Having missed this & not knowing wtf youre on about chup....
I removed ubuntu from my vista dual boot & it screwed me right up but I fixed it:
1. Start your computer from the Windows Vista Installation DVD
2. Press a key when prompted to continue
3. Choose your language, time, keyboard and click Next:
Select language and preferences
4. Next, click "Repair your Computer":
Repair your computer
5. Now, from the System Recovery Options dialog, select the "Operating System" you want to repair, then click Next:
System recovery options, choosing your Operating system
6. From the "Choose a Recovery Tool" dialog menu, select "Command Prompt":
Recovery Tool Command Prompt
7. Type the following into the "Command Prompt Window":
bootrec.exe /fixmbr
bootrec.exe /fixboot
8. Remove the Vista Installation DVD and restart your PC.
If all goes well, this process should have enabled you to restore your Vista MBR and you should now be able to boot back into your Windows Vista Operating system.
thats my ' how to' but it worked for me.. oh yeah, I dont even use vista anymore, oh well
