Windows 7: Reboot and select proper boot device error.

I took my CPU to a friends place and figured out that there is somethin wrong with my dvd drive. But why cant i boot using the pen drive? it boots in my friend's pc..if that could work i could have an OS runnin..thanx a lot greg..

Sometimes USB stick won't boot using one method and you have to use another: http://www.youtube.com/watch?v=srOoGhm-jcI
Windows 7 USB/DVD Download Tool

Does the stick show up on one-time Boot Menu accessed by tapping key given on first bootup menu? Sometimes it is listed under Hard Drives. It should make itself apparent there and on the BIOS boot order menu once plugged in but not always under the USB listing.

Try install to your HD in your friend's computer with his HD's unplugged. I do this when I dont' have time to troubleshoot problem install, and so far it has worked every time - swapping out drivers and requesting several restarts when returned to problem machine.

Then when you have it setup as you like save a Windows 7 backup image externally so you never have to reinstall. You will need a bootable Repair CD, tho, which also can be put on stick.

I bought a new dvd drive and installed windows. I will go through the link u gave me, thank you very much Greg
