Thanks for those replies guys they are both excellent.
That was just the kind of info I wanted to answer part 2 of my question, I will try that later on and let you know how I get on.
The reason I haven't used the help file from a grub prompt is twofold. Firstly I didn't think of it and secondly I don't know how to get to the grub prompt anyway
Here is a list of all the shell commands I have that include the word grub:
grub-dumpbios (Manual page for grub-dumpbios (GNU GRUB 1.97~beta4))
grub-editenv (Manual page for grub-editenv (GRUB) 1.97~beta4)
grub-install (Manual page for grub-install (GNU GRUB 1.97~beta4))
grub-mkconfig (Manual page for grub-mkconfig (GNU GRUB 1.97~beta4))
grub-mkdevicemap (Manual page for grub-mkdevicemap (GRUB) 1.97~beta4)
grub-mkelfimage (Manual page for grub-mkimage (GRUB) 1.97~beta4)
grub-mkfont (Manual page for grub-mkfont (GRUB) 1.97~beta4)
grub-mkimage (Manual page for grub-mkimage (GRUB) 1.97~beta4)
grub-mkrescue (Manual page for grub-mkrescue (GNU GRUB 1.97~beta4))
grub-probe (Manual page for grub-probe (GRUB) 1.97~beta4)
grub-reboot (Manual page for grub-install (GNU GRUB ))
grub-set-default (Manual page for grub-install (GNU GRUB ))
grub-setup (Manual page for grub-setup (GRUB) 1.97~beta4)
None of these will give me a grub prompt so how do I get one? (It was so easy with grub legacy)
To both of you (and anyone else who cares to reply):
I still don't really have an answer to the first part of my question. I understand the --no-floppy bit of course. But the rest troubles me. Reading the screenshot that emorrp1 posted it suggests that the boot loader is being told to 'search' for a particular file system uid and when it finds it to give that file system the variable 'root'. That is fair enough I guess, but the bit that puzzles me is that in the line before the 'search' line one I have:
- Code: Select all
Is this not telling it to do exactly the same thing in another (and far simpler) way?
If that is so, then I guess that explains why quite a few people on various forums have removed the 'search' line and still got a satisfactory (or improved) boot.
