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 Christmas 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.

Uninstall Ubuntu Dual boot and Repairing Dual Boot in Windows 10

Hello.

I had dual-booted my Dell laptop which came with preinstalled Windows 10. I had dual booted with Ubuntu 16.04 by creating a partition on the disk. To remove this dual boot, i.e. I only wanted to keep Windows 10, I formatted the disk, drive F(in my case),
where Ubuntu was stored. But, now whenever I boot my system, a black grub screen comes with the following message:

"Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists possible device completions.

grub> _"

Upon writing 'exit', I am able to enter Windows.

1. I wish to know the reason behind it and how it can be removed.

2. I found this site, Uninstall Ubuntu Dual boot, I went ahead and performed all the steps. But somehow
ended up with this error.

Also, I saw your reply on this thread Redirecting.
But it did not help me to remove my error. I will really appreciate your help in removing this error.

Thank you.
