Ubuntu :: Boot Partition Missing & USB Not Working
Jun 14, 2010
Apparently I altered my partitions while trying to make room for Ubuntu 10.04, and now I'm in a mess. For two weeks I have been searching the forums for a solution only to find instructions I don't understand or partial solutions.
Here's my situation.
I have an Acer AspireOne netbook (no CD, only USB).
I am able to access F2 setup, so I can prioritize the boot order. I can position my bootable (ubuntu-10.04-netbook-i386.iso) usb drive at the top of list, but when my computer reboots via usb, there's just a black screen with a white dash in the upper left corner that flashes.
When I boot with the hard drive I get:
So far, the only commands I have found that work are:
Now, like I said, I'm a newbie. But that hd0,5 concerns me; doesn't seem to fit.
I'm not concerned with saving data. I'm willing to start from scratch. I just can't get past that grub rescue prompt and I can't access my usb port so that I'm able to run the LiveCD.
I had a dual boot system(WinXP and Ubuntu). But something happened and I was not able to boot into my Ubuntu partition. It gave GRUB missing error. I tried reformatting the dedicated 40 GB ubuntu partition to NTFS and again try to reinstall ubuntu. But now, when I install ubuntu through boot time install, it shows that my whole hard disk is empty( but I have windows XP on whole hdd at the moment) and do not give any other option but to use whole hdd.
Alternatively when I try to install it inside windows, then after rebooting it shows, no root file system defined error and neither gives any option to do so also ( this method worked earlier o my PC). At the moment, It still shows ubuntu and windowsXP at OS choice menu at boot time but when booting in ubuntu, it shows GRUB missing. (I don't have any ubuntu installation on my hard disk at the moment).
I have been foolish and accidentally deleted the 'Boot' folder from my Vista partition and now cannot boot Windows from the GRUB launcher. I'm not sure what to do next, since I can't find the recovery DVD either.
I managed to find a site with the 'bootmgr' file available to download but couldn't find anywhere to download the contents of the 'Boot' folder. Can anyone point me in the right direction? Is there any software that can be run in Ubuntu (which launches perfectly well of course) which might fix this?
Im running ubuntu 10.10 on a dual boot machine together with vista. When I tried to delete a partition in gparted I accidentaly deleted the general partition table so I had to run testdisk on a live cd to restore it. The problem is that once I had done that and rebooted I get the message bootmgr is missing. I suppose Testdisk deleted or overwrote mz grubloader.
I've just (finally!) gotten around to upgrading a couple of machines at a company I do some work for. One machine had a problem when I rebooted onto the new system. During the boot sequence, when it was checking and mounting the filesystems, it was unable to find the /boot partition. Now, this machine does run LVM on all but the /boot partition. The two SATA drives are mirrored, and they have the same partition layout:
Disk /dev/sda: 320.0 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes
[code]....
I got the system to boot by commenting out the /boot partition in /etc/fstab, but this is certainly only a temporary solution. The other system that I upgraded came up just fine, as have several of my own. Unfortunately, I am doing these two systems by remote control via ssh as I have only limited plysical access to them. (I did have to get to it to figure out why it didn't boot up..)
I am trying to install a box here where my /storage partition is about 2.5T.I had setup the partitioning with suse, while testing, and all worked well.Now when trying to install CentOs 5.5 it gives me an error, that my boot partition is on a gpt partition and this machine cannot boot that.Also I don't see the option to create XFS partitions from the installer.Can 5.5 support GPT @ install time?
i am having a problem with my dual boot setup. I originally installed windows XP on a 100gb hard drive, from there i downloaded and burnt ubuntu off so i could install it on my 200gb hard drive. For a little bit i struggled to even get it to install because it wouldn't recognize my onboard nvidia graphics, i ended up having to get an alt boot disk and fix it with technique in this link:

Now after the bios boot, my screen shuts off for awhile and takes me directly to the login screen for ubuntu. No Grub, no windows boot options, nothing. I tried booting windows by choosing it from the bios boot menu but all it does is hang at prompt and doesn't boot at all. I tried the live cd fix and reinstalled grub but nothing changed. What i think is happening is that it boots the Grub menu but it doesn't display it because of graphical confrontations. It hangs for about 10 seconds, the grub default time, and then turns my monitor back on to display the Ubuntu login screen.
I have a dual boot machine, and I made the windows partition 13 GB on a 120 GB hard drive.I was testing out a program on the windows partition, and I deleted it and installed a different version, now I'm trying to install the first version I was using. The problem is that its now telling me there's not enough space on the hard drive.why does the program not remove everything when I try to uninstall?if I install a program and then remove it , I should and up with the same amount of free hard drive space shouldn't I?
using onboard windows disk management i have made 75gb unallocated to add to the aforementioned ntfs data partition. but, after resizing extended partition, will i need to fix grub even though i will be adding the unallocated space to a storage partition and not the ubuntu boot partition?
I am keen to start using Ubuntu and have installed it on one of 4 partitions on my new 1 TB external HD. I got to the reboot stage where I was expecting a new boot screen where I could decide to use either XP or Ubuntu. But there is no mention of Ubuntu just XP and the volume I installed Ubuntu on has disappeared. I can find the other 3 volumes on My Computer.
is it possible to use a Windows-based recovery partition on a dual-boot computer to overwrite the Ubuntu partition and remove the GRUB loader? For instance, if you booted up your computer, accessed the hidden recovery partition and used it to reset the computer to it's factory default settings, would that effectively remove the Ubuntu partition and the GRUB loader? Would a completely new installation of Windows overwrite/uninstall Ubuntu and GRUB automatically?
When I installed Ubuntu on my system (a year or so ago) I forgot to add a BIOS Boot Partition. This is something of a problem considering that the partition type for my 2TB drive is GPT. Hence, whenever grub is updated I get a warning:
Code: /usr/sbin/grub-setup: warn: This GPT partition label has no BIOS Boot Partition; embedding won't be possible!. /usr/sbin/grub-setup: warn: Embedding is not possible. GRUB can only be installed in this setup by using blocklists. However, blocklists are UNRELIABLE and its use is discouraged.. Installation finished. No error reported.

If so, what is the rough sequence of commands to create the partition (without disturbing what is already there) and then setting it as a BIOS boot partition.
I installed Ubuntu as shown in the wiki and when I went to restart it gave me a lovely blinking cursor and nothing else. So I held down option, loaded into osx, reinstalled rEFIt and got my menu on startup. Unfortunately, the partition sync tool doesn't seam to be working, it gives me an error: Status: MBR partition table is invalid, partitions overlap. Error: Not Found returned from gptsync.efi
Everything is installed and setup on my system, but when I setup my partitions I chose my Windows partition to be bootable. Can I just use cfdisk to toggle the bootable flag so my linux partition is bootable and rewrite the partition table?
I having a problem getting my grub loader to see one of my hard drives. I added a drive, and my grub loader lost track of where everything was. I couldn't get my old linux (Red Hat 9) so I installed SuSe on my new hard drive. But I need my be able to boot from my old hard drive because it has apps that only run on the earlier version. From /proc/partitions the old hard drive is sdd
major minor #blocks name 8 0 976762584 sda 8 1 2104483 sda1 8 2 20972857 sda2
when I tried to install Fedora on my pc, I got this error message " Defined Root partition not created a / boot/efi partition. I am trying to install it on a seperate hd. My main one has windows xp pro, but I do not want to interfer with that at all?.
I have a system running OpenSUSE 11.3 using the bare server configuration.I had a partition for my /srv directory. All was fine until earlier today. I shutdown my system (to remove an old floppy drive from it). When I rebooted, /srv is emtpy (no files nor directories). This is somewhat vexing, as I had several sites running from there, as well as a fair amount of data.The appropriate partition (/dev/sda3) appears using fdisk. However, there is no mention of it in /var/log/messages.Does anyone know how to recover an Ext4 partition?
I want to install more than 3 linux distributions on single disk - my test machine.Is it possible to create boot partition on logical partition whitch resides in extended partition (and boot successfuly of course)? My boot loader lives elswere (primary partition or MBR).
I used to have a 1TB external drive with lots of stuff on it. But after a reported drive failure during a F11 install the partition table seems to have been lost. (I think F11 toasted it)
Disk /dev/sdc: 1000.2 GB, 1000215724032 bytes 255 heads, 63 sectors/track, 121602 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes

The drive used to have xfs and a partition. Is there any way to rebuild the partition? Or is my 1TB of data gone forever? The drives seem to be fine now... I just want to get it up enough to either pull any data or just to get a file list. Most of the stuff on the drive was from somewhere else.(ie 300GB of NRN data for all of North America.
I'm trying to set up a Ubuntu box as an NFS server. I've set up /etc/exports, /etc/hosts.allow. I've installed nfs-common. I've got everything as far as I know installed but yet, when I run rpcinfo -p, I do not see mountd. Everything else seems normal.On the client machine, when I try to mount I get a Program not registered error.
As a matter of fact, when I do a 'find' for *mountd* in /usr and /etc I don't see anything. The literature says rpc.mountd should be a part of nfs-utils, but of course Ubuntu lacks a package by that name and nfs-common does not seem to have it.
I have just updated my 7.10 release to the final release patches/kernel for it (as a step in the process of upgrading the installation to 10.10) when I have come across a very disheartening problem.
Prior to this update, I was running VMWare Server 2.0 with its normaal admin console at localhost:8333 and an applet install under Applications -> System Tools -> VMWare Administration Console. Now that I have updated, both these are missing or inoperable.
However, the VMs hosted by the machine are still perfectly functional. I can login to the via Remote Desktop or VNC as the case may be.
I can also no longer see the /var/lib/vmware/Virtual Machines folder or any VMWare folder at all, even when using the full root login and permissions. Find and Search also show a disturbing lack of the 64Gb of VMDK files that are the running VMs.
Any clues as to how I can track down this invisible, but functional install? I do not want to proceed with another update until I get a solid backup of the VMDKs.
I'm running 9.10 off of a 4 GiB CF card. I keep running into space issues with updates, so I purchased an 8 GiB replacement card. I've cloned the 4 GiB card to a .IMG file using DD.I've then copied the 4 GiB image back to the 8 GiB card using the Ubuntu startup disk creator program. Once done, I'm able to properly boot off of the new 8 GiB clone.Unfortunately, the clone ends up with 3.67 GiB of unallocated space at the end *see attached). I tried deleting the "extended" partition that the swap is located at after booting from a Live CD and the system was unable to boot after this. I was thinking that I would delete the swap entirely and create a swap file after I merged the existing partitions, but I was unable to do this.
best way to do this (e.g. get one large 8 GiB partition with my old image on it)? I still have the original untouched 4 GiB card and also have an external CF drive if I need to redo the cloning. I've also used Clonezilla before, so perhaps there's a way to do this that allow me to grow the image as it's being cloned.
I am building a 10.04.1LTS server. I am putting the /root filesystem into a Software RAID1 partition. I want to keeo my /boot partition outside of RAID.Is there a way to have a boot partition on both sda and sdb so if one drive fails the second boot partition will work away - or should this be kept in with RAID also.
I am using a hp pavilion zd7000, computer says firmware is missing for wireless controller. i also have a wirless g notebook card made by belkin which will scan for networks but wont connect to them for some unknown reason. if i can get either the wireless g card to work or the built in wireless to work thata be great. I am well experienced in windows but very new to linux and how everything works.
My laptop can't boot from cdrom becouse it is broken and it can't boot from USB becouse it has never been able. Ubuntu 8.10 now run in my laptop withgrub 1.I've just try the following trick.1) I put grub4dos in /boot2) I put iso image in /boot3) I add the follwing entrt in source.list
Code: # =========== GRUB4GOS =================================== title == Use grub4dos for the following entries: ==
Added an SSD (dev/sdc) and decided to move some less often changed directories there. Started with /usr and /boot, leaving / on a primary in the first drive, for now. All started ok, and my changed fstab mounted the right ones, and the system works.
However, grub is actually using the original /boot on / on sda1. I cannot see any way to change this. (Which makes it sorta hard to update the kernel
From grub:
Okay, since it has two choices, I tried to tell it which one to use. But, grub> root (hd2,5) does nothing.
Disk /dev/sda:
what I seem to recall, grub doesn't care about the boot flag on the disk. Nor does it care about primary vs. logical (except GNU doc says "makeactive" only works on a primary?).
The GNU doc also indicates that it looks for a directory /boot on the partition, so if you're mounting a partition as /boot, it also needs to contain a /boot directory under it. Tried that, but no change.
Is my problem the logical partition? Does that prevent "grub> root" from changing it? I'm afraid to wipe out the old /boot and find that I can't start up.
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:-
[Code]....
Following the Grub2 tutorials I have tried editing /etc/grub.d/40_custom as follows:-
[Code]....
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
