I have installed 12.04.3 LTS 64 bit desktop.
I wanted/needed to install 32 bit desktop of the same release, so I chose the button to install alongside the existing installation.
When I reboot after install, I can not boot into the 64 bit install anymore
After running the system for a bit, updating some packages and rebooting, the new (32 bit install will not boot either). The symptoms look the same. I end up with a small underscore at the upper left hand corner of the screen. No response to the keyboard that I can find at that point. ... except ctrl-alt-del (which operates as it should, rebooting the system).
The boot starts with a grub prompts screen offering the newest install and the older (64 bit install). IF I SELECT RECOVERY MODE, AND THEN SELECT "RESUME NORMAL BOOT", THE SYSTEM WILL BOOT TO A TEXT LOGIN SCREEN.
I have spent a lot of time though getting things installed on my graphical environment. Yes, the text login will show me my system name and mounts everything for that install (that I am aware of). The text install also gives me virtual terminals. Alt-F7 shows me a last line of "Saved ALSA miser settings detected; aumix will not touch mixer. [...]" Not really a clean indication of what is going on.
It seems like maybe a grub issue, but update-grub does not fix it. (or change anything)
I am very tired of reinstalling my system again and again.
When trying to do the "normal" boot, I see the grub screen, large blinking underscore cursor, some text, Ubuntu graphical screen (as I did when the boot was all going well -- I think this called the splash screen), then it goes to the small underscore which does not blink.
I really would like to be able to use my system. The boss is not happy about my loss of productivity.
Please help soon.
