Windows 7 - Not booting up

[nitinpai]

Hi! I was trying to make a bootable Windows 7 USB using WinToFlash. The application requested the source (location of OS) and target (USB drive) which I furnished after which it proceeded to copy the data onto the USB drive. On completion the system restarted on its own but did not boot up - only the letter 'J' keeps flashing on the top left of the black screen. Nothing happens beyond this point.

- I've tried restarting a multiple times but the same result.

- I've tried booting from the DVD drive by making use of the Windows installtion disks but the setup fails of recognize any Windows installation or even the harddisk.

Could you please help? Should I try to intalled a driver so Windows setup can recognize the harddisk?

My configuration is as under-

HP ProBook 4420s

Windows 7 (installed from a DVD)

Thanks!

1 - Are you trying to install FROM the USB or are you trying to install TO the USB?

2 - to quote jaclaz -

You used an app (WintoFlash) that we:

* don't use

* do not know

* do not recommend

WintoFlash has their OWN Forum for problems. Have you tried OUR recommended methods for installing FROM USB?

Here is a Tutorial on how to install TO a USB...
