    Yes, as soon as I get home I will, I wont do anything on the meantime. You are not getting it, I have in total currently installed in my PC four storage drives. Three of them are SSSD's one being a 1TB where my games are, one being a 246 GB one where I installed the new Windows and then a 128 GB one where I have my old OS and previous configuration untouched. I also have a 1TB hard drive for massive storage.
    Thanks

    OK then, I have no idea why you can`t boot into the older ssd then, if you installed windows on the new ssd, you should now have what we call a dual boot and a dual boot screen where you can choose each version of windows 7, but you must have done something wrong.

    If you want the old ssd to boot again, simply unplug the new ssd and run startup repair until the old ssd boots again.

    You say you changed the setup, what exactly did you do ?

    Just for future reference, whenever you install windows you should unplug any other drives connected to the motherboard simply by unplugging its power plug.

    In your case maybe you should have cloned your old OS to the new SSD, unless you didn`t want to do that.

    Post the shot of DM when you can :)

    Yeah, that's what I am thinking. I already think I tried startup repair but nothing really changed, it just boot from the new SSD.
    I'm just assuming something changed, not that I did it on purpose or anything since evidently it boots another Windows.
    Definitely, I learned my lesson of unplugging everything before installing a new drive.
    I was wondering, what if I copy every file I've got from the old OS and put it into the new drive, the one that the reads Local Disk C: know? Will it make a huge trouble and problems with partitions if I try doing it?
    Well, as soon as I get home from chemotherapy I will send the DS shot. Really appreciate the patience and help guys.

    Do you refer to the OS or the type of disk?
    Yep mate that is exactly what I meant a DVD with Windows on it retail or OEM anyway doesn't really matter as the others are taking good care of you now.

    You have to unplug the new install of windows to try and run startup repair on the old one.

    Still waiting on that shot of DM

    OK, so Disk 1 is the drive that no longer boots, correct ?

    And Disk 3 is your new install that works fine, correct ?

    To my, it looks like the old install was done using EFI on a GPT Disk, and the new install was done in Legacy mode on a MBR Disk.

    Did you make any changes in the BIOS before you installed Windows 7 on the new SSD ?

    That' s correct, I'm booting the OS from disk 3 and have the old one in the 1.
    Excuse my ignorance but, what does it mean? Is there a solution or did I screw up?
    Not that I remember. I mean, I changed some boot options to see if I could start from the old OS but that was afterwards.
    Thanks again for the patience.

    If your new install was done with the Bios in Legacy mode, that is why you can not boot to the old install.

    You can`t boot into Lgecy and UEFI at the same time, without changing those options in the Bios first.

    So, in theory, all you should have to do is change the Bios back to UEFI then the other ssd should boot, but remember, that ssd has to be chosen to boot if it`s not setup as the 1st boot option in the bios, use the 1 time boot menu key (usually F8) all boards are different, to bring up the boot menu, then you just choose the older ssd and it should bootup fine.

    Excellent, I'll try that as soon as I get home and update you with the results. I should disconnect the new SSD before I do anything right?, and leave just the old one.
