dual boot xp and ubuntu

I had that problem a few months ago, but dual-booting is really easy. I am currently dual-booting Vista and Ubuntu 8.04 Hardy Heron. Use this website here for a guide to dual-booting XP and Ubuntu: APC’s February 2023 issue is on sale now! (I actually did not use this guide at all, but I did pretty much the same thing!)

If you are unable to get your boot working with this guide, reply to this message, and I will write out a step-by-step guide, but it will involve you already having a partition set out for XP (as in you are not already using your entire hard drive space for XP alone.) Even though I write the guide with experience from Vista, it will work with XP

 

Unable to boot Windows after installing Ubuntu as dual boot

Hi Neeraj,



Thank you for writing to Microsoft Community Forums.



I understand that how difficult it can be when Windows does not boot properly.



Since you are unable to boot Windows after installing Ubuntu, I would suggest you to try rebuilding BCD file and see if that helps.

1. Create a bootable media and boot the PC
   using the media.
   
2. On the Install Windows screen, select
   Next > Repair your computer.
   
3. On the System Recovery Options screen, select
   Troubleshoot> Advanced options >
   Command Prompt.
   
4. Now type in the commands and hit enter:
   BOOTREC /FIXMBR
   
   BOOTREC /FIXBOOT
   
   BOOTREC /scanos
   
   BOOTREC /rebuildbcd
   
5. Restart the PC.
   

If the issue persists, please get back to us with the results of the troubleshooting steps to assist you further.

Removed Ubuntu

Have you ever tried removing Ubuntu from boot list with msconfig? Which is much easier that way.

> In the Cortana search bar, type MSCONFIG and press Enter.

> On the System Configuration box, go to the Boot tab.

> From the list of available operating systems, click to select the one that you want to remove.

> Click the Delete button present below the listbox.

> Confirm your action when prompted.

> Restart the computer to check if the issue is resolved.

Here is an answer is for those with UEFI who have deleted the Ubuntu partitions before removing grub.

Uninstall GRUB and use Windows bootloader
