Windows 7 is available in Beta version and it has some bugs as well as compatibility issues with other softwares. People installed it just for the sake of curiosity and now facing weird problems.
If you are one of them and want to uninstall Windows 7 from your PC then you can use following tutorial. It will be more helpful to those people who have dual boot systems and Windows XP installed on the PC.
You should not use this tutorial if you only have Windows 7 and Windows Vista in dual boot.
Steps to Uninstall Windows 7
- Start Windows XP.
- Insert Windows 7 ISO DVD into DVD drive.
- Press ‘Win + R’ to open Run command prompt.
- Type [DVD Drive Letter]:\boot\bootsect.exe /nt52 ALL /force and click on OK.
Note: Add the name of your DVD drive in [DVD Drive Letter] field.
- Remove DVD from your drive and reboot the system.
- Your computer will boot up with Windows XP installation.
- Now you can either format the drive containing Windows 7 or manually remove files of Windows 7.
- Finally remove Boot.BAK and BootSect.BAK from root system folder of Windows XP. Don’t delete these files if you have another operating system installed other than Windows XP.
Alternate Method: Simply format the drive that contains Windows 7 files and repair your system with Windows XP installation CD for any booting errors. 
Now you can easily access Windows XP without any reinstallation of OS. If you find any error or difficulty while uninstalling Windows 7, please let me know in the comment section.

good site!
I get the error message “E:bootbootsec.exe is not a valid Win32 application”
I suppose this is because I have a dual boot system with WindowsXP (32-bit) + Windows7 (64-bit). Any possible solution?
I think there is a problem with your operating system. Can you tell me your PC configuration?
Thanx for the reply but that’s ok.
I removed Windows 7 using EasyBCD. I though it was only for Vista & 7 but it works perfect at XP too…
Nice to hear that. If you find any problem with your OS again then do let me know.
What If I can’t find my Windows 7 Beta Disc?!?
That’s not a problem with the OS, you can’t run the 64 bit version of bootsec.exe from 32 bit Win XP. Documented at many sites.
I hear you Peter. A ‘Friend’ had a beta disc, and installed it on my computer on a seperate drive. I decided against Windows 7 for the time being, and now my ‘friend’ says he lost his disc. I have tried every other suggestions from numerous sites with no luck. Reformatted the drive to get rid of it, but it still stops at the ‘which system to boot too’ screen. My Xp install disc would not work. At the “r” option, it says ‘no disk drives found’, with no other options.
I have win xp on a hard disk, and i just installed win 7 on another. For security, i set first to boot, win xp(which by the way, i think will remain the best op. system ever). After a while, after i saw how crappy it is, i unninstaled win 7. Why is crappy win 7, because very few drivers on the originally instalation disk, worked(sound driver, graphic, webcam, and very many utillities, including my antivirus…) . I searched one month on specialized sites, and very little solutions i found. Microsoft is bullshiting us, with stupid solutions… After i formatted the hard disk in which was win 7…, after rebooting appeared the dual sytem booting message, despite the non-existent win 7… I followed up the instruction above, and like a miracle, this ennoying message dissapeared, and my computer boot normally like before. It worked… Thousand thanks, for the tutorial, editor! ♣
You’re welcome.
Try booting directly to the CD – you may need to change the boot order in BIOS. Then you should be able to install XP.

Follow this path – Control Panel -> System and Maintenance -> System -> Advanced System Settings -> Advanced from the tab and click Settings in Startup and Recovery. Now, uncheck this option – Time to display list of operating systems. Click on Ok.
