Ubuntu Installation :: Installing Or Recover With No Working System & Defected CD
Oct 12, 2010
I have only a ubuntu 8.10 in my computer, and trying to desinstall some tools and make more free space to do the update to ubuntu 9, I have deleted some system-files (python), and my OS become defected, no internet connexion, no graphic interface,my ubuntu CD is defected too and shows an error like: 'ubiquited error. I can only boot from it, but can not install the install packet which is in the desktop.
I have installed Windows 7 and fedora 12 on my system.I want to reinstall my windows 7 but as I know after installing windows 7 , i will not be able to boot my fedora 12 how to recover bootloader of fedora 12 after installing windows 7. [URL]
before i proceed,I'll like to say that I'm a complete newbie, but enjoying my time with Ubuntu.
Recently, due to hard disk failure, some of the System files got corrupted, I have no idea to which files, but booting Ubuntu from the latest kernel is not working, instead I have to select the previous version from the grub screen.
How to recover these files? Is there a way by which Ubuntu automatically scans and repairs the system files.
OK so I have sony Vaio VPC-CW195s which I bought about about 3 months ago and unfotunatley now my hard drive has been defected by I-astor.sys, I was told that i have to zero fill the hard drive which after doing lots of research I found out that the best way is using UNBUNTU I should use the command prompt to zero fill the drive. I downloaded Unbuntu 10.10 from its own website and burned on a DVD. I put in the CD-drive and the laptop Used the CD to boot and as a matter of fact the unbuntu logo came up, asked for the language (I said english) and then I pressed to use unbuntu without installing then the cursor came up on the top left and screen went black and nothing happened(the laptop was still on it was working). I restarted and this time pushed it to install the same thing happened, the third time I pushed to test for hard drive defects and the same thing again.
I would like to recover my grub installation in a dual boot system. if there is an easy way to recover grub using flash disk? If yes is your suggestion opensuse developed? (currently running 11.3) . It would be nice also to have some gui just to make things easier. If not I assume that then the only option is the boot from dvd. Is that right?
My main hard disk died and I replaced it. After installing windows in a small partition in /dev/sda, I thought I will try linux mint and went for it. (I need windows to play AOE, but ubuntu is my primary OS)I didnt see the options properly or some distraction, I choose the "install alongside windows" option probably expecting it to install it in the unallocated partition next to the windows installation. I had completely forgotten my second internal drive /dev/sdb which has the backup data. Linux mint went and installed itself on that drive.
Is there a way to recover individual files from the second harddrive. Now if I boot or open it through live cd, all I see in the linux mint file systems. I want to aleast recover my CV/resume from the second drive. The second drive is a single ext4 file system The old drive is completely dead, it doesnt even get recognized when I attach it to SATA.
I have (had) Debian Testing running on a 250GB IDE hard drive, partitioned normally.
I also have 4x 1TB drives in a raid 5 using mdadm, and 2x 500GB drives in a raid 1 also with mdadm.
I put the two arrays in lvm using:
I then used "lvcreate" to make storage/backup 300GB, and the rest went to storage/media (approx. 2TB usable). I put an xfs filesystem on both and mounted them.
All was working fine until the system drive shorted out and died on me this morning. As far as I can tell, all my other drives and everything else is fine. I do a daily rsnapshot of the filesystem, which of course is residing on storage/backup (stupid, I know). So I have full backups of everything, but I'll have to put a new hard drive in and reinstall Debian before I can restore everything.
I've reinstalled before and simply reassembled mdadm arrays and remounted them before with no problems, but this is the first time I've used lvm, so I'm not sure what I have to do to restore everything. Is it as simple as reinstalling the system then doing a:
I have two drives in my system with Windows7 installed on the first one (sda) and Ubuntu installed on the second one (sdb). I had to reinstall Windows and now I of course can't access Ubuntu since the MBR was overwritten by the Windows installer.
I followed the LiveCD recovery method described at [url] And it didn't work. When I rebooted after doing a grub-install on sda, I was simply given a Grub command line with no menu or anything. grub-install said it completed successfully and had no errors. What exactly do I need to do to get Grub set up correctly so I can access both OSes?
last week i installed new mint distribution Helena 8 last day i reinstall my Windows XP , now my linux has gone. how can i recover my boot loader ? btw i tried this comands in Live CD:
sudo apt-get install grub
after this command .. this message appears :
Probing devices to guess BIOS drives. This may take a long time.
After a normal shutdown I tried to start my machine but it gets stuck in the login menu and I'm not able to type or move my mouse.When trying to start in the recovery mode, it gets stuck to.Is there any way to recover the system?
Possible Duplicate: How to recover form information for a webpage in Firefox I typed a couple of paragraphs on a discussion board, but when I clicked the submit button, the site was undergoing (un)scheduled maintenance, and the back button decided to refresh the page, sending my paragraphs into oblivion.A quick web search revealed that Lazarus provides form recovery for Firefox. However, installing a plugin requires restarting Firefox, and even after restarting Firefox (which I haven't done yet), Lazarus can't recover forms it hasn't backed up yet.Now that the horse is out of the barn, I want to do the impossible: restore some or all of the text I typed, without restarting my browser.
Edit: I should clarify. Lazarus is a wonderful solution for preventing future form data loss. This question is for people who have already navigated away from their form and lost its contents, but hope there is some way to salvage the situation. My solution was to get a core dump of the process and grep through it, but there might be a layman's way to do it (for example, somehow get Firefox to load the cached version of the previous page). Thus, solutions that only solve the problem in the future, without addressing the present, are off-topic in this question.
I have a 64 bit Dell laptop happily running 10.04 32-bit and Windows 7 booting with GRUB. I want to also install Lucid server on a spare 20GB empty partition and I would like to have Lucid server available in the GRUB menu along with Lucid 10.04 and Windows 7.
I don't want to blow away what I already have working and last time I booted from the server CD to try to install it (9.10), it didn't look as easy as when I installed workstation. Will an install of Lucid server gracefully and safely allow itself to be put on a spare partition and install itself in GRUB or so I need to do this manually? If I lose my Lucid workstation install, I am in trouble.
I have a HP laptop that I have had Windows Vista on for about two years. I am soon going to switch it over to Ubuntu. My question is can you safely use the Ubuntu installation process to delete the Windows partition along with all the programs and files it stores on the hard drive or should you first uninstall Windows manually and then, with a essentially blank computer, install Ubuntu?
I am reinstalling ubuntu mavericks as I could not get the first install to work right. I installed from a CD that I burned. 3/4 of the way through the "installing system" process the screen went dead. The cursor does not respond nor does anything happen with the keyboard. Be aware that I don't know very many things about what a keyboard can do. The screen has been frozen for about a half hour now.
I have an Acer Aspire One running NBR 9.10. A few days ago it "went wonky", wouldn't boot and would just seem to start and then shut off before getting to the logon screen. I managed to boot from a USB stick and run check and fix in Gparted. It found a slew of errors in the file system. Unfortunately, it still won't boot, now it just hangs. I assume some of boot files were damaged.
Now I have two problems:
1. Is there a way to repair the damage? Or just wipe the disk and start over?
2. I need to get my e-mail off of the hard drive. I can mount the drive after booting from a USB stick, but the thunderbird directory is locked. Is there a way around this?
i have one partition of 45 Gb...and other of 250 Gb in which windows 7 has been installed..i booted from ubuntu 10.10 CD and then i chose the installation option on desktop...but when i selected the partition of 45GB for installation..the error message said that "there is no root file system on the drive, set it from partition options"..
I tired to install Fedora 14 using USB, and I could boot with my USB. But, the problem is I can't continued the installing as the system tell me that there are no USB on my Netbook, and when I get the window to choose which sda/sdb content Fedora I didn't find my USB :s
I wanted to install Ubunutu on my laptop and it currently has windows vista installed on it and installed using latest Wubi. I selected Ubuntu from dropdown menu after the system restarted. But when the sytem shows the username page to login the KEYBOARD and MOUSE are not responding.
I am using Lenovo Y series laptop and using the inbuilt keyboard/touchpad.
I was multitab browsing (around 15 tabs) in latest firefox for karmic koala (9.10) and at the same time downloading (probably already auto-installing) in synaptic-package-manager the package: textlive-fonts-extra (and other necessary packages; this was around 90 mb download and 250 mb installation)suddenly the pointer doesn't move anymore, (Alt+tab , and other combinations also didn't work anymore) and I hold the power button untill the computer is turned off,when I reboot I get this message"invalid system disk, replace it and press any key to continue"now I'm using a livedisc to boot the computer (jaunty 9.04)To rebuild the system i think to manually install the packages that probably were interupted while installing and made it not work anymoreThe packages to be installed when text-live-fonts is marked for install (in synaptic opened from the livedisc) are:
This may be different with 9.10 configuration (can anybody look to see which are necessary with 9.10) I think the computer wasn't responding anymore because I used too many tabs at ones. I had this same problem a few times before in the past weeks but then I wasn't installing something and the computer did restart and firefox restored all the tabs. I cannot enter /home/ from the livedisc (no permission) and it's necessary , I am in the middle of exams and i need to print the paper that is on the disc by monday Is there a way to enter it via command console?
I was wondering if i can remote desktop with my blackberry if i could install a program on my computer that would allow me to monitor a operating system install or even use my blackberry to install the operating system.
I currently use my PC for work, music [I'm a DJ by profession], and gaming. It's got good specs and I've recently gotten a 500GB hard drive for it. I've installed Ubuntu 10.04 [using the 9.10 CD and running update-manager --devel-release]. However, in my infinite foresight, I installed Ubuntu to take up the whole drive, /home and all. I've only used about 80GB of space in /home so backing it up to start off a triple boot shouldn't be a problem.
Currently, my partitioning is /dev/sda1 at 494GB [ext3, mounted as /], /dev/sda2 is a 6.2GB extended partition, and /dev/sda5 is a 6.2GB swap partition. Basically, I need to do the following things, but don't know the least hacky way around it.
1) Repartition to make the Ubuntu's root filesystem take up ~40GB of space 2) Probably have the swap partition immediately after / (is the other extended partition even necessary?) 3) Install Windows 7 to use for gaming in a 60GB partition 4) Windows XP to use for music production in another 60GB part 5) Have the rest of the space on the hard drive formatted as NTFS & used for documents for Windows 7 (as D:), Windows XP (also as D:), and Ubuntu (used as /home/saxon).
Any pointers? I've searched around but I couldn't find anyone else with my exact problem - most people have Windows installed first and only want a dual boot. I'm fairly comfortable with the shell so I'm not too bothered about using Term either. Sorry if I've worded this awfully or seemed like a bit of an idiot
I tried Wubi, and all is fine, but when I choose Ubuntu on the boot menu, it shows some dialog, then just blank. its stays blank forever, so I had to shut the computer off.Then, I burned the Ubuntu iso to a CD and botted from it at startup. This at least showed the purpl-ish install screen. After I pressed enter over install, it went to the blank screen again. just black, nothing appeared.I'm not sure what the problem is. My laptop is fairly new, it shouldnt be having an issue to run it.I have 4Gb RAM, plenty of space on the hard drive, and a 1Gb video card...I have no clue what to do, as this is my first encounter with an Linux distro ever. help?
which log file should i look at to debug problem with system sleep or anything to do with the system won't return back after goes to sleep.
Basically i got my system running from the night before. No problem until this evening around 5pm. (i realised the problem at 5pm) my monitor goes to sleep. My system power still on. It won't respond to monitor/mouse movement. i can't ssh in.
After reboot, check /var/log/messages. The only message there before reboot was at 9am. I am pretty sure everything worked fine around 2pm.
I was running CentOS 5 with VMware Server on top of it. The system died and I'm trying to recover the VM images. The system died with a 'end_request: I/O error, dev' type message. It looks to me like the 2nd partition is wonky - is that correct? The GRUB portion does boot. I pulled the drive out and plugged it into my Ubuntu box to see if could get to the files. I ran 'fdisk -l' and found:
To me this shows the GRUB boot partition and the system drive - correct? Next I created a mount point and tried 'mount /dev/sdb2 /mnt/recover' At that point I get a
mount: unknown filesystem type 'LVM2_member'
Here's where I'm a bit lost. I believe I need to add filesystem support to my Ubuntu box. I've been looking but have yet to find something that says the default filesystem of CentOS 5 is <blah>. After I do find that info, how do I install the filesytem support to read the drive?
If, as root, I 'Leave' --> 'Logout', I get the KDE login screen.If, as user rob, I 'Leave' --> 'Logout', I get a black screen from which I must power off to recover, and I use the term very loosely. User rob is a member of the 'power' group.
