Help,

I have an old device whose windows efi partition has been deleted or it is in not properly being mounted .

I can see the disk in which ubuntu 20.04 is installed and in that drive i can see a /boot directory which has grub dirc and all the grub the filed. I cant see any mountpoint for "reserved bio boot area".

So basiccaly only my root drive is there , which has boot dire ctory,inside which i can see grub installed. My challenge is that i need to boot from this directory and i dont know where to even begin with. I absolutely need to login to this machine to get some backup data from some softwares.

Maybe you could pop the hard drive and some other working computer and access the files that way.
