Ubuntu laptop boots in EFI Shell instead of OS

sd flag

starting up my laptop this morning running Ubuntu goes directly into EFI shell. Not sure what this failure might be. I have reset a few times and gone into the Boot Manager to see anything unusual in the settings, looks ok.

Is there commands I can run to force my OS to start or could this be another error I need to look for!

also there seem to be no map in EFI shell so I cannot see my drives – enter image description here

Have you check and confirmed "Ubuntu" is selected in the Boot menu?

Please copy & paste the pastebin link to the Bootinfo summary report ( do not post report), do not run the auto fix till reviewed.Lets see details, use ppa version with your USB installer (2nd option) or any working install, not Boot-Repair ISO https://help.ubuntu.com/community/Boot-Repair https://sourceforge.net/p/boot-repair/home/Home/

I'm in Boot Manager after exit in EFI Shell and can only see Boot Override which is Ubuntu. I have also used hard disk instead of USB-LAN in Boot sequence order and have rebooted, still same issue just boots into EFI Shell EFI Shell version 2.50 current mode 1.1.2 map:cannot find the required map name

Downloaded Boot-repair, using Rufus made the USB ISO bootable. Ran and there are no boot issues found by Boot-Repair. Installed Boot Update from here, shutdown removed USB goes back to EFI Shell no luck, no sector errors on the hard disk either.

enter image description hereI opened the laptop and tightened all connectors to the motherboard. Powered on and even though I am booted into the EFI shell, I can now see fs0 and launch grubx64.efi into the OS ubuntu.......Looks to be that there was a connector loose on the motherboard, even so now the disk is seen and I can map, why I am still booting into EFI?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
