I have installed Ubuntu in my system.After a forced shutdown i am unable to boot into my system.when booting via recovery mode its failing in file system check.Its telling "fsck:No such file". But if i boot "normal boot up" its booting up and i am able to login.After logging in, nothing is getting displayed.Just a blank screen comes up.After sometime screen saver comes.If i press any button desktop screen appears but no folders are displayed.
I installed LinuxMint on an external harddisk. I shutdown the laptop and removed the external harddisk. Then when I restarted the laptop (external harddisk was not attached).
Error: No such device <hex number>, Grub Rescue>
The laptop showed me the above stated error. Now I am not able to boot any OS on it until I reconnect the external harddisk!
I am new Linux, but have already installed a new HDD in my PC and successfully installed Fedora 14. Unfortunately, I am unable to configure my system for dual boot and my PC always boots right up into Windows Vista which is the original OS on my original HDD. I have searched the web, but only find examples of splitting partitions and dual booting into different versions of Windows. I apologize for the simple question, but I am certain that someone in here can point me in the right direction. My intention is to migrate to Linux entirely, but want to learn Linux before completing a full migration.
I have to haredisk in my system "sda" and "sdb" in sda there are 2 OS installed which are RHEL5 and windoesXP
Now I tryed to install Ubuntu and it got installed successfully.when I reboot my PC I found that my RedHat grub has got crashed.
I Again booted my system with RHEL5 DVD and entered in that rescue mode and and installed that Redhat grub (grub-install /dev/sda(#pwd /boot)) and when i see my system after getting reboot that Ubuntu grub was missing
This issue as my requirment is that i want my system to detect all that three OS which are installed..
I have a PC with 4 harddisks and one ssd drive, presently PC boots from the 1st harddisk and other harddisks (sometimes 1, 2 or 3, depends upon the requirement) are used for the storage. Now i want to boot the PC from SSD and use the other harddisks for the storage only. My problem is that when system boots it takes 1st harddisk as sda and SSD as sdb, if i am using only one harddisk, and if i use 2 harddisk it takes sdc as SSD. So i am not able to give fix boot point in menu.lst file, if i wish to use root filesystem from SSD.I am using 2.6.33.7 kernel and grub bootloader. I have tried using initrd with udev but not able to include and start udev properly in initrd. I am trying to boot from UUID or LABEL, but no success. Am i missing something in kernel to get the UUID or LABEL.
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.

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 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!
I just recently installed ubuntu 9.10 in my upstairs computer. It is a single boot system.Downstairs I have a dual boot system. I have windows vista and ubuntu 9.10 installed. It worked fine. I wanted to make this a single boot system and uninstall ubuntu 9.10. I cannot get rid of the grub bootloade
I have installed centos 5.3 64bit on my machine using pendrive. installation completed successfully. but now i am not able to boot my system without pendrive. do i need to make change in /etc/grub.conf
I have dual boot (wubi) Windows XP. It was working smooth until I upgrade ubuntu 9.10. At the boot screen I choose Ubuntu, then it ask me wich version, then it freeze. I tried the recovery version, but then it ask me for a user ID login and password. At this point I'm able to enter the user , but it don't type anything on the password and keep asking me to enter the user id and password again, and again.
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 entry to boot it and it attempts to but after a few seconds gives me the error "unable to mount file system....a maintenance shel will be started" Where do I go from here? to figure out whats going on?
After a kernel update action, it seems that I'm unable to boot a system anymore. First off, after installing the kernel, and trying to shutdown to boot to the new kernel, the system replied with INIT: no more processes left in this runlevel. Kernel update was performed from to the following versions 2.6.18-128.el5.img -> 2.6.18-164.11.1.el5.img . The system is a VMWare virtual machine. When trying to reboot, the system passes GRUB, starts initializing and after loading the dm it stops for a few seconds at the message Waiting for new devices, show the following message:
Setting up new root fs no fstab.sys, mounting internal defaults. After this and a few other messages, it displays : INIT: version 2.85 booting INIT - No more processes left in this runlevel INIT: Id "x" respawning too fast : disabled for 5 minutes And then it just hangs. This is the output of my inittab:
[code]...
The system boots into failsafe, but still shows the errors mentioned.
I recently installed Ubuntu Netbook Remix (10.04) on my brother's Acer Aspire One (751h) netbook, set up to dual boot with XP Professional. The initial install was successful, with both OS's booting correctly. However, after a series of updates and module builds (this machine has the Poulsbo chipset, still somewhat of a mess), Grub2 is now unable to boot XP, displaying the error "Operating system not found."
To be clear, grub works properly (aside from not booting XP), so the MBR is intact, although I've rerun grub-install to be safe. Restoring the windows MBR (using testdisk) boots XP happily, but of course ignores the ubuntu installation. I also had testdisk rebuild the NTFS boot sector, to no change - grub still doesn't work, the windows MBR does. Using the grub console, I can "root (hd0,1)" and see files on the XP partition, but "chainloader +1; boot" again fails with the same error. The ubuntu install can likewise mount the NTFS partition with no problems.
Given the fact that switching the MBR fixes the issue, I'm suspecting a Grub2 configuration problem. However, the simplicity of "root (hd0,1); chainloader +1; boot" leaves me stumped as to what that could be. Also, the error text "Operating system not found" is suspiciously identical to my BIOS's error message when attempting to boot from a non-bootable medium (as I found out while attempting to make a bootable usb stick with my mac).
I am having 320G of HDD , on the HD i m having 40G free space when i m trying to install rhel5.4 in the free part it is showing me this error
Could not allocate partitions as primary partitions: Partitioning failed: Could not allocate partitions as primary partitions.Not enough space left to create partition for /boot.
I have just had an auto-update, and the process has stopped with the warning above. The full error message is given below. I had already had problems (not sure if they're somehow resolved or related to this) with updating [URL]. Tests have determined that problems in the boot system exist which prevent migration to dependency-based boot sequencing:

So 2 days ago everything was all fine on my machine. Has been for about a month, but all of a sudden as of yesterday I have no sound, I am seeing IRQ interupts on boot, During boot I am seeing file system is not clean, , and swap space is being used for the first time while doing normal task, etc. These are 2 new hard drives in RAID 1 with ReiserFS. I should have used a newer FS but thats a whole other argument.
Anyways here we go. The system is Debian Lenny amd64 Physical RAM 4GB + 6GB swap /var/log/messages

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:
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:
The problem is this: I have a 320gb HDD splitted in 4 partitions. When I first installed Windows XP I formatted the HDD in 3 (Windows system partition, Media partition and another one I left for Linux). However Linux requires another partition for swap. Everything was just fine. One day Windows stopped working and I tried re-installing it. After the system was ready to start, Windows failed to boot with "NTLDR is missing" message. I tried to recover the Master boot record, even replaced NTLDR manually - nothing worked. I read that in order a HDD to be partitioned in more than 3 parts the so called "extended" partitions must be created. I think this may cause the problem but I don't want to wipe out everything (I have more than 100 GB of books most of which are not available anymore in the same locations I have downloaded them)
Suppose I have 2 hard drives, each with 4 partitions. One hard drive has OpenSuse 10.3 on one of it's partitions, and the other hard drive has Ubuntu 10.04 on one of it's partitions.
I would like to know if it is possible to boot from a System Rescue CD or Parted Magic (CD), then look over the hard drives and partitions with a partition editor, then choose one Linux partition, and "boot that distro". Somehow, I suppose, control from the live CD would be given to the chosen hard drive system ???
Reserving the right to ask follow-up questions :-)
I've created LVMs, and use this after I have added new disks to the system. df -h give me some lines, and one of them looks like this:(this is the system which holds backup files - and I want to disconnect it from time to time to create a duplicate backup)
Problem: When I disconnect this drive, the system will not boot. Gives me the "enter password for root" or click control+D to continue. How can I get around this check - if the disk fails to load, or have been taken out.
lately i notice that when i add a new user withthe useradd and passwd command, and then try to login using this new account, am being prompted with a message,saying ' you cannot access /home/newuser. that the account doesnot have permission on his home directory. i have even tried go give the user(john) ownership over his home directory with the #chown -R john:john /home/john
I have an MSI-RC410 motherboard with onboard ATI Radeon XPress 200 series Graphics card.
I have used OpenSuse-11.0 on my PC for over an year. but when I tried to upgrade to OpenSuse-11.1, I managed to install it only to find that several features were missing. for example /dev/cdrom was missing.
Also install DVD of Fedora 11 did not work.
I have also tried Ubuntu-9.10 live cd. When I boot from the CD i get the initramfs command prompt. Still able to install old versions of these OSs.
What is the reason for this behavior?
Does it have to do anything with the new version of the linux kernel not being compatible with my hardware?
What should i do to install new versions of Linux?
Per my request my son installed XP and Ubuntu(interested in learning Linux)in my computer. The installation went well and I was able to choose the system I wanted to work in from the menu. It worked for several months but now when I choose Ubuntu from the menu I longer get to the Ubuntu login screen.
I have Cisco Switch 2960, and it has been configured with dhcp (from 192.168.43.31 to 192.168.43.) and all my client connected to It. I have a modem and Its IP is 192.168.1.1, I used Fedora Linux system in between Modem and Switch , and made IP forwarding (Only one ethernet port is avaliable in Fedora Linux System), so that I can use the Internet through out the LAN. But When I try to ping modem form client system, I get an message icmp_sep=1109 Redirect Host: (New nexthop: 192.168.1.1), I am not able to connect Internet from my Client system.
I am unable to create either a file or a directory in a specified path in Linux. I am getting the error "No space left on device". I have checked with df -k and df -i. Free disk space is 28 % and free inodes are 28 %. What else could be the reason?
I;m using RHEL5, i have a problem with my wireless lan card, my laptop wireless cant be enable , i always show a inactive in the network configuration property, i know it detect in my box code...
I need to edit the system time as a not-root user. I am carrying out the following actions in my program.
1. Read the User Id of the process. User_ID= getuid() 2. Printing Capabilities(Permitted, Efffective, Inheritable)of the process 3. Setting UID = 0, using setuid(0) 4. Calling the prctl(), function to keep capabilities 5.Switching the UID from root to User_ID of the process 6. What we have now is a process with root capabilities as a non root user 7. On printing Permitted, Effective, Inheritable capabilities, I get the following --> Permitted = 0xfffffeff = Effective Inheritable = 0x0; with UID = 1001; 8. I then try and set the system time with --> system("date -s 10:00"); 9. I get an error: date: cannot set date: Operation not permitted 10. I am unable to understand as to why I cannot set the time even thought the capability bit CAP_SYS_TIME in the Permitted and Effective sets are SET.
