Windows 7 ultimate instalation problems 8007045d

He everybody,

I've got a problem.

I got an old pc and once every 6 months i re- instal my windows 7 to keep it up speed.

This time i made a big mistake. While instaling i had cleared out all my drives ( c and d). Thanks to this im not able to run my pc normal. Cause it keeps giving me a message bootmgr is missing press ctrl+alt+del to restart.

And if i try to instal windows it starts unpacking till 5% and then i get a message not able to instal code: 8007045d.

I got no clue what to do now.

Please help!

Unplug all other HD's and peripherals, boot the Win7 DVD, follow these steps to get a Perfect reinstall: Reinstalling Windows 7

The bootmgr error is because the DVD is not booting and it is trying to start the empty HD. Make sure DVD drive is set to boot first in BIOS setup, or use the one-time BIOS Boot menu key to trigger it at boot.

So correct me if im wrong. But i tak out my hds and instal it?

All except the target HD, then delete everything on it using the booted installer as shown in the steps I gave you.

Ill be home in about an hour. And im gonna try that out. But, if i do that i would be able to acces windows? Clean my drives and re isntal? Cause both my drives dont got any files on it any more including my system files?
