having major problems installing win7 home pre 64bit OS

And by "major problems" you mean exactly what?

[dinkyfish]

Itried to install win 7 os and it kept saying couldnt find driver and would go back to select parametr and select custom and try install again
now the pc saysbootMGR is missing press control +alt+del to restart

[EzyStvy]

It could find a driver or a hard drive?

If it can't find a driver it should have told you which one.

If this is happening during initial installation it could be one of the following causing the error:
1. the hard drive is not connected properly, go into the bios to check see if the motherboard is detecting the hard drive.
2. if the hard drive is detected then it could be your optical drive, SATA/IDE controller or possibly the hard drive failing (this happens even when they are new).
If you already installed 7 successfully then this started happening, what you need to do then is do a windows repair.
I hope this helps you out!

Are you installing Windows on a blank hard drive by booting with a genuine Microsoft Windows 7 DVD?
