Update: I found a solution!

I am having the same problem as this person, but the solution is not working for me.

I am booted into a grub prompt with minimal bash editing. My partitions are:

  • boot loader in /dev/sda
  • /boot in sda7 (Primary Ext2)
  • Swap in sda8 (Logical)
  • / in sda9 (Logical Ext4)
  • /home in sda10 (Logical Ext4)
  • The rest are windows partitions (dual boot)

So I tried the following:

configfile (hd0, gpt9)/boot/grub/grub.cfg

Which only gets me: 

error: filename expected

I tried all the other partitions (1 through 10) just to be sure, but they all get the same error.

Miscellaneous

When I enter 

configfile (hd

I get 

hd0 hd1error: failure reading sector 0xfc from 'hd1'.
error: failure reading sector 0xe0 from 'hd1'.
error: failure reading sector 0x0 from 'hd1'.

When I enter: 

configfile (hd0,gpt

I get {I leave out the partition sizes after gpt2, but they are there. I can retrieve them if necessary}:

Possible partitions are:
Partition hd0,gpt1:  Filesystem type fat - Label 'SYSTEM', UUID 14E4-FCC4 - Partition start at 1024KiB - Total size 102400KiB
Partition hd0,gpt2:  No known filesystem detected - Partition start at 103424KiB - Total size 921600KiB
Partition hd0,gpt3:  No known filesystem detected 
Partition hd0,gpt4:  No known filesystem detected 
Partition hd0,gpt5:  No known filesystem detected 
Partition hd0,gpt6:  No known filesystem detected

  • Hey can you try that with an extra space in it? configfile (hd0, gpt9) /boot/grub/grub.cfg

  • Also, take a look at askubuntu.com/questions/509423/… and let me know.

  • @LewisGoddard It doesn't work with an extra space, and I answered my own question after a few hours of struggling with it. Thanks, though.

I found a solution hidden in the comments. Run this on your grub screen:

configfile /efi/grub/

and hit tab (you may need to wait half a minute for it to load) It should give you a list of possible files. I chose cfg

configfile /efi/grub/grub.cfg
