BootMGR is missing problem

Ive tried installing Windows 7 from a bootable DVD, unfortunately, there were some files missing or corrupted during installation
then I gave up and had in mind of installing windows XP again, but I found out that even though the XP install is bootable, it wont start because of the BootMgr issue.. ( I've tried selecting the cd/dvd rom at the boot menu at start and it wouldnt work )
I've been seraching for a solution to resolve this problem, I've done a startup repair, but it says that it could not fix the problem, it also asks if I have some external device connected which I don't
on the above tab of the system repair it says something like Windows could not fix the problem etc.
and below it asks me if I have some external device connected , and then asks me to remove it for startup repair to work
I've tried installing windows XP from a bootable CD but it won't start, I just dont see a reason to use windows 7 anymore..
what should I do?

Don't give up on 7. It is awesome.

You have a bad disc burn issue. Create a USB key instead from the .iso and install from that.

If you downloaded the .iso from a torrent, you have a bad .iso. Download only from official source, being Microsoft.

If you are on Windows XP and planning to UPGRADE...


YOU MUST DO A CLEAN INSTALL. There is no upgrade path. There are user migration tools you can use, but you will need to backup your files and do a clean install.

I have seen several threads about this and just want to clarify. The upgrade from Windows Vista is a valid upgrade path, but Windows XP to Windows 7 is not
