Windows 7: Formatted HD, BOOTMGR missing

Formatted HD, BOOTMGR missing

well firstly i'd like to say hello!

I would also like to mention that i did do an extensive search before posting.

Alrighty. Basically what originally happened was that i tried installing windows 7 off of my hard drive and during the "completing installation" phase the computer lost power and was shut down. turning the computer back on i had a screen which said something of the likes of set up is starting---- From then on i was in a infinite boot loop where it would give me a set up screen and restart. I desperately needed to backup my files which i did not bother to do so . I used my secondary desktop running vista, plugged in my other hard drive and backed up all my files successfully.

Here comes trouble. I thought i would format the disk since i was done backing up all my data and i would go right on ahead and install a fresh windows 7 via the CD. I go into bios and set the windows CD to boot and i unplug my vista hard drive and leave only the formatted 1TB HD plugged in. And now i get the "BOOTMGR is missing" error. As i have read it's due to deleting EVERYTHING off the hard drive including the...bootmanager. Now with the tools that i hold (mobo with bios access, windows 7 installation CD, another hard drive with Vista) HOWWWWWWW shall i go about getting my hard drive ready to install a fresh copy of windows 7. I have the retail cd, i have another HD with vista if needed, and i have the clean hard drive which i would wish to install windows 7.

And before anyone asks me to set my bios to boot via the CD first and put in the disc and let it work it's magic, i would like to point out that it still gives me a BOOTMGR error. It asks me to press a key to load from the CD and then i get the error that i know is coming.

Any help is appreciated.

The error only means BIOS is skipping the DVD drive and trying to boot a formatted HD.

Wipe the HD with Diskpart Clean Command from the DVD by pressing Shift + F10 at first screen or entering System Recovery Options.

This should force the installer to autostart on its own, however you may need to confirm the installer and assure you are booting correctly:
