAT16 for older systems) as per the UEFI specification, which requires a specific partition type (GUID C12A7328-F81F-11D2-BA4B-00A0C93EC93F for GPT) to store bootloaders and drivers.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The bootloader installed in the ESP
Why this is correct
The bootloader (e.g., GRUB) must be installed in the ESP for UEFI to find it.
- ✓
An EFI System Partition (ESP) formatted with FAT32
Why this is correct
The ESP is required for UEFI boot to store bootloaders and drivers.
- ✗
The bootloader installed in the Master Boot Record (MBR)
Why it's wrong here
MBR boot is for BIOS, not UEFI.
- ✗
A BIOS boot partition
Why it's wrong here
BIOS boot partition is used for GRUB on BIOS systems with GPT.
- ✗
A kernel with EFI stub support
Why it's wrong here
The kernel can be booted directly with EFI stub, but a bootloader is not required; however, the question asks for required items, and EFI stub is not strictly required.
