Need to select the default Windows 7 OS at boot, cannot get into windows

[Cobra]

so, there was a problem with the bootup, and i popped in the windows 7 installation DVD, and repaired it(via system repair). all went well, i was able to get into windows. the "select which os to boot from" message popped up, so i disabled that and chose the wrong OS to be the default, the corrupted one [which is called "windows 7 home premium (recovered)]. i also, foolishly, set the timer to 0, so i can't even choose the "other" windows 7 os, the one that is not corrupt. also, bcedit does not work on DOS prompt. how can i get the default OS boot menu before bootup, again? thanks in advance

You now have 2 installs of Win7...
That being said at bootup immediately strt tapping F8 which will bring up the advanced boot menu...
From there you should be able to undo the things you chose poorly on...
