grub problem

[themis]

If you have a working system but have to manually boot you should reinstall grub from your boot.

sudo grub-install /dev/sda
If that returns any errors run:
sudo grub-install --recheck /dev/sda
Then:
sudo update-grub

it did work!
I have my grub back!

Time to solve the initial problem!...hold on!
I am working now with two keyboards.
I realized that the USB keyboard doesnt work on grub menu,
whereas the 'analog' one does.

USB legacy function on BIOS is enabled.
Thank you oldfred!

With a working Grub 2, try adding this line to /etc/default/grub:

GRUB_PRELOAD_MODULES="usb_keyboard"

Save the file, then "sudo update-grub" to get this into the grub.cfg file.

I haven't used this since I've not had problems. The intent is to preload the usb keyboard module as Grub 2 loads. Perhaps it will work for you.

what do you mean 'with a working grub 2'??
should I exec grub first?

I just meant that now that you have everything working, you can just add this to /etc/default/grub by editing the file in the normal manner (gksu and your text editor of choice). No having to change anything during boot, run extra commands, etc. Sorry if it was confusing.

I did it,
and now i boot and it stops at GRUB loading..
and reboots, and if I let it, it will continue rebooting forever!

Ok. Can you get back to the desktop and remove the line and update grub again?

If not, if you can get to the command line at the menu, press "c" and then remove the usb_keyboard module by typing "rmmod usb_keyboard". Press ESC, then highlight the kernel you want, press "E" and cursor to the "insmod usb_keyboard" line (if it exists) and use the DEL key to remove the line. Then ctrl-x to boot.

how can I get to the command line at the menu>>>???
Which menu do you mean?
It doesnt reaches the point where it shows the available OSs.
It reboots before that.
BIOS does work, but I believe this has nothing to do with what you are telling me to do.
fffff... that was close!

No it doesn't have anything to do with the BIOS.

Is it fixed? I didn't think so.

If you can hold down SHIFT you might get a chance to see the menu - but I doubt it's getting that far. But if you can, then the instructions in the previous post would apply.

If you can't, boot the LiveCD to the Desktop, mount the Ubuntu partition, and then open the grub and grub.cfg files for editing. Substitute your text editor for "gedit".

sudo mount /dev/sda9 /mnt
sudo chmod +w /mnt/boot/grub/grub.cfg
gksu gedit /mnt/etc/default/grub /mnt/boot/grub/grub.cfg

Remove the GRUB_PRELOAD_MODULES="usb_keyboard" line from grub.
Remove the "insmod usb_keyboard" line from grub.cfg
Save both files.

Reboot and your system will be back to the way it was - working but still having your keyboard issue.

Ok, I have my system back.
One last thing before we give up the try.
I had xp. then installed win 7.
I had these problems at the win loader too, before installing
ubuntu. Does this help?

Thank you anyhow for your patience.
I'll get an analog keyboard first thing in the morning!

Do you have another usb keyboard to find out if this is a hardware issue specific to this keyboard? You should not have problems with usb keyboards, and the fact that you had the same problem with windows makes the hardware issue even more likely.
