Windows 7 - How to add Windows 7 to boot manager?

i've had an interesting time with my computer lately and really could use some help to put myself at ease.

first of all i already have both XP(32) and Windows 7(64) installed but yesterday XP crapped out on me with a corrupted DLL file that didn't let me boot up into XP again.

i ran windows repair but because of a weird combination of unofficial sound drivers and the part of the installation process where all my devices(mouse, keyboard etc.) were seemingly cut off i couldn't proceed since i was prompted a choice i couldn't do anything with.

also, apparently the XP repair/installation process removes your old boot settings so i couldn't get into 7 either so i thought i was locked out from both of my drives though luckily i managed to solve it by doing a new XP install on top of the old one and could at least back up all my files before more things screwed up.

so basically i've got a new XP install and an old Windows 7 install but have no idea how to access Windows 7 on my other drive since the boot option was removed.

i was going to just install Windows 7 again but on top of all this when i boot up my Windows 7 CD, it comes to a blue screen with a mouse cursor and apparently just hangs with nothing happening.

so basically:

-is it possible to add Windows 7 to your boot manager from XP and if so, how?

-if that fails, how do you get past the blank/blue screen after booting up the Windows 7 CD? there were no problems when i first installed Windows 7.

thx alot.

Use Easy BCD to manually add the Win 7 entry
Download EasyBCD 2.0.2 - NeoSmart Technologies

okay after installing it, it shows my old boot list instead of the new one with the fresh XP install(remember i installed a new XP on top without formatting/removing the old one because i didn't want to lose my files)

old list:
earlier version of windows(XP)
Windows 7
Windows 7

the new boot list that doesn't show in easyBCD:
windows home premium(fresh install)
windows home premium(from my botched repair of the old windows which i can't boot into anyway)

what can i do from here to make it recognize the new list and add Windows 7 to that?

Reset the Boot configuration then add the missing entries

okay good news first:
after resetting and applying the new entries i managed to get into Windows 7 again.

the bad news is that using the automatic drive selection for detecting XP it boots me into the botched version of XP instead of the new one i installed.

i tried renaming the working XP folder to default windows(my fault for not just overwriting the damn thing but put it in a new folder "Windows1" instead) and it boots up but doesn't go past the blue welcome screen.

got any more suggestions?

this is probably the weirdest issue i've had to deal with on my computer so far.

Your XP installation might be corrupt

Did you run easy bcd from within the windows 7 install?

Well i just said screw it and went for another install of XP but this time deleting the previous install occupying the default windows XP folder... gonna install easy BCD again and then use the same method as before and see if automatic detection for XP enables me to boot into it now as well as 7(since 7 worked before i'm assuming it shouldn't give me any problems).

Again, did you try adding XP using EasyBCD from Windows 7? It works better.

no... i was already done reinstalling XP when the suggestion came.

anyways the method worked and i've got access to both 7 and XP now.

thx for every suggestion.
