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?

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]

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.
