How's the GRUB knowledge in these 'ere parts . . . . . .

Here’s another for you good people hopefully :slight_smile: Hope you don’t mind a re-post as I tried this on the mint forums but no luck :frowning:

I have a USB that I use as a multi boot stick - I’ve just added two versions of mint 64 bit to it and tried to edit the grub config file to add them, seems I’ve not quite got it right . . . . . it now just goes to a grub > prompt with some text when I try to boot off it - I assume this is an error in the last two enties but I don’t know what bit I may have got wrong -
can someone take a peek and point me in the right direction please…

I guess the first thing to do would be to comment out (or remove) the last two entries and see if it works again ?

It does, that’s exactly my point, I don’t know what’s wrong with them, and to be honest I don’t know where to start looking for them - I know something needs altering/editing, I just don’t know enough about the syntax (is that it?) to do it myself…

Is what you’re saying that the GRUB menu displays correctly, but if you choose one of the bottom 2 you just get returned to the grub prompt ?

or are you saying with those 2 entries present, the GRUB menu never gets displayed ?

I’ve had a strange day . . . . I was in the garden when a fly went straight into my eye, bugger to get out, I defrosted a small fridge/freezer and ruined it, on the way to get a new one I opened the sunroof and another fly went in my eye - I came home, got done, back to normal, put the USB in the laptop to get the exact error message -

And it works perfectly . . . . . . . . . ??? I have been afflicted by SODS LAW !

I’m going out to have a beer and watch a film, I will not open the sunroof . . . . . . .lol . . . . . . .

At least you get to laugh at those kinda days later…

Glad it’s all working :))
