Question #: 76
Topic #: 1

A Linux server was recently updated. Now, the server stops during the boot process with a blank screen and ans> prompt. When of the following is the MOST likely cause of this issue?

AThe system is booting to a USB flash drive

BThe UEFI boot was interrupted by a missing Linux boot file

CThe BIOS could not find a bootable hard disk

DThe BIOS firmware needs to be upgraded

Show Suggested Answer

Suggested Answer: B

The most likely cause of this issue is that the UEFI boot was interrupted by a missing Linux boot file, such as grub.cfg or vmlinuz, which are essential for loading the Linux kernel and booting the system. The s> prompt indicates that the system entered into UEFI Shell mode, which is a command-line interface for troubleshooting UEFI boot issues. The administrator can use UEFI Shell commands to locate and restore the missing boot file or change the boot order. Verified Reference: [UEFI Shell Guide]

Upgrading the BIOS firmware? Sounds like a lot of work. I'd rather just unplug the server and hope it starts up again. Option C is my pick.

Good idea. Let's make sure everything is properly connected before trying anything else.

I agree, that could be the issue. Maybe we should check the connections to the hard disk.

I think option C is the most likely cause. The BIOS might not be able to find a bootable hard disk.

Haha, booting to a USB flash drive? That's a classic! But I don't think that's the case here. I'd go with option C as well.

Hmm, I'm not sure about that. It could also be a missing Linux boot file, so option B seems more plausible to me.

The blank screen and ans> prompt definitely points to a BIOS issue. I think the BIOS couldn't find a bootable hard disk, so option C is the most likely cause.
