Hello all, I've got an Asus Eee which came with Windows XP. I created a partition (in Windows), then installed Ubuntu 10.10 Desktop Edition using their Windows Installer.

ACPI Error when trying to install Ubuntu 12.04 LTS from USBstick

location: ubuntuforums.com - date: September 7, 2012
Hi! It feels like I've Googled this for several hours now without getting any smarter. I just built myself a new computer, and of course I want to run Ubuntu on it. Components: Motherboard: ASUS P8Z77-V Pro CPU: Intel Core i5 3570K 3.4 GHz GPU: MSI GTX 560Ti OC RAM: 4x4GB Corsair Dominator 1600MHz What happens when I try to install Ubuntu 12.04 LTS 64bit from my bootable USB-stick is that the install starts to load up normally, then after a few seconds it gets stuck at some message like "ACPI Error yadayadasomethingsomething" (not close to that computer right now so I can't quote it fully). What I've found when Googling is basically just people saying that one should try to install with acpi=off. Is there any danger in running Ubuntu with this on a daily basis? Also, how do I add this acpi=off parameter when installing from a bootable USB-stick? I'm a complete noob when it comes to Linux and Ubuntu, all I know is how to compile Android from source,

Error when installing ubuntu 12.04

location: ubuntuforums.com - date: June 14, 2013
I am trying to install Ubuntu 12.04 but every time I try to install it I get an error the error says. Error informing the kernel about modifications to partition /dev/sda1 - device or resource busy. This means Linux won't know about any changes you made to /dev/sda1 until you reboot- so you shouldn't mount it or use it in anyway before rebooting. The pop up window has an ignore button and cancel button but I cant get out of the window I have to restart the computer. Has anyone seen this issue before?
