I recently install ubuntu 13.10 in dual boot with windows 7.
when i startup grub loads fine, and so does ubuntu.
but if i select windows from grub i get an error message, something like:

windows failed to start. A recent hardware or software <bla bla bla...>
error code:  "0xc000000f"

my workaround:
i reverted the mbr to a backup i created before installing ubuntu. now windows loads ok. (no grub or ubuntu available now of course...)
so this is obviously an issue with grub not loading windows properly, but i have no clue how to fix it. :(

additional info:
hp Folio 9470m
SDD hard-drive
windows seems to startup from a small partition (102MB) labelled "boot" on the beginning of the hard drive.
