What's it been doing for 6 hours ?
Did it get to the repair dialogue, or is it still "loading files".
If the latter, then it's having problems locating/reading your HDD.
As Mak said, that could indicate big problems with your HDD, or (if you're lucky) it may be as simple as bad contacts preventing the read.
Try disconnecting/reconnecting all the HDD cables several times to clean up the contacts. (or eject/reinsert for laptop)
Thanks for your reply. I was mainly concerned about the never-ending Repair process... Now I've booted the laptop with an Ubuntu DVD and managed to copy all the documents to a safe place
Also, I created a System recovery Disc from another PC using Windows 7, and tried to recover the original system, butr it got stuck again in the system selection Dialog, showing the correct partition (C

and System Name (Microsoft Windows etc) but the Next butto it never gets enabled as the process does never completes... As you guys said, it seems a severe hardware error with the HDD instead of a corrupt boot information.
I'll try to progress with yout indications, but since this is a brand-new laptop, I'll bring back it to the store and have a refund or replacement or have it sent to Technical Dept....
Thanks all!
Addendum:
More....
I followed instructions in
http://neosmart.net/wiki/display/EBCD/Recovering+the+Windows+Bootloader+from+the+DVD (Option 2 first, and then 3) and now I get error saying Winloader.exec can't be loaded, Error 0XC000000F.
EasyBCD stilll gets stuck when attempting automatic repair or in the Automatic Recovey Options dialog...
Addendum:
BW, I also removed the HD and cleaned the contacts. It's a new laptop, but still i did it. No results either....
