XP

Boot on your Windows XP installation CD or XP Recovery console. You will get to a

part where it asks if you want to repair or recover. To do so, press "r". If prompted, enter

your Windows XP administrator password. This will leave you at at a command line, so

type in the following two commands:

fixboot

fixmbr

Then type

exit

Then remove your XP cd. If everything has gone well, you should come to your XP

bootloader.

Windows Vista or 7 or 8

First boot on your Windows Vista/7/8 installation DVD.

If you have one of the many OEM computers that didn't come with a Windows

installation disk, you can get the same effect with a Windows repair disk, which you can

download(eg Win7-32bit, Win7 64bit) or createfrom another Windows Vista/7/8

computer (see this page for Win7 and Make your own Windows repairCD, and

Windows 8 UEFI repair USB must be FAT32, other Win8 guide). When you get to the

Regional settings, select your Location/Keyboard setting then click next. On the nextpage, click on "Repair your computer." On the next page, if it finds your Windows

installation, make sure it is UNSELECTED before clicking next. Then click on

"Command prompt". From there, type in the following 2 commands:

bootrec.exe /fixboot

bootrec.exe /fixmbr

Now close the two windows and click "Restart." Take out your Windows DVD and

hopefully, you will be left with your Windows bootloader.

How to partially fix the Windows

bootloader using an Ubuntu CD

Note:these methods will work on Legacy firmwares (not UEFI), if Windows boot files

are not broken, and if the boot sector of the Windows boot partition is healthy. In other

cases, you will need a Windows installation or repair disc as described above.

Via the Boot-Repair graphical tool

Run Boot-Repair from a liveCD, click "Advanced options", tick "Restore MBR", click "Apply".

This will automatically restore a generic syslinux MBR, and set the boot flag on the Windows

boot partition. This will also tell you if the Windows bootsector needs repair (see this tutorial).

Via command lines

1. Boot from the live CD (or live USB) of any recent version of Ubuntu and choose Try

Ubuntu to get to the live desktop

2. Check that the partition from which Windows boots has the 'boot' flag. For XP and Vista,

this is normally the main C: partition. Windows 7 usually (but not always) has a separate boot

partition of 100-200 MB in size with the partition label SYSTEM. There are also more exotic

configurations where two versions of Windows have been installed to the same hard drive, or

where the main Windows partition is a logical one. In these cases there will be a single primary

partition with the Windows boot files which needs to be marked as active, and you will need to

identify which this is. Once you have done so, open Gparted and see if boot is listed under the

flags column for that partition. If not, highlight the partition and go to Partition menu Manage

Flags, tick the tick-box for boot and then close that window and close Gparted.

3. Both methods below assume that the boot drive is designated /dev/sda in Ubuntu. This is

almost always so, but with some unusual BIOS configurations where there is more than one hard

drive, the boot drive may be other than /dev/sda. In such cases you will need to adjust the

command appropriately.

If internet connectivity available, open a terminal and run these commands:

sudo apt-get install lilo

sudo lilo -M /dev/sda mbr

If no Internet connection: recent versions of Ubuntu include the file /usr/lib/syslinux/mbr.bin

which is 440 bytes in length and simply needs to be written to the beginning of the mbr with this

terminal command. WARNING! Be very careful with this command and check for typos beforerunning it.

sudo dd if=/usr/lib/syslinux/mbr.bin of=/dev/sda

4. Now reboot, remove the Ubuntu CD and you should reboot straight into Windows.
