Boot errors after installation

[Cai]

I've been running Mint with no problems for about 4 months (first Daryna, then upgraded to Elyssa).

HP Desktop, 250 GB memory, 1 GB RAM, don't know the rest of the specs from memory

My power supply cord got knocked out of the wall, forcing a hard reboot. When it came back, I was able to boot to the first LinuxMint screen (with the green loading bar), but no further.

I get "Grub Error 13", which says something about my executable files being in the wrong format.

Is there anything I can do to fix this, or do I need to completely re-install Mint? (I'm hoping there's a fix, as I'm an idiot who lost my boot disk, and so without good internet access I'll probably have to have a disk shipped to me to re-install).

Hi

Could you please post your menu.lst file and also the answer from the following by opening a terminal and entering:

sudo fdisk -l

I can't even get as far as the ability to open a terminal. I can get a command line, but it's a GRUB command line, not the usual terminal one.

Since you have no live CD the only thing I could suggest is booting into recovery mode as described here:

https://wiki.ubuntu.com/RecoveryMode

It may do nothing but drop you to a command line but it may also tell you somewhat what needs to be done.

Sorry I was assuming that you had a live cd and could access your files by booting the CD.

If you have not got one then it would probably help if you could download and burn another CD.
