Question Can't boot to debian. Stuck in EFI shell

[khodex1997]

I had this server working and booting to debian (or atleast I remember it as debian) but ever since I moved I can't get it to boot. The farthest I get is the efi shell.
I have tried changing the sata mode.
Fast boot is off.
I tried changing the port on the motherboard.
Reseating the cmos did nothing.
The bios was already up to date but I tried that anyways.
I even took the drive out and put it in my main pc and I was able to boot to it on there. (but it had some network issue or something. I assume cause it was a different motherboard.)

Most recently I tried download boot-repair-disk by yannubuntu and it booted in legacy mode but told me to boot in uefi which then just takes me to the efi shell. Even if I go into the boot menu and select the flash drive it takes me to the shell.

I'm at a loss on what to do. Everything seems to function fine elsewise. (other than the pc not booting if the 10-fan fanhub is plugged into the psu but I'm assuming it just draws too much power)

Any suggestions? My motherboard is a msi z97 gaming 5 (repurposed from my old build)

The efi shell just shows a drive map but I can't get it to list the directories

then your drives arent working, recheck that they are properly mounted

efi shell is similar to unix command line, you can mount drives, launch apps (including debian)

I tried mounting fs0 but it still wouldnt display the directories

check cables

check cables

I have checked the cables they are connected firmly. I tried moving sata ports too. I even just tried a different sata cable.
I do "mount fs0"
and it says success so then I type "fs0:" to move to that drive but when I do ls or dir it just says "Cannot open current directory - Not Found".
It does that for all the partitions.

I mounted all of the partitions and I was able to do do "cd efi\debian" and launch shimx64.efi then I did startx so now I am in. I just need to figure out how to install boot-repair

You must have a UEFI-bootable boot repair disk. This can be done by using Rufus to write it and choosing the GPT partition scheme for UEFI boot.
