Can't find root device [SOLVED]

Hi,

Apologies if this too dumb to be true or if it's been answered before. But I'm having to manage a house move with elderly parents and associated legal issues at the same time so overly stressed. Would be immensely grateful for help. I have some experience with arch and find that I can usually fix problems without asking the forums but I'm basically a beginner. I'm writing on my mobile phone so apologies for the formatting.

I mistyped my password three times on gnome 40, then did the stupid thing (stupid,stupid,stupid, I know) and used the button to force shutdown.
Then I got a message from secure boot which I promptly disabled (hadn't appreciated it was on to begin with).

Then when I boot, I get the usual boot screen (systemd-boot) and it seems to start but:

:: running early hook [udev]
Starting version 249-3-arch
:: running hook [udev]
:: Triggering uevents
Waiting ten seconds for device /dev/disk/by-uuid/f3a....(the whole number)
ERROR device 'UUID=f3a...' not found. Skipping fsck.
mount: /new_root: can't find UUID=f3a...
You are being dropped to an emergency she'll.
sh: can't access try; job control turned off

Additionally, when I boot using the install medium, I can't find the disks to chroot into. fdisk -l finds only the installation medium proper.

Anyway, I'm desperate, help would be very much a life saver

Either the drive died and that caused the initial crash or the UEFI blocks access to it because of the unspecified secure boot incident.
=> The answer is in the BIOS/UEFI

Thank you! It was indeed had to reset a setting in the BIOS/UEFI. I'll sort put the details on later and mark it solved. Thank you, thank you, thank you.

Re: Can't find root device [SOLVED]

So problem was the SATA mode had changed from the correct one which is AHCI. I think I'm going to keep secure boot off.

Anyway, thanks again, during a very stressful time
