uninstalling windows xp from dual boot

Log in from Windows 7 and format the drive in which Windows XP is installed after backing up all data on Windows-XP containing drive.
If you erase boot sector by mistake, then boot from your Window CD/DVD and then go to recovery console and then at the prompt, type -

bootcfg /scan -> Scans for windows Os
bootcfg /rebuild -> Rebuilds boot sector
or try -
fixmbr
fixboot

Yeah. It'll will do.
PS - You'll have to do that using Admin priviledges!

thank you.i selected win 7 as default operating system and everything is working fine but i just wanted to know is there any way to permanently remove that winxp from boot file.

There is a software which can Edit the bootloader in Win7. Google it.

On the same 'Startup and Recovery' tab, you'll also see 'Edit' button under the 'System Startup' section. Clicking on this will open the boot.ini file, which might lok like this -

[boot loader]
timeout=15
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect

I'm using single OS so only one OS is seen but in your case there will be 2 OSs. From there you can remove the statements refering to Win XP (in my case multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect)

Don't erase the statements refering to Windows 7, though! Be careful.

^^ That option is not available in Win7.

Unless you are not too hype about removing Windows XP from the boot loader, let it be there otherwise you'll end up doing some mistake and erasing your bootloader.

If you really want to do so, you might find some useful information here -

Here is the software: Download EasyBCD 2.0.2 - NeoSmart Technologies

thank you.i better leave it as it is.
