Ubuntu :: Laptop Boot Failure - Invalid Enviroment Block - Unable To Load Default Boot Entries
Mar 3, 2010
Have been running ubuntu for sometime now and love its functionality...However since a recent update have the following issues..When I power on the laptop I get the toshiba logo followed by grub loading with the message ' invalid enviroment block" "unable to load default boot entries". When I then try to run the laptop off a LiveCd, the ubuntu splash screen appears with the loading process bar (horizontal line) displayed..however it then appears to display a black screen with no further activity..Now all of this is via an external monitor as my laptop screen shows no activity right from the very start with just a blank screen....so am really stuck here wondering if its a harware/software issue or a combination of both...

I have a SONY laptop, PCG-7181M model. It came with Windows 7 but I changed the OS to Ubuntu. Last night it asked me to upgrade to the new version called Natty Narwhal. I had to go to bed so I changed the sleep timer on the laptop to 2 hours, the time it would have taken the upgrade to complete. I woke up and the laptop was off, now only the grub menu shows up and the laptop won't boot. I tried doing this: - When the machine boots up, press Esc to get to the Grub menu - Select one of the recovery mode options. This will boot you up to a single-user root prompt. - Run sudo fdisk /dev/sda (this assumes that your hard drive is at sda) - Type p to see which hard drive partition is labeled Linux swap. In my case the partition was /dev/sda5. Type q to exist fdisk. - Type these commands:

I just upgraded to F15 and it went well. But at the next and each subsequent cold boot the BIOS reports "Your system last boot fail or post interrupted Please enter setup to load default and reboot". The board is an asus P5N-D. I press F1 to blow past the error and all is well until the next cold boot. Restarts are fine, no errors at all.

My laptop died while installing F12, without completing installation. Now I can not boot the computer from HD, CD, or USB. I have flashed the BIOS with the most recent ROM. I can access the BIOS setup and exhausted all my options there, which is mainly boot order. At the moment, the boot process goes to a blinking cursor and does not allow for input. The laptop in question is a lenovo Y510 that was previously running F10 with a single partition.

I recently installed Ubuntu 10.04LTS on my computer and realized I wanted to give 11.04 a try. So, using the Update Manager both times, I applied all updates then upgraded to 10.10 then to 11.04.
Here's where the problem starts. Grub loads fine. I choose Ubuntu. I briefly get a purple splash screen then a black screen with some text that looks like Ubuntu is trying to load (I've attached a picture of this screen). This screen flashes a couple times then stays up and nothing happens afterwards. I can input text and commands but I get no response. Not even an "invalid command". The only thing I can do is press CTRL+ALT+DEL and my computer will reboot.
I have Ubuntu installed alongside Windows 7 on a 50Gb partition (plenty right?), AMD 64-bit dual core processor, and an ATI Radeon HD 3200 graphics card. This is on an HP Pavilion dv3 laptop.

This morning my update manager came up so I clicked to update. About halfway through the update an error message popped up & said to restart my system. I restarted my system and now have a black screen with the following message:
mountall: symbol lookup error: mountall: undefined symbol: udev_monitor_filter_a
dd_match_subsystem_devtype
init: mountall main process (344) terminated with status 127
I read around earlier & tried to use a Ubuntu disk and reboot but I have the same error.
I'm using a Dell Inspiron computer, it's just over a year old. I keep up with all the updates but unfortunately cannot say for sure which updates were taking place because I just hit the update box.

Last night when I turned on my lap top (5 year old Acer TravelMate 4650), it was not able to boot up (10.04 LTS). No system files could be read and a lot of error messages was displayed. In fact, it has done a few checks for disk error lately during boot up, but no further warnings given. I gave up recovering, and simply re-installed Ubntu 10.04. I was wondering if this could be related to a virus attack?

I recently lost the default panel from the top task bar, a message appeared on boot up saying a config file was missing or couldn't load - or something to that effect. I didn't realise to what it was referring until the computer (an Acer One) completed its start up and I could see the desktop
How can I restore the panel? (graphic from my other Ubuntu laptop attached showing the default panel appearance)

I installed Debian 5.03 Lenny successfully on my machine. I got this error during boot: ACPI : invalid PBLK length [5]. After that the Operating System boots properly and starts normally. What does this error statement mean? Is it safe to work with this installation despite this error?

A few weeks ago I installed Fedora Linux 64-bit on my HP dv4-1428ca laptop which was running Windows 7. At that time I created a Live USB using the fedora-live usb tool and it booted fine. A couple days ago I decided to try out openSUSE, so I downloaded the 64-bit live-cd image and tried to create a live usb using the SUSEStudio ImageWrite provided in the documentation. The tool kept giving me an error message, so I decided to try unetbootin instead. However, when I tried to boot the live usb on my HP laptop, it presented me with the message.
"SYSLINUX 4.04 EDD 2011-04-18 COPYRIGHT (C) 1994-2011 H. PETER ANVIN ET AL" with a blinking cursor and nothing else. I've tried a variety of alternative programs for creating live USB's (pendrivelinux, linux live usb creator, unebootin), and verified the checksum of the iso file for openSUSE 11.4 64-bit, and still was not able to get past the "SYSLINUX..." message on my HP laptop. However, the live USB does boot on the other computers in my house. Interestingly, if I create a live USB using the tool provided by Fedora, it will boot fine. However the Fedora Live USB tool cannot be used for other distros.
Specs:
AMD Turion X2 Dual Core
4GB Ram
ATI Radeon 3200 Graphics
320 GB Hard Drive

A few days ago I went to perform the Service Pack 1 Upgrade for Win 7. This crashed out with an error. On researching the problem I found a solution to fix the problem by marking the Windows partition as active. I did this (via Computer Mgmt -> Disk Mgmt). This allowed the SP1 upgrade to work, however on reboot I got an error BOOTMGR missing. This I rather rashly resolved by using the Windows 7 install DVD in Recovery mode to reinstall the Windows Boot manager via bootrec /Fixboot I thought I would then be able to use the Opensuse 11.2 install disk to fix grub.
I use the Opensuse install disk and select Repair system -> Expert Mode -> Install New Boot Loader then select Other -> Reread Configuration from Disk. This adds Win 7 back into the grub menu. I then select OK and get the message "the bootloader was installed successfully". The problem then comes when I click my way through OK and Next to finish the install. At the end of the process I get the message "An error occurred during the installation" and I'm no further forward.
FYI the PC has a single SATA disk installed partitioned as follows:
dev/sda1 100Mb Win System Parkition
dev/sda2 Windows NTFS
dev/sda3 Windows FAT

I started installing the beta of Maverick a few days ago, but the update server was running inordinately slow, so I canceled it. Several times, I have attempted to continue the installation, but I've been unable to reach the server. Shortly after this happened, I could no longer boot normally--I get the error:
Code: Kernel Panic - not syncing:VFS:Unable to mount root fs on unknown-block(0,0) Choosing the previous kernel fixes the problem.
So, I obviously want to upgrade to the release version now. When I open the update manager, I get asked if I want to do a partial upgrade to complete the install. I'm a bit leery of doing this since I only have one previous kernel to go back to (my list got really long and I have another operating system entry underneath, so I set my automagic boot manager to only keep two), and if I can no longer boot after the upgrade, I'll have to use Windows until it gets fixed... So, should I finish the upgrade, try to troubleshoot the error, or do something else to jump right to the latest release, after being partway through the upgrade?

I 'm using Ubuntu 10.10 with Gnome environment and mostly as a graphic environment (i don't have knowledge on source codes)..The error message that i get when i try to install the menubar is the following: Package dependencies cannot be resolvedThis error could be caused by required additional software packages which are missing or not installable. Furthermore there could be a conflict between software packages which are not allowed to be installed at the same time.

A colleague of mine was studying at the University of Vienna and saw an application which was based on linux whereby other pc's booted from it and if on the server they had set it to force a clean install on that PC it would download and install a windows image. Does anyone know of the app or could point me in the direction of a similar app.

I tried to do my parents a favor by installing Ubuntu 9.10 alongside WinXP on their PC -- same configuration I have on my desktop at home. The install went fine, but since I made a poor buying decision on purchasing a MSI motherboard in the past, Ubuntu immediately crashes after boot (other MSI board users having the same issue, no help from MSI).
The computer tries to boot Ubuntu by default unless something else is selected from the boot menu. How do I change the boot preference from default (choice 0) to WinXP? I tried manually changing this (editing the grub.cfg file), but the file said not to edit, that it's generated by something else...How do I have WinXP load by default instead of the broken Ubuntu?

My comp came with Vista and then I installed Ubuntu, so it's dual boot. When I start up the computer, it eventually opens a screen with the options to boot Ubuntu, Vista and 3 other partitions. Ubuntu is at the top, Vista at the bottom, and it gives you five seconds to pick an OS or it automatically starts Ubuntu. This is very annoying because I almost always need Vista and I have a habit of pressing power and walking away and letting the computer load. Is there a way to have Vista be the default selection?
