Ubuntu Installation :: Delete Grub From Boot Sector In HD Of Toshiba Notebook
Jun 7, 2010
I have a toshiba notebook with Windows XP and Ubuntu studio. I removed Ubuntu partitions with the idea to install classic Ubuntu, but... grub don't recognize Windows to boot. I formatted the hard disk as slave from another PC. I installed Windows again trying to delete the grub, but, it is already there. I am trying to repair grub from Windows with: FIXBOOT, FIXMBR, fdisk /mbr from MS DOS, but that is not working.
Any suggestions:
- To delete the hard disk complete and start again everything. (deleting grub also)
or
- To repair boot sector for Windows
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 a complete noob at this and I need a hand. I was about to throw my computer out of the window when I decided to throw the windows out of the computer so to speak. So, I downloaded Ubuntu 10.10 and tried to install. I had a grub rescue after the installation (file system unknown), which I have seen discussed here. Being the noob that I am I decided to try 10.04 because it said it had full support. With this install I get a similar error during installation: grub cannot be installed in boot sector.
So, basically there is an issue with grub and the boot sector. I checked in my BIOS options to see if there was an option that prevented the writing of a boot sector or something, but I have not been able something like that. So, I am wondering if it is possible that Ubuntu does not really erase/format the selected disks or something, leaving any difficulty there.
Does anybody know? Or better yet: what exactly do I need to do a manual grub install?
The boot sector somehow got messed up on a friends computer while updating. I used to know how to do it with the old version, but now that they've updated it and changed everything , how do you repair the boot sector from a live-CD with Grub 2?
The project was an update of a cluttered dual boot ubuntu/XP laptop to ubuntu 10.10. For work, I sometimes need Windows, regrettably some software needs Explorer or indeed W$ itself to operate.Grub 2 still seems buggy, install was fixed by
Code: sudo mount /dev/sda6 /mnt sudo grub-install --root-directory=/mnt/ /dev/sda
The computer will constantly be running in my cupboard 24/7. Using it for movies, videos and pictures. Just a home file server so I can I backup all my digital items. What version of Ubuntu should I be using? Server or Desktop? Right now I'm using Windows XP Professional at the moment but I'd rather use Ubuntu personally.
I've spent the past 2 days attempting to get the sound working on a Toshiba A75 notebook. Here is what i've tried so far: remove/purge alsa and pulse audio then reinstall set up/configure OSS download and compile latest alsa drivers. code...
My questions are: is there anyone using this laptop on Lucid with sound? Can anyone provide a new idea how to make this work if it is compatible hardware.
I currently have XP installed on a NetBook (Samsung NC10), and would like to run Fedora on it. I'm currently looking at putting Fedora onto a flash memory card to test it works OK on the hardware, before installing it to the hard disk. The problem I've got is that the boot sector is occupied by WDE software (TrueCrypt). Will this pose a problem for dual-booting XP with Fedora, or will GRUB move the boot loader in the usual way?
I have a rather puzzling error. I recently purchased an usb external hard drive with the intent of installing Ubuntu on it. I have had great success with installing various linux flavors on usb thumb drives but I need a little larger space for engineering applications that I use. Anyway, I removed my laptop's internal hard drive and installed ubuntu 9.10 on a recently formated external hard drive. Everything worked fine at first. Upon restarting I get an error that says "no boot sector" and it asks to hit either f1 to retry. When I hit retry, Grub loads most of the time. Occasionally it does not work. Is Grub just not installing correctly? I searched for this error but I found nothing that directly applied.
My old Dell Inspiron 9300's CD Rom is no longer working. I've written the files to my 8GB USB device, and attempted to boot from it. Whenever I try, I get this "No boot sector on USB device". I'm also using Mac OS X to make the USB drive.
3 partitions (in order): Windows 7, CentOS and shared data partition.
I need to increase the size of the Windows 7 partition (c:windowswinsxs seems to be something not easily remedied).
GParted didn't work in moving things around (bad sector) so I wiped out its partition (# 2 out of 3) and I was able to increase the size of the Windows 7 partition (I can reinstall CentOS easily and not much work lost).
Except ... no more grub menu (unsurprising). This incantation does allow me to boot into Windows 7.
Is there any way of rebuilding the grub menu short of reinstalling CentOS (5.5)?
I just installed squeeze from a usb key. Installation went flawlessly but now I need the usb key to boot. Nothing happens if I let the bios boot from the HD or if I force it to do so. When it boot up from the usb key, the HD is read and the boot up sequence continues. Grub seems to be installed in /boot/grub. I imagine that I have to copy the usb key boot sector to the HD but how?
Been away from linux for a few years thaught id come back and give it a try again. I have Win7 on sda and installed 11.4 Ubuntu on sdb. Grub2 Over wrote the boot sector for windows so windows wouldnt show in the boot menu. I repaired that after some research and then tried it again with 10.4 LTS version of Ubuntu. Same thing. Now I've fixed windows boot sector a second time and im ready for round 3. Any hints on how to get grub2 to boot both OS's? Ubuntu 10.4 is still on sdb I think I should just need to re-install grub2 But how to do it without Killing the windows boot sector?
I have a busted XP notebook, no CD, no boot from USB. I have the option of booting from network, my provider wants to charge me to set up a static IP address I'm hoping to just plug in to my working 8.04 install with a cat5 cable or through a simple workgroup switch & get the basics installed where would I find such a procedure?
the gateway notbook hangs, part way through the restore [xp] process, I can only get to bios & restore, no dos prompt I don't care about any of the info or having XP I know the HDD may be bad
I installed Fedora 15 on a primary partition and expected the install to create a partition boot sector, but it didn't. Did I do something wrong or is this not supported?
I have removed Ubuntu and I just have Windows 7 installed.
When I turn on the laptop, Grub tries to load but it fails. I have used Windows 7 install DVD and clicked into repair windows start so I should get Windows default bootloader back, but when I restart, Grub is still there...
How do I remove grub and get the laptop to boot into Windows automatically?
This is my HDD, btw: [URL]
Note: I'm booting right now using iBoot, how do I repair this problem? I may run chkdsk, Windows asks me to run it every time I boot into it since 1 or 2 weeks... maybe it won't repair the boot loader until I ran chkdsk, I dunno
installing Ubuntu 10.04 on my notebook. Currently, I am using IBM Thinkpad X31 with docking that has swappable 2nd HD. The 1st internal HD has WIN XP on it. I had successfully installed Ubuntu 10.04 on the 2nd HD and everything work properly with GRUB menu asking which OS to boot when start the computer. However, when I have to swap 2nd HD out with DVD-Drive or undock, it won't allow me to boot into Windows XP -> showing device is not found and prompt to "Grub Rescue" command. It will only boot if I retain 2nd HD in the dock. So I will like to know how to make Window XP boot without 2nd HD, and still able to get in Ubuntu when I insert 2nd HD into the dock?
No I have been on the road for some months and felt the need to buy a small notebook. I assumed it would be possible to put on ubuntu, to go back to this amazing system.It is a strange Peruvian brand and I can not seem to get ubuntu installed I feel so naive of thinking it would work. details>

I had ubuntu studio installed ( for the record I hated it and every ubuntu flavor I have ever used. ) After backing off all the stuff from my home dir I started to install testing from a dvd. ( Is there a net install for testing? I couldn't find it) Don't ask me how it happened but some times I would have two grub graphical boot menus. One would chain to the other. I suspect that happened from one of the very friendly updates ubuntu did. Well when I tried to install testing I got a red screen telling me that grub wouldn't install so I tried lilo. Well it wouldn't install either. Back in the old days when I was a slackware guy installing from a stack of floppies I had a trick to wipe out any boot loaders or other stuff that gave me a problem. I would dd if=/dev/zero of=/dev/<drive info such as hda with no partition number> .
This would write zeros over the drive and it would look like a new drive. So I did this trick. But still no joy ( this is a clue, dd was also thinking that the beginning of the drive was after the boot sector.). I suspected that the installer wasn't doing it's job right. So I got a PCLinuxOs disk and started that installer. The PCLinuOS installer has a cutesy visual bar that shows the partitions. Well sure enough the boot sector showed as blank. This was what the Debian installer had done. It left the boot sector blank and tried to install the boot loader right after it. This won't work. Now I consider when some version of Linux falls on it's face and another version does it right that the version that fell on it's face has a problem.
One might even call it a bug. But I don't know what to do about it. I don't think the problem is with grub or the installer itself. I think how the drive was looked at was faulty. That's why dd didn't blankout the boot sector. So what do I do to help get the Deb people to fix this? The more I think about it the more I think the problem is with udev ( what a surprise) I think this because I suspect dd looks to the info set out by udev to find the beginning of the drive.
I tried to help my friend install Ubuntu 10.04 side-by-side with Windows XP on his Acer Aspire One netbook.Unfortunately, the installation process came to a standstill and it quit due to "unexpected errors". The second time I started the installation, I realized that the option for installing side by side was gone and that I could not mount the C: partition on Ubuntu. The error message is listed below:====================BEGIN ERROR MESSAGE======================Error mounting: mount exited with exit code 12: Failed to read last sector (299982847): Invalid argument
HINTS: Either the volume is a RAID/LDM but it wasn't setup yet, or it was not setup correctly (e.g. by not using mdadm --build ...), or a wrong device is tried to be mounted,

I was dual-booting Vista Business and Fedora 12 on the same hard drive. I deleted the Fedora partition and expanded the Vista partition to use this space.
I figured that because GRUB was on the Fedora partition (at least, I thought it was), I'd just be able to load up Vista as usual.
When I turn the computer on, a GRUB command-line comes up, and to be completely honest, I have absolutely no idea what to do at this point. I'd quite like to just get rid of GRUB entirely and boot straight into Vista, but again, I don't know how.
I've tried using a Vista recovery disc to sort out startup problems, but it doesn't do anything because the problem occurs before control is passed over to Vista.
What can I do to fix this problem? Can I get delete GRUB and boot straight into Vista? How?
i want to boot windows from grub loader and delete linux .Is this possible?or can i keep only /boot partition so that windows boot from grub prompt i want to boot windows from grub loader and dont want any linux partitions on my machine.Is this possible?or can i keep only /boot partition so that windows boot from grub prompt and delete rest of the linux so that i can get all free space.it is not possible for my system to get windows boot loader hence i want only grub boot loader to load only windows.
how to change (rename, delete) lines from boot list in grub 2, Ubuntu 10.04? For example, when I boot my pc, I have a boot list with options "Ubuntu 10.04", "memtest" and "Windows 7". I want to delete "memtest" line, as I don't need it, and rename "Windows 7" line to, for example, "Windows 117". How can I do that? Where I should look and edit? In old grub it was enough to edit /boot/grub/menu.lst, but in Ubuntu 10.04 there is no such file and other grub2-related files (like grub.cfg) do not contain this info to rename or delete lines. So, I can't figure out what to do.
I just bought a new computer, a Toshiba satellite a505-s6005 with an i3 processor and 4 GB of RAM [URL]. I wanted to install Ubuntu 10.04 (32-bit version) on it, but it was giving me a black screen with some writing on it every time I tried to boot it from the CD. I did manage to finally activate the installation process, by choosing the acpi=off function on the installation menu. I was going fine until I at the very end I got some I/O error and when it rebooted, it gave me the same black screen with writing on it. It does this every time I try to go into Ubuntu.
I just used Update Manager to upgrade to 10.4 and all I get is the Ubuntu logo screen with the dots and then the screen goes black and there's no other response. This happened after the upgrade completed installing and I received the message to restart the computer. I have never been able to get it to boot.
I can boot fine by selecting the next older kernal although I do get some messages that I don't understand. It all works so I presume it's OK. The kernal that was installed with the upgrade is 2.6.32-24-generic and I've seen other posts about boot problems with it. The laptop is dual boot with Windows XP and Windows boots normally. I saw a suggestion on another thread about booting into an older kernal and then issuing the sudo update-intramfs -u -k command. I tried it and it didn't help.
Next I tried 2.6.32-24-generic recovery mode and I tried the option to fix damaged packages. It seemed to do something although I saw error messages about not being able to find various software sources. I tried a normal boot afterwards and same problem. Recovery mode has another menu option about repairing grub but I don't want to try that. I'm not a power user and this is all over my head. Before I turn the laptop into an unusable door stop,
I have an issue with my keyboard not being picked up in Ubuntu and I went to go ahead and boot into the factory recovery partition to start from scratch, but after it gives me a ramdisk loading bar, then goes to a black screen with a mouse like the recovery will start, then the computer just restarts. Now, I can boot into Ubuntu (but no keyboard) and boot into XP (as I am now) but I can't get the recovery partition to boot.My current station is out in timbuctu, so I am awaiting the arrival of a flash drive to load a LiveCD onto to use Gparted for any potential solutions.
