Ubuntu :: Deleted OS Partition - How To Reinstall Without Losing Information
Jan 16, 2011
My gateway netbook was dual booted with windows 7 and ubuntu netwbook.,I was attempting free up some space on my netbook and decided that the ubuntu partition was expendable.I deleted it and sufficient to say I now can't boot boot up, I just get an error message, can't remember exactly what it is.I am getting a new computer and would kind of like to be able to recover the files on the computer.I have a USB netbook boot drive and am wondering how I would be able to install ubuntu without loosing the files.I have the usb key plugged in am now at the partition stage of the installation.

I tried to install rawhide by enabling the rawhide repo and doing a yum update. Lets just say it didn't go so well. My system wont start the GUI when I start the computer. It just shows the Fedora boot animation and stays there. So anyway I need to reinstall Fedora 14. I wanted to reinstall Fedora without having to backup and restore all my data (my home directory). So I did some Googleing and found that if I had my home directory on a separate partition that I was set to go. All I had to do was format "/" and just tell it to use the "/home" partition I already had and not to format it and I that was it. So I went to try it myself and found that it was not as straight forward as it seemed. Well at least for me.
I clicked on "lv_root" assuming that was supposed to have "/" as its mount point. I clicked the edit button. I selected "/" as its mount point and told it to format it as ext4.Then I clicked on lv_home and clicked on the edit button. I made its mount point "/home" and clicked "ok".I clicked "Next" and I get this error "Bootable partitions cannot be on a logical volume". What do I need to do to fix this? I assume this has to do with the "lv_" at the beginning of the partition names.

I had to delete my swap partition in order to reinstall win XP, but now I need to reinstall it. I run Ubuntu 10.04 and read that there is a command $ sudo mkswap /dev/sda1. I have about 19 GB of free unpartitioned space left on the hardrive that I want to make into a swap partition. I'm not sure whether I should use sda1 or if the book uses it as an example and if I use it it could wipe away my existing partition with ubuntu installed on it.

How do I ensure that my home partition does not get deleted the next time I reinstall Ubuntu, as I can see there is a choice between formatting the whole drive and manually partition it, but if I reinstall won't I delete the home partition as well?

I deleted Ubuntu off of my laptop, because I was having some issues with it (I had lost some of my icons in Software Center, couldn't access my Yahoo Mail etc..). I deleted it using this method. I then went into my Windows Vista OS, and accessed Disk management via Control Panel.The partition Linux was previously on was Unallocated, and I had a D partition which was Windows recovery. I then shrunk my C (main Windows) partition down. I deleted the D partition.So now I have the C partition, and a large unallocated partition. I was planning on installing Ubuntu from CD onto this unallocated partition. I am using the same CD I had previously used to install Ubuntu. My roommate was also using the same CD today to install Ubuntu on his computer. I know the CD works.
So when I inserted the Ubuntu CD it loaded the first couple of screens. It got to the purple screen where the install text would normally have appeared and then continues to load.... but the "do you want to install? etc..." text did not come up. It then loaded to a black screen, loaded back to the purple screen, reads the disc, keeps loading... and loading... and nothing ever comes of it.I tried again, this time when the first purple screen comes up, I hit enter. I get the language select. I then get the options. I click install Ubuntu. it then starts loading... and loading... black screen, purple screen, black screen with text... but nothing comes of it.My windows is working fine. I don't know why it won't install

I've forgot to add/make clear, as I have said this is a single OS system, if there is a less complicated fix that will leave me without grub (but with a bootable system) that would be fine. Something like
Code:
fdisk /MBR
but I understand that command is only for DOS, correct?
I've managed to delete/screw up my installation of GRUB. My hardware RAID controller had gone on the fritz and I was getting an operating system not found message during boot. Turns out I needed to reload the firmware for the card. I now believe the card is working fine however in trying to troubleshoot the problem (which I initially thought might have been related to GRUB) I have managed to hose GRUB, and I now see
Code:
Loading GRUB..
Error 15 at startup. I am running Ubuntu 8.0.4 LTS. I have been using an 8.10 desktop live cd for troubleshooting. Grub-install does not work when using the live cd. I have tried to follow directions given on this page: [URL]. However if I chroot to where my OS partition is mounted on the live cd:
Code:
chroot /media/disk
it does not recognize the grub command.
If I simply try:
Code:
sudo grub
find /boot/grub/stage1
it does not find them. If I try:
Code:
sudo grub
root (hd0,0)
setup (hd0)
it checks for stage1 and does not find it. (This may be related to the fact that I am not chroot'ed to the correct OS partition when trying to run these commands, since, as I have mentioned before, I can't get the grub command to run after I chroot to my OS partition.)
When I initially started fooling around with grub I did not even have a boot partition, so I am not even sure that I had GRUB installed in the first place (this was simply a clean install of 8.0.4, not a dual boot system) but since then I must have screwed up the MBR by trying to reinstall/fix what I thought was a broken GRUB. I could not find the GRUB files on my computer, so I have downloaded GNU Grub 0.97 and unzipped it, and moved the entire contents into a /boot folder which I created, so I now have the proper /boot/grub/stage1 directory. (However I never ran any installation after downloading grub, I simply moved the files, perhaps this is the issue).

I tried this once but my post disappeared. A thousand pardons if this is a dupe.Through the magic of typos, I managed to delete my ssh binary file. I can receive SSH connections but am unable to SSH into another computer.I located the RPM that looks to be what I'd want -- openssh-4.3p2-41.el5_5.1.i386.rpm -- but it refuses to install. RPM gives me the following conflicting messages:
[root@lightning packages]# rpm -i openssh-4.3p2-41.el5_5.1.i386.rpm
package openssh-4.3p2-41.el5_5.1.i386 is already installed

I was having a problem where I had run keytool to generate a key but had entered some bad info. I tried to run it again but it said there was already a key, so I deleted keystore thinking it would regenerate itself. I ran the keytool command again but it says it can't derive the signature algorithm.
Anyway, I've tried to 'sudo apt-get remove sun-java6-jdk' then 'sudo apt-get install sun-java6-jdk' but it doesn't seem to put me back where I was from step 1. 'sudo dpkg-reconfigure' also doesn't seem to fix it. I think if I can completely reinstall jdk then I'll be good, but how?
I just uninstalled, did 'sudo apt-get clean sun-java6-jdk' then installed again. Still get the error:
keytool error: java.lang.Excpetion: Cannot derive signature algorithm

I got a system crippling virus on my windows installation. My recovery disks gave me the same problem. So I installed Win 7 enterprise using a disk my dad got from his work. The installation went smoothly. When I started my computer after it went straight to Win 7 without the GRUB bootloader (not the case with restore disks). Could somebody please help me with this issue because I cant stand using Windows for anything other than games much longer.

Currently, my partitions are set up as such:
83GB ext3 free space
~10GB ntfs HP/Vista Recovery Partition
~93GB Ubuntu (Hardy Heron)
I tried to just have two partitions (recovery and ubuntu), but because of the different file systems, and the placement of the hp recovery partition, it has to be right in the middle. This is basically what I want to do:
1) Reinstall Hardy Heron on a new (smaller) partition from the free space partition.
2) Once it's working properly, format the rest of the hard drive (getting rid of the recovery partition) and create a single ext3 partition.
3) Install another distro on this new partition.
Does anyone foresee any complications with all this slicing and dicing of my hard drive for which I should/could prepare?

This is my first post on Ubuntu, ive been testing/and dual booted then reverted back to windows this past year, and now have gone back to school for computer networking...so im SUPER interested,So - i want to install Ubuntu on my little Toshiba netbook that i drag everywhere with me, but im afraid to screw with it's partitions. I dont want to spend $$$ to get a larger than 8GB flash drive to create a recovery from the HDD partition that is installed on their, and they dont come with the backup/recovery disks, so i want to either leave that partition alone (in case i need to switch it back to windows down the road to sell it), or whatever.
I know i could just download windows to my PC, transfer the files to a flash drive, and put it on that way, but the recovery comes complete with drivers, etc which makes it a smoother and faster process. Oh, i cant make the recovery of windows b/c i need 7.xx GB of space, and my biggest flash drive is an 8GB which doesnt quite make it.SOOOOO - IF i install Ubuntu, will that recovery partition DEFINITELY be left alone? Or is there an easy way someone could suggest copying that partition without a 16GB drive? OR is there any way to use an external hard drive to copy that recovery partition on to?
I have only installed ubuntu once, maybe twice, but didnt care about partitions and wiped everything as requested by the install. (i reverted back because i couldnt navigate quickly installing and updating programs, but now have a windows laptop and want to be forced to learn linux on my netbook).any help is MUCH appreciated! I have an Ubuntu scratch that im dying to itch, but dont want to lose my windows recovery

I want to wipe out my Windows partition and reinstall due to sluggishness. I plan to use Windows instructions as if it was on a hard drive by itself. Will this affect the multi-boot capability or the Linux partition in any way? Would it be easier to reformat and partition the entire hard drive and re-install both OSes? I use OpenSuse 11.2 and Windows XP.

I would like to resize my /home ( /dev/sdb6 ) partition - without losing data - to make room to create a swap partition (at the moment, I don't have any swap. Is it dangerous ?) IIRC, it was possible to change partition sizes from the install disk in repair mode (?) But I cannot find that repair mode on the 11.3 install disk. Has it been removed or is it somewhere deeper in the install or update process ?

I got a new laptop today (yay) with windows 7 on it. I want to keep a small windows partition, just in case I need it for something. Anyway, I know how to use fdisk, and am comfortable installing on a disk without data I need to maintain.. but this new computer came with 5 (!) windows partitions. I don't know where to start.
I don't mind reinstalling windows after partitioning if I have to, but I really don't want to screw up the recovery partition. Any clues on where to start or what to look for? Or what NOT to do?
It looks like "my computer" has two partitions listed (c: and d: ). I guess I could just take note of the size of these two partitions, free up the partitions that match in fdisk, then repartition that space and install everything.
I need to reboot to do that, so I'll edit with the information when I have it.
fdisk output:
Code:
Disk /dev/sda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x8e0eee9e
