Hi all, I have been running W7 for a few weeks and all has been well, but today I get 'disk boot failure'. Insert rescue disk, run startup repair, finds nothing wrong, so do a reboot with rescue CD still in drive. Don't touch keyboard at 'any key to boot from dvd' and it boots into W7 perfectly. Tried various bootrec option and such, but still will only boot with CD installed. So EasyBCD sounds like it might find the problem; but when I start it up I get 'boot configuration data store could not be opened' and invites me to manually load a BCD registry. Now I'm struggling : suggestions please.
