I'm hoping someone can help me with this. I've been through the forums, and tried the suggested solutions but I still can't get elementary to boot. (Not sure of the version but downloaded it last night.) Clearly it seems to be the same issue (though I'm sure I had a web connection.) The test boot from the USB stick worked fine. I did a clean install (no windows backup) and now am stuck at GNU GRUB v2.02~beta2-9 screen.
I tried hitting 'c' and enter as suggested in one fix post, but get 'error: can't find command 'c'.' So, moving on, I have tried all combos of configfile HD 0 through 4, and gpt 0 through 4, and even substituted msdos for gpt (as I found in a post) with no success. I'm mostly flying blind taking shots in the dark. I get what is happening and can follow directions but am otherwise a noob with GRUB, Linux etc. so I can't diagnose why the fix isn't working.
Forgive the abbreviated descriptions above as I am typing this on my phone. When typing the GRUB commands I am following the posts to the letter.
Your help is appreciated!
