Boot error grubenv USB Drive 11.04
location: ubuntuforums.com - date: May 4, 2011
I'm running 11.04 off of a 32gb flash drive. Something about grub on my install is messed up. When trying to boot after a normal shutdown, I get the following errors.
error: invalid environment block
error: invalid arch independent ELF magic
I think something about grubenv under /boot/grub is being corrupted. Loggin in under Ubuntu 10, I can make my way to the files on the 11.04 flash drive and issue the following commands to make it boot normally (from https://bugs.launchpad.net/ubuntu/+s...b2/+bug/439784 )
# grub-editenv grubenv create
# grub-editenv grubenv set default=0
Why is this file corruption happening? How can I fix it?
Intel Mac booting from USB drive 11.04
location: ubuntuforums.com - date: October 6, 2011
I'm trying to help someone at work make an Intel Mac bootable USB thumb drive (Patriot XT 8GB) for Ubuntu so that they can use it for a class they're teaching next Spring. (Lots of F/OSS discussion in the class, so he wants the students to be able to check out Ubuntu)
I saw the note on the download page about the mac. I followed the directions, and now I've got a USB drive that the Mac sees as a volume. (Of course if I pop it into my Ubuntu machine it says "A Volume with software packages has been detected...." )
I've tried booting the mac using the Option / Alt key, but it doesn't show the USB drive. The Mac I'm using is dual boot (OS X (10.5.8 - and Windows XPSP3). I thought maybe refit on the Mac was causing problems, so I checked another machine (only OS X 10.5.8 - and had the same result. The Mac will recognize the internal HDD, but not the USB drive with the image.
I checked to make sure the USB thumb drive is formatted with the GUID partition scheme. When

unable to boot new installation external usb drive 14.04 or 13.04
location: ubuntuforums.com - date: June 15, 2014
Hi I wonder if anyone can help me with this problem? I have all ready spent ages trying to solve it. My computer is a ASUS M50sv laptop which dual boots windows 7 and Ubuntu 12.04. I have been trying to install 14.04 to an external usb 500gig WD passport drive from a live bootable usb thumb drive. The install goes smoothly with the bootloader being installed to the external drive and 14.04 being installed to the first partition (ext4). There is also a swap partition on this drive. After the install has finshed and I reboot I am unable to boot the external drive by either booting it directly from the bios. This results in the grub rescue prompt with Error:file /grub/boot/i386-pc/normal.mod not found. If I try and boot from grub on my internal drive I get error: file not found load the kernel first. i have searched and searched and have not been able to find and solution to this. Any help with this would be greatly appreciated.
Many Thanks. Al-Man

boot error from usb startup disk
location: ubuntuforums.com - date: December 26, 2010
I'm trying to boot from the usb startup disk I've just created. It pretends to load once I select it from the ReFit menu and says "boot error". I wonder why it won't boot (maverick)?
[SOLVED] Boot problem after installing Ubuntu 11.04 "Kernel panic not syncing VFS"...
location: linuxquestions.com - date: December 16, 2011
So I upgraded to Ubuntu Desktop v12.04. After doing so, I'm unable to boot the machine.
The complete error message is:
11.10 slower to boot and shut down than 11.04
location: ubuntuforums.com - date: October 22, 2011
One of the things I liked about 11.04 was its fast boot time and particularly fast shutdown time. I especially enjoyed showing off the shutdown time to Windows users - great for a quick getaway at the end of a hard day's work!
So I was disappointed after upgrading to 11.10 that it's both significantly slower to boot into a working state and also to shut down. I've upgraded 3 computers from 11.04 to 11.10 and they're all slower - shutdown now takes 14-15 seconds compared to just 4. On one computer I noticed it says it's failed to 'ask' a process to terminate and I guess it then times out and kills the process(es).
Has anyone else noticed these slower startup and shutdown times compared to 11.04; and is there anything we can do to get it back to approaching 11.04 performance? (I see someone else has noticed the slower boot speed.)

how to make a DOS boot CD or USB drive?
location: ubuntuforums.com - date: October 7, 2012
I need to update my Bios and the first step will be to boot into DOS. I'm sure this is covered out here, by=ut searches haven't found it. Either a CD or from a USB drive is fine. Thanks! (And simple, non-terrifying procedures are appreciated.)
