If it's your DVD, then download a new copy and use your original licence key.

Get the correct copy of your windows 7 from here and make a bootable usb http://www.w7forums.com/official-windows-7-sp1-iso-image-downloads-t12325.html if that doesnt work reset the bios

And this is the official ISO to USB tool from Microsoft. I find it installs faster from DVD, but not by much.

The speed of the install is based on your USB speed.

I can install Windows 8 in 5min.

Interesting. I don't know why this has not occurred to me before. I guess it's finally time to buy a USB 3.0 stick

Make that I was able to install Windows 7 installed 7min on a USB 2.0

I think it's time for you get a proper USB flash drive :) Make sure that they are at least ~25MB/s read and write (also happens to be the max of USB 2.0). Of course that this is the sequential read/write speed. It's much slower for smaller files on both USB 2.0 and 3.0. You just have to check reviews, I guess :)
