Need to select the default Windows 7 OS at boot, cannot boot into win7

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 in DOS prompt. how can i get the default OS boot menu before bootup, again? thanks in advance

Boot tapping F8 multiple times, let's say every half second. Do you see bootmenu? If so select to write OS! If succeeded in win7 run msconfig. There you can delete the old "corrupt" OS from the list and set the timeout to 10 seconds for example

F8 brings up the general device boot menu (boot from CD, Hard drive, etc)...

Or use EasyBCD.

Maybe you can select "hard drive" there. Tehn again fast tapping F8 multiple times, let's say every half second.

This will not help for operating systems on the same hard drive. If you manage to get into 1 of the systems use EasyBCD to edit your boot choices.

Couldn't you load the command prompt go into the partition manager (diskpart I think is the command) and change your active partition to the one with the OS you want?

Boot into recovery environment where "startup repair" is one of the options. Click on "Command prompt". A black screen opens.

Code:

bootmgr/set {bootmgr} timeout 10

Now reboot and the bootmenu is there again. Use msconfig afterwards as told you before

thank you, kind sir. i was not able to get into safe mode with command prompt. also, putting the windows 7 disc in and trying to repair again, and choosing either windows 7 boot partition yielded something along the lines of "the current version of windows is different from the one on the disc" and it would not attempt the startup repair again, on either partition.
