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 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?
View 5 Replies View RelatedI 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?
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've been running a dual-boot ubuntu 11.04 64-bit and windows 7 64-bit for a while now, and recently got a new computer. I moved the hard drives to the new computer (one had both os's on it, the other was just a storage drive) and windows 7 would not boot, so I reinstalled it. I used a live cd to repair grub using boot repair /Boot-Repair) and everything looked to be going swell But when I tried to boot I got "invalid or damaged bootable partition" instead of a grub menu. so I went back and, copying and pasting the commands the program gave me, I manually removed and reinstalled grub on my ubuntu partition. same error. so, I backed up all my documents onto a third drive, wiped everything out, and started again. I installed win7 on one drive, and then when that was done, I installed ubuntu on the other. lo and behold when I tried to boot I got the same error message, and now I can't even boot from my windows drive. The ubuntu drive is fairly new and according to disk utility has no errors. Is this some problem with grub or what?

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?
View 2 Replies View RelatedI'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.

Caused by Used fdisk to delete the windows partition, in my dual boot. Then I could no longer log in to ubuntu, the partition table was some how courpt and I couldnt remount I then decided to use the windows partitioner from windows setup, as I thought it is so stupid, to reformat the partition where I had ubuntu. I wanted reinstall ubuntu, and I know that during the setup I could straighten out the mess I'd made.
Windows has now installed two 8mb one cylinder partitions on my HD. When I start the PC I get a !disk error occurred Press Crlt Alt Del to restart! This happens everytime. HD boot sequence is buggered, i guess.
I can boot from other devices. USB + CD. How when I use the windows disk to boot up I can see the 2 8mb partition, which it wont let me delete. How can I delete this via linux?
Also when I try to install ubuntu from the usb drive, it stalls just after the Preparing to install part. The next screen is when you set the partition table, swap drive etc. When I quit I get the following error !Process Glib WARNING getpuuid_r() failed due to unknown id!
The usb_liveCD does however mount my hard disk partitions and luckily I have managed to back everything up to an external.

Whenever I boot my laptop, I get the following three lines:Code:error: syntax error.error:Incorrect command.error: syntax error.Right after I see the error messages for a couple seconds, the boot screen shows up and the rest of the boot progresses as normal. I'm on a Wubi 10.10 ubuntu install and I'm pretty sure this error has something to do with the GRUB_TIMEOUT line on 'etc/default/grub' file.I was experiencing some weird glitches with the boot splash screen (it was in the wrong resolution and would not display some times) so I edited that file to make it work. Here is the file:
Code:
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.

I am having weird problem with Grub Menu listing during Grub display at Boot. I Multiboot with Lucid Lynx, openSUSE and Windows7. My Grub is installed along with Ubuntu. I did not install bootloader when installing openSUSE.
Now during boot Grub Menu displays five entries for openSUSE. However when I did grub-update in the terminal it shows only one image for openSUSE in terminal.
Quote:
But again Grub Customizer shows or lists five entries for openSUSE. (Please see the attached screenshot)
There are no problems during boot (except that Ubuntu takes a bit longer to load). I am really annoyed by the multiple SUSE entries in the GRUB and also by the fact that Ubuntu takes a bit longer than normal to boot.
I'm using 11.04 and when I boot I see post messages and then when it gets to grub I just see black screen with a monitor timing not supported issue. I have a geforce 6100 nforce 405 video card with a Dell U2311H monitor. It does boot to the desktop eventually, and everything from there on works as expected.
View 4 Replies View RelatedIts basically an old SATA Hard Drive with a Windows XP partition I was trying to sell.When my computer does the BIOS checks, it doesn't pass the SMART test (but I can boot it anyway), although I can't boot Linux in any way with this Hard Disk connected (I even tried Live CD distros, like Parted Magic).I can boot the XP partition from inside the disk, although I guess its pretty close to not being able to.

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.

View 3 Replies View RelatedI 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.

I have been running a dual boot system with Windows XP and Ubuntu 10.10 64 bit with the dual boot selected by Grub (placed y an Ubuntu install).
Recently I have installed Window 7 Home on a spare disc. My Bios allows me to select which disc to boot.
The Win7 installation has overwritten the boot sector on the WinXP/Ubuntu dic so that it is now not bootable.
I can sse all my Ubuntu files with a Live Linux Disc, so I can get all my files back.
Is there any easy way to re-install Grub or should I just do a clean install of Ubuntu, perhaps to a blank partition?

View 8 Replies View RelatedI'm writing a C program that reads the boot sector of a USB disk. (it is mounted as /dev/sda1). I'm able to read the sector, by the calls code...
The problem is when I wish to write. I use the call:
bytesWrite = write(fd, buf, 512)
The 'write' returns the value of 512, which looks as if the write was successful, yet
when I read again the /dev/sda1 device, I see that no writing was actually made.
Can anybody tell me what do I need to do in order to allow an actual write to the

View 13 Replies View RelatedI run 64 bit ubuntu 9.10. I recently rebooted my computer with a flash drive plugged into a USB port. My question is, could I have got a boot sector virus because of this? What are the symptoms of a boot sector infection? After the incident, I scanned the flash drive with clamav and it didn't detect any viruses. Also, in the BIOS, the hard drive is higher up in the boot sequence than USB mass storage drives. These two things suggest to me that a boot sector virus is improbable. But, recently, when I tried to boot into ubuntu, I got an error message saying that /dev/disk/uuid<some characters here> didn't exist.
Is this a symptom of a boot sector virus? So, I ended up re-installing ubuntu and I believe grub was written to the MBR. Will this have erased any boot sector viruses that were on my system? Can a boot-sector virus affect linux too? How can I check to see if I have a boot-sector infection? I also have windows xp on my computer. For some reason, windows xp isn't letting me install any updates, but this has been going on for since before the above incident with the flash drive and therefore I don't think that is due to a boot sector virus.
I was using the disk utility on Ubuntu 10.04 and wanted to make by 500GB external NTFS formatted USB drive into 1 x 50GB FAT32 and 1 x 450GB NTFS. I clicked the option that said format or create a partition and it basically wiped the whole thing in a split second leaving me with 500GB of seemingly empty space. Obviously the files are still there but I cannot boot the drive to view anything. I have downloaded testdisk, but don't know how to use it, but I am sure there is a relatively simple solution here. I am currently repairing the boot sector of the drive as Test Disk showed the drive as "no type" i.e. not FAT/NTFS/ext4 etc., but shows the correct amount of used space though, but I cannot view anything err go, I cannot use the undelete command as yet.

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?

View 3 Replies View RelatedI 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.
