I just created a disaster I would not have thought possible. I used a USB stick to install Ubuntu 12.04 LTS alongside Windows 7 on a Dell Inspiron 560.
The install went well, except that GRUB didn't install.
i installed ubuntu 12.04 server onto an older pc i had laying around and am getting a grub screen and when i go to boot ubuntu i get a blank screen and then the tv loses the signal from the box. its hooked up rgb and did work fine with 10.04 but i havent booted it up for about 2 months so wasnt exactly recent the last known good boot.
I just installed a fresh Ubuntu 12.04 and during install selected to have grub put on it's own partition for the boot device since I use the Windows 7 boot manager for my booting. I also boot Ubuntu version 10.04 with the 7 and 12.04. I use Easy BCD to configure the boot menu, and did add in my new 12.04, but when I select it to boot it re-directs to the 10.04 grub menu.
I just did a fresh install of Kubuntu 64 bit 12.04 (from the DVD) to a Lenovo V570 laptop.
I did a dual boot install with Windows 7.
Lately (at least the last 2 time I turned the PC on) I noticed grub takes forever to boot. I timed almost 9 minutes between the bios messages go away and the kernel log appears on screen.
The question is how can I know what grub is doing or waiting? How can I check grub is ok?
A few days ago I removed the splash screen so I see the text log on every boot.
I've installed yesterday Ubuntu 12.10 32-bit version (as recommended) on my laptop. It was a fresh install, alongside Windows XP. On grub, after choosing normal boot on ubuntu, it starts loading things, but before starting the Ubuntu loading screen (with the dots) it stops flashing HDD activity led, and hangs there, and I need to hard shutdown the laptop.
After fresh 12.04 install my screen was stuck at 1024X768 and Unity only worked in 2D. I fixed those problems by a simple grub edit:
1. Open Terminal and type:
gksudo gedit /etc/default/grub
2. a text editor will open with the grub configuration file.
during bootup, on my system with the radeon kms driver, my displays turn off (both showing 'no signal' messages) between grub and lightdm.
grub displays normally, lightdm graphical login displays normally and x displays and works normally.
