windows 7 cannot boot - cannot run chkdsk or diskpart

Hi,

i attempted a dual boot of debian and windows 7 yesterday, on a HP laptop with a single HD. this is where ive come a cropper as i think ive installed grub into the windows partition - and thus now it cannot boot windows.

i have a recovery disk, but cannot run chkdsk, scannow and diskpart does not let me select any volume other than the recovery disk itself.

example output;

chkdsk /f
the type of the file system is NTFS.
cannot lock current drive.
windows cannot run .... because it is write protected.

sfc /scannow
there is a system repair ... restart and run again (restarting doesnt change this)

diskpart
list disk
Disk 0 Invalid 232GB Dyn (*)

list volume (lists the CD rom only)

list partition
Part 1 Dynamic Data 992KB 31KB
Part 2 Dynamic Data 199MB 1024KB
Part 3 Dynamic Data 179GB 200MB
Part 4 Primary 53GB 179GB

bootrec /fixmbr
successful

bootrec /fixboot
the volume does not contain a recognized file system

bootsect /nt60 all /force
\Device\HardDiskVolume1

could not open the volume root: the parameter is incorrect.




those commands are all i can find to fix the problem and none of them do. i DO NOT HAVE a installation disc as it's a HP with windows pre installed on it.


HELP please .....

Hi, thanks for replying.

bootsect /nt60 all /force /mbr
