I used my Linux disk to delete the bootmgr and bcd files. I did subsequently get the "bootmgr missing" msg. Them I went into the recovery environment and used bootrec as you suggest. Now it actually tries to boot (a little progress), but always goes immediately to the Startup Repair box. After "attempting repairs", it waits 30 seconds and reboots. Does this over and over. I have let it run for an hour or so with this cyclic behaviour.
Thanks for your help, but there must be something wrong which your fix does not cover. I am going to fish out salvageable files (documents and pictures) with Linux, do a fresh installation of Win7, and restore the salvaged files. This is very annoying and time consuming, so I was looking for an easier way. I have found there seldom is in these instances. I guess your method is worth a try first, but in this case it was not to be!
