I had linux when i bought my hp compaq presario laptop.Then I installed windows 7 on it.I had my windows for3 years and didn,t had a problem till now.I updated windows and then when it restarted the grub...


Sounds like you may have installed windows alongside of linux after linux had been installed. This is not usually advised. If this is the case your most likely seeing windows boot loader instead of grub. If you did in fact fully replace with windows then the update may have two installations of windows on it. Either way I would recommend backing up data on hard drive (use a live cd to view data) and format hard drive and re-install Windows and if you had/want linux as well, install that after windows. If you can give me a little more info I can help you more.

When a Windows install kills your dual boot to Linux


Distro installers are pretty good at identifying an existing Windows installation and setting up dual booting, but should you have to reinstall a spyware-riddled Windows install you'll find that your machine boots straight into Windows and that your Linux installation is gone!
Don't panic: all Windows has done is overwrite the Grub bootloader with its own equivalent, removing your boot menu. All your data is still there - you just need to reload the bootloader configuration into the disk's master boot record (MBR). You'll need to boot from a Live CD to do this, this, then open a terminal and run

sudo grub-install /dev/sda

This assumes you have everything installed on the first (or only) hard drive. Grub-install will usually make a good job of detecting a Grub installation and set things back to rights. If it doesn't, you'll have to do it manually, which is a lot easier than it sounds. Run sudo grub to enter the Grub shell. then run

find /boot/grub/stage1

...to determine which partition holds the Grub files. If Windows is on the first partition Grub is likely to be on the second, in which case this command will return something like (hd0,1). Now set Grub up with

root (hd0,1)
setup (hd0)
quit

The first command identifies the boot partition, the second writes the bootloader to the MBR and then you leave the Grub shell. Grub is only concerned with the location of /boot, so if you have a separate /boot partition, omit the /boot part from the find command.

How to remove Ubuntu from a Vista dual-boot config

On my new PC I wanted (still want) to have toa go with Linux. I chose to experiment with Ubuntu. I downloaded thedesktop CD, burned it, freed up some disk space (inside Vista) andloaded up Ubuntu from the CD. After some experimenting I figured outhow to install Ubuntu in the empty disk space and it all worked fine(GRUB took over my booting (recognized Vista automatically!) and Ubuntuloaded up fine).

Then I tried to install my GPU drivers andeverything went wrong.. For some reason Ubuntu wouldn't boot anymore(failed to load X-Server or something). I was completely lost andwanted to remove Ubuntu.

This is where things start to get really messy!

Ifyou simply remove the Ubuntu partition, GRUB (Linux boot loader) willstill be on your PC (in control). It will trip out, as the Ubuntupartition will be removed.. Bad thing!

So you need to restore your Master Boot Record (MBR) for Vista (so that Vista will handle the booting, not GRUB).

Googleonly pointed me to sites that explained how to REMOVE VISTA, whichisn't what I wanted. Many sites talked about the 'fixmbr' command, butthis is really only available in Windows XP.

So how do you restore your MBR for Windows Vista?

1. Put the Windows Vista installation disc in the disc drive, and then start the computer.
2. Press a key when you are prompted.
3. Select a language, a time, a currency, a keyboard or an input method, and then click Next.
4. Click Repair your computer.
5. Click the operating system that you want to repair, and then click Next.
6. In the System Recovery Options dialog box, click Command Prompt.
7. Type Bootrec.exe /FixMbr, and then press ENTER.

That'sit. Now when you reboot your PC, Vista will load automatically... Youcan now safely boot using your Ubuntu desktop CD, to use the built inGnome Partition Manager to remove your Ubuntu partition!

I installed Ubunto 9.0 AND when it came up it said, GRUB LOAD,no such partition, then at a prompt it says,grub rescue.


If you run a dual-boot system with Linux and Windows, this has happened to you. You had to do your monthly reinstall of Windows, and now you don’t see the linux bootloader anymore, so you can’t boot into Ubuntu or whatever flavor of linux you prefer.
Here’s the quick and easy way to re-enable Grub.
1) Boot off the LiveCD
2) Open a Terminal and type in the following commands, noting that the first command will put you into the grub “prompt”, and the next 3 commands will be executed there. Also note that hd0,0 implies the first hard drive and the first partition on that drive, which is where you probably installed grub to during installation. If not, then adjust accordingly.
sudo grub
> root (hd0,0)
> setup (hd0)
> exit
Reboot (removing the livecd), and your boot menu should be back.

Only read below if Windows is now missing from the boot menu
If you installed Ubuntu before you installed Windows, then Ubuntu will not have anything in the grub configuration for Windows. This is where you’ll have to do a bit of manual editing to the grub boot menu file.
If you open the file /boot/grub/menu.lst with the following command:
sudo gedit /boot/grub/menu.lst
You’ll see a sample section for Windows, which you’ll want to uncomment and add to the boot menu list in whatever position you want it in. (uncomment by removing the #’s)
# title Windows 95/98/NT/2000
# root (hd0,0)
# makeactive
# chainloader +1
Note that you should also verify that hd0,0 is the correct location for Windows. If you had installed Windows on the 4th partition on the drive, then you should change it to (hd0,3)

BOOT MGR MISSING


Rebuild the BCD store by using the Bootrec.exe tool If the previous method does not resolve the problem, you can rebuild the BCD store by using the Bootrec.exe tool in the Windows Recovery Environment. To do this, follow these steps: 1. Put the Windows Vista installation disc in the disc drive, and then start the computer. 2. Press a key when you are prompted. 3. Select a language, a time, a currency, and a keyboard or another input method, and then click Next. 4. Click Repair your computer. 5. Click the operating system that you want to repair, and then click Next. 6. In the System Recovery Options dialog box, click Command Prompt. 7. Type Bootrec /RebuildBcd , and then press ENTER. • If the Bootrec.exe tool runs successfully, it presents you with an installation path of a Windows directory. To add the entry to the BCD store, type Yes . A confirmation message appears that indicates the entry was added successfully. • If the Bootrec.exe tool cannot locate any missing Windows installations, you must remove the BCD store, and then you must re-create it. To do this, type the following commands in the order in which they are presented. Press ENTER after each command. Bcdedit /export C:\BCD_Backup ren c:\boot\bcd bcd.old Bootrec /rebuildbcd 8. Restart the computer.

Acer M5641: computer crashed, mbr is corrupted, 'CD/DVD Drivers..


Hello,

What I am going to say pertains to Windows XP (I cannot vouch it will work for Vista, because I do not have Vista).

Boot from the installation CD, Choose Repair installation. You will have access to the recovery console. Log in the Windows installation that is detected. You will be asked for the adminstrator password. Once logged in Type Help. In the list of commands available there is one called FIXMBR. Check its syntax by typing Help fixmbr, or even fixmbr ?
Type the correct command at the prompt and hit enter/return. It should fix it. After that Press CTRL ALT DEL to reboot.

If that does fix the mbr use another computer and query the microsoft knowledge base for Recovery Console (or the equivalent for Vista) and following the instructions.
Hope it helps.

You don't need to get a command prompt to format the hard drive.
Just boot up with the CD as the first boot device. Press F12 just after you switch on the laptop, then select the CD as the temporary boot device, insert the Windows XP install CD in the drive.
When the install process starts and displays the partitions, delete the existing partitions, then create a new partition, and then do a full NTFS format, not a quick format.
Now ou are on your way for a new Windows install.
