I was using ubuntu 11.10 with gnome-shell. I installed various useful softwares and ran system update using update manager which ran smoothly and asked me to restart my comp at the end. I restarted it to find that Ubuntu entries were missing from the GRUB bootloader and only memory test and windows are showing up.
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 just installed ubuntu 12.04 using a different partition for the /boot (I don't know why exactly I did this, I remembered reading somewhere on the web about this). The thing is that after this operation, the grub is not showing at boot, so the computer is loaded directly into windows.
A common problem, I know, but nobody seems to have a clear cut solution.
I don't want rEFIt. It doesn't work right on my quad-boot setup since when I installed grub on /dev/sda5/ it wouldn't boot Linux right.
....Anyways.
Although I have several kernel versions in /boot and having them in my grub.cfg, they are not displayed in the grub boot menu.
Running update-grub seems to work, as it puts the kernels in the grub.cfg in /boot/grub.
After I installed mythbuntu 12.0.4.1 to a usb drive I was getting error out of disk and no suitable mode found. After showing these errors for a few minutes it would finish booting. I read that if I uncommented GRUB_TERMINAL=console in /etc/default/grub and ran sudo update-grub that should fix the error. Well now it won't boot to mythtv at all. It just boots to a grub prompt.
Hi,
For some reason my laptop is not showing my hidden grub menu, either the splash to let you know that grub has loaded or the menu itself by pressing the escape key.
I just got back to my house and found that there was an update for GRUB (to 1.99-21). Since it's a GRUB update I thought "why not" and went ahead and installed it. As it was nearing the end of the installation, it brought up Debconf where it asked me which devices I wanted to install GRUB on (see Image 1).
After recompiling my kernel, I copied the corresponding files to /boot, and my /boot directory looks like:
Then, I inserted a new item in grub, and /boot/grub/menu.lst now looks like:
After searching a lot, I found that someone mentions that maybe ACPI settings matter. So, I set ACPI to off.
