Ubuntu :: Unable To Boot Into OS
Apr 10, 2011
I am currently running Xubuntu on a flashdrive. However, I just bought a 1TB hard drive, which I partitioned in half to use for Ubuntu. I successfully installed Ubuntu from a CD I burned with Xfburn. Whenever I try to boot to the Ubuntu partition, I get to the GRUB menu(Run Ubuntu, Run Ubuntu Recovery Mode, etc.). I choose Run Ubuntu, then my screen goes blank. I hear 2 quick drum beats, and then my monitor goes into standby - indicating that it's not doing anything. Why can't I boot into Ubuntu?

I switch on the PC and it loads the Grub splash screen. However, it does not automatically boot the top entry after two seconds as it's supposed to and just hangs. I hit enter to boot it and it attempts to but after a few seconds gives me the error "unable to mount file system....a maintenance shell will be started"
This occurred after I was using it and then everything suddenly froze up on me and I had to crash out Now this!

Environment: A 32-bit kernel RHEL5.3 system running on a virtual machine. The root(/) filesystem is on an LV.
Issue: Unable to resize the FS after extending the root LV since it is mounted. After extending the LV, online resizing of the FS was not supported and the root filesystem could not be unmounted while it was in use. On rebooting, I got a kernel panic error. In runlevel 1, I couldn't run chroot, couldn't find the /etc/fstab, root FS could not be mounted, fsck did not run (tried block 31 for second copy of superblock using dd count=1 bs=4k skip=31 seek=1 if=/dev/sda2 of=/dev/sda2), couldn't find any rpm on installation media to install unix-utils rpm. On running commands in runlevel 1,
I got the following output.

I am trying to install ubuntu 10.04 on windows7.windows 7 was already installed.I ollowed these steps to install ubuntu 10.04.1)First i made some freespace in hard disk to install ubuntu using windows7 default options(By shrinking).2)I used USB drive to install ubuntu.I made it bootable using unetbootin.3)I followed normal steps install(language,area,keyboard,using manual partition i installed ubuntu in free space,etc).4)I got boot menu when it restarted.PROBLEM isAs long i use only ubuntu (boot into ubuntu --shutdown--boot into ubuntu --shutdown) it works well.
If once i boot into windows 7 and restart the system i am loosing boot menu options.The following error i am getting"no module name found Aborted.Press any key to exit".If i press any key,I guess its trying boot using internet and lastly it says Operating system not found and hangs.

I am running the latest suse release downloaded directly from their website. I ran the installation after buring the dvd and everything seemed to be working fine. after the installation i ran updates and used it for a little bit. When i shut it down that night and went to restart it I got an error that stated the OS wasnt there. I then went through the installation and everything and it retained the information from the installation before (web history etc.) but for some reason every time I reboot or shut it down the system is not able to read the startup information from the hard drive and will not come on without me re installing it.

I have Ubuntu 10.04 LTS and Windows XP installed on my laptop. Usually when booting, I get the GRUB 2 menu and I can boot into either Ubuntu or XP.I was playing around with EasyBCD, then after trying to remove it I was unable to boot into Windows, I used a Windows 2000 CD recovery console to fix the MBR (using: fixboot and fixmbr).Now Windows starts up when I power on, but I don't get the grub menu anymore with an Ubuntu option. If I boot from the Ubuntu Live CD and try to mount my Ubuntu partition (/dev/sda5) I get this error:
mount: wrong fs type, bad option, bad superblock on /dev/sda5,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try

After installing karmic with Grub2 I am unable to boot into Archlinux partition. Grub2 has removed the last line of the Archlinux boot stanza! It used to read:-

Following the Grub2 tutorials I have tried editing /etc/grub.d/40_custom as follows:-

But no luck. Only way into Archlinux is to get into the edit shell and manually add the missing line and remove other stuff not needed. I have spent hours trying to resolve this issue and I am fairly p----d off

I can only use the Live CD to operate Ubuntu. After typing in the command sudo fdisk -l, I get the following?
Disk /dev/sda: 320.1 GB, 320072933376 bytes
255 heads, 63 sectors/track, 38913 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

And when I boot without the Live CD, I get the following message in the GNU GRUB Version 1.98-1ubuntu7 window page.

I had a dual boot system with 3 partitions, Windows 7 on one partition, and Windows XP on another partition and a Data partition. I decided to load Ubuntu 10.10 on the Windows XP partition.During installation I selection manual partition, and deleted Windows XP.after successful completion of Ubuntu installation "Grub" directly boots into Ubuntu, it doesn't show me the OS selection screen. After following some forum posts I did an update grub
Code:
Generating grub.cfg ...
Found linux image: /boot/vmlinuz-2.6.35-22-generic
Found initrd image: /boot/initrd.img-2.6.35-22-generic

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 VPCZ13C5E with Intel Core i7 M640 @ 2.8GHz and Windows 7 Prof 64 bit.
It has 4 x 122GB SSD's in one Volume type Raid 0 using Intel Rapid Storage Technology.
The installation prog did not offer to install alongside an existing (Win 7) system, however after installation I was able still to boot Win 7 from the Grub Menu, but the Linux option just gives the black screen of death.
Booting from the 10.10 LiveCD and running sudo fdisk - l gives "unable to seek on /dev/sda". Also I have had a message "unknown filesystem type 'isw_raid_member' although I have forgotten where that came from!
The LiveCD shows that the filesystem does seem to have installed OK on the ext4 partion of 100Gb which I had kept for it, however it will not boot.
The results of Boot_info_script are shown in the attachment Results.txt
I have tried sudo mount /dev/mapper/isw_dijbjabefg_Volume07 /mnt and it gives no errors.
I then tried sudo grub-install --root-directory=/mnt/ /dev/sda which gave no errors but when I reboot and choose Linux the result is still the black screen of death.
I understand that the problem may be one of Ubuntu drivers having to catch up with the latest technology but given that Ubuntu can partition the swap file and the ext4 system I seem to be so close.

Im having a serious issue with booting ubuntu 10.04, the issue being it wont boot up at all, after working so well for so long (i suspect some recent dodgy system updates are responsible) so I decided to just reinstall ubuntu from scratch again but wanted to retrieve some important files from my root device. So I am running the live desktop and I can see my previous filesystems under places but cannot mount or open my original root device where the files I want to recover are located, I receive this error msg:"Unable to mount 77 GB Filesystem.

Dual Booting my laptop and unable to change the Boot Records on the drive. Not because I dont know how, but my primary OS will fail to boot(win7).
I have drive partitioned as follows...
sda1 = Win7 system (default install)
sda2 = Win7 Main (default install)
sda3 = swap
sda4 = Extension (I think thats what its called)
sda5 = / (ext4)
What I need is a boot cd or perferably Grub installed on a 256MB Thumb drive with the options to load the installed system from sda5.

Having a major issue with my laptop. I am unable to boot into my Vista installation.I am currently posting this through my Fedora 11 installation which I had already. If anyone is interested, the BSOD error is:
0x0000007B (0x80399BB0, 0xC0000034, 0x00000000, 0x00000000)
As far as I know, a '7B' BSOD is usually a hard disk error but I am 100% sure the HDD is fine as I can read and write from both Fedora and Knoppix without issue. Steps taken so far: Obviously, I have tried the usual steps of trying to start windows in safe mode, last good config, and all of the F8 options. When they failed, I used fedora to check for some solutions online (Mostly useless answers from MS) and I found one successful case when a person flashed his BIOS back to an earlier time. Unfortunately, I cant get the BIOS update I got from the Dell website to boot from a USB drive (Says invalid boot disc - the BIOS on it is in the .exe format which I can't use in linux) and I do not have a floppy drive on the laptop.
So, I put in my Dell drivers and utilities CD hoping that it would give me some option to update (Or roll back) the BIOS but there was no such option. However, it did give me a load of diagnostic options including repair options by symptom so went with the "Unable to boot from BIOS". Unfortunately, that didnt help me at all. So, I got my Vista installation disc (OEM supplied) and managed to get to the repair menu (Which I had among my F8 options anyway) but this also has the option to reinstall. Unfortunately, it states that "Upgrade is unavailable" and that a clean install is the only thing I can select (At the expense of my files and settings).
As for the repair options, the automatic recovery doesn't seem to find any errors, asks to reset and see if all is well (It isn't). For some reason, system restore doesn't detect any restore points. There are no windows memory errors detected and I have no backups. So, i'm left with a command prompt that, by default, is asking for a file in this folder: X:/WINDOWS/System32/ I have no idea where it is getting the X: drive from - I have C and D drives for windows only. As per another online guide, I tried:

in my ubuntu installation i had allocated about 15 GB for the /home folder. today i was trying to increase the memory in my system and so using the disk utility program of the 9.10 release, i formatted the /home part of the drive and gave it another name and started using it as just another ext3 partition to store my files. when i restarted the system, ubuntu wouldn't start and it takes me to the maintenance shell.
i have no idea how to solve this problem from the maintenance shell. i also have win XP in my system along with 9.10. i can't afford to lose either of them. i've got many expensive applications installed in both OS. so i can't reinstall Ubuntu in my system. is there any way to override mounting the /home part and start ubuntu.

I installed Ubuntu 10, deleted my windows O/S, updated and rebooted with everything working fine. When I shut down completely and start the computer again, I get a "Minimal BASH-like line editing is supported". I then get a grub> and nothing further. I have done this 3 times and get the same results. I would appreciate some direction. Do I have a computer problem or is there a work-around to get the system to boot?

Two days ago, my computer was working fine. Yesterday, I booted to a screen that displayed this:
Gave up waiting for root device. Common Problems:
-Boot args (cat /proc/cmdline)
-Check rootdelay= (did the system wait long enough?)
-Check root= (did the system wait for the right device?)
-Missing modules (cat /proc/modules: ls /dev)
ALERT! /dev/disk/by-uuid/<long number> does not exist.
Dropping to a shell!
Then it dropped to a busy box.
I hard restarted and it opened to a linux kernel menu. When I selected the older one, it opened perfectly. Today, however, I did the same thing and now the old one opens to the error message.

AMD Phenom II x4 955 clocked to 3.7 ghz
4 gigs DDR3 1333mhz Ram
Nvidia GTX 460

I am rather new to Ubuntu but have been able to boot from cdrom on this PC before, and have it run " under Windows XP Home". Due to age of PC Ubuntu ran in a degraded mode. That was 2 years ago and The Verion was not 9.04. I tried to install Ubuntu 9.04 on this PC again (Dell Dimension 2400) and do not have enough space. I get a message that Windows XP will be wiped. My friend built me a PC with Windows XP Pro. It has plenty of space. When I put the DVD 9.04 v. that came with my Beginning Ubuntu Linux book, I get to a point where I see message: "BOOT FROM CD?DVD. I hit a lot of keys but nothing happens and Windows starts up. The device I am trying to boot from is a Model GCE-85208 year 2003.

I've got Ubuntu installed on my computer but my brothers want Windows XP back. I have the XP disks but when I reboot the computer and it says Boot from CD press any key. I press any key and it doesn't boot, Ubuntu just loads. I tried to change the Bios by pressing F12 but when I get in the menu it won't let me choose. I press the up and down arrows and nothing works. How can I install using the XP disks?

We've got an old pentium computer dual booting Ubuntu and Windows XP. We've purchased a PNY GeForce FX 5200 256MB 128-bit DDR PCI Video Card for it. After installing it, we had full access to the XP and installing drivers from there went without a hitch and appears to work fine. When we tried to boot into Ubuntu, all we got was the (initramfs) prompt, and we're both relatively new to the fantastic world of Linux and so we have no idea what to do with it and finding information concerning our issue has been fruitless, as we can't seem to find anyone that has had a similiar problem.
We then uninstalled the card, booted up Ubuntu and tried to install drivers via administration>Hardware Drivers, but the computer doesn't appear to have any on board graphics, and so Ubuntu won't allow us to use any of the drivers in the hardware drivers (via administration). We then did a tonne of research and followed a few tutorials for installing Unix drivers from the Nvidia web site.
One of the tutorials that we followed involved doing a Control+Alt+F1 and then shutting down the GDM to install the new drivers. After installing the new drivers, we for what ever reason, couldn't restart the GDM. After what appears to be a failed attempt at installing the driver, we cannot access the desktop and are now presented with the following message (when booting in normal kernel mode): "Ubuntu is running in low-graphics mode. The following error was encountered. You may need to update your configuration to solve this. (EE) No devices detected.". The only 4 options are:
#1)Run Ubuntu in low-graphics mode for just one session. This results in a black screen without a prompt, Control+Alt+F1 gets us a prompt in the top left of the screen that isn't flashing and we can't do anything at all.
#2)Reconfigure graphics. This gives us three options of which we have no idea what to do with:
1) Use default (generic) configuration,
2) Create new configuration for this hardware,
3) Use your backed-up configuration, along with the OK and Cancel option, which, the latter option takes us back to the original 4 options.
#3)Troubleshoot the error. There are four options here:
1)Review the xserver log file (no idea what to do with this),
2)Review the startup errors (no idea what to do with this),
3)Edit configuration file (no idea what to do with this),
4)Archive configuration and logs (which has been done).
#4)Exit to console login. (gets us a prompt in the top left of the screen that isn't flashing and we can't do anything at all). We are in dire need of some guidance, before attempting any of the options in "Reconfigure graphics" , as we have no idea what to do with any of it and recovery mode doesn't get us anywhere either.
