I just installed Ubuntu 12.04 as a dual boot with my Windows 7. I was using the Grub Customizer to mess with the Grub menu. I changed the resolution of the grub menu using Grub Customizer from 1900x1080x8 (or 16) to 1900x1080x24. Upon reboot I can no longer see my Grub menu. I can hit up/down arrow and select the OS by guessing.
After one of my hard drives failed on laptop i had to re-install Windows7 along side my Ubuntu 13.10 OS on the same Disk, of course doing this removed the Grub menu on start-up so i have no option to choose which OS to use and it boots straight into Windows :(
Am i correct in saying if i put a Ubuntu install media (USB) in and do a repair it'll put (create) the Grub Menu back, thus allow
My grub menu went through rather extensive changes after the last update. It started booting to my old 12.04 entry by default. Where this gets confusing is that there is no longer a 12.10 entry in grub.cfg.
I installed and tried the grub-cfg as mentioned in How do I change the grub boot order?
I am running 12.04 and after doing some updates I ran grub customizer to clean up the grub menu. I swear I only unchecked Linux entries with old kernels, but when I restarted the only grub choice is for the windows 7 partion.
I have created an entry in /etc/grub.d/40_custom. I then ran grub-mkconfig -o /boot/grub/grub.cfg. The entries are there, but when I boot, they don't show up in the menu. Am I missing a step for adding a menuentry to grub?
Can I make changes to /etc/boot/grub/menu.lst from the GRUB Menu that says 'Hi' to me when my machine boots up?
e.g. Linux is installed in (hd0,0) and windows in (hd0,5). The windows' one is set to default in /etc/boot/grub/menu.lst. Now when my machine boots up, I want my windows to boot up BUT I also want that the next time when I restart, Linux must boot up by default.
Looks like you are not using Chakra's grub to boot.If you do know that for example, it is Ubuntu's grub and it is still installed there, go to Ubuntu and at terminal, "sudo update-grub" If you don't know, what OS is at the top of the menu?print out that grub's grub.cfg (or menu.lst)as well as fdisk -l and blkid
