    Can't Boot from orig. drive after attaching/booting from other drive


    After I once attached another hard drive, containing another install of windows 7, and (accidentally!) booted from it, I cannot boot from my original drive. Even though I have now disconnected the other drive, every time I try to boot from my original drive, it fails, and I see:

    Reboot and Select proper Boot device
    or Insert Boot Media in selected Bot device and press a key
    How can I get my computer to boot off of my original drive? And why would once booting from another drive screw up my original drive??

    Also, if it's of any use / help - my new motherboard is a UEFI-enabled one, an ASUS Z77 Sabertooth...

    --------------------------

    For some background - I purchased a new motherboard recently, and decided to just install a fresh copy of windows 7 when I did so. I purchased and installed to a new hard drive... everything was working fine - it was booting, starting up, etc. Then, I decided I wanted to grab some files off of my old drive - so I shut the computer down, hooked it up using an enclosure + an esata cable, then restarted... on startup, it recognized my old (now external) drive, and booted off of that. I then restarted my computer, checked the boot options, and set it so it SHOULD boot off my new (internal)... but it still booted off my old (external) drive. Finally, I disconnected my old (external) drive completely... and that brings us to where I began: with my new (internal) drive completely unable to boot.

    Also, when I try inserting the windows 7 install disk, and selected "repair", it says there are no compatible versions of windows installed... whee!

    Any help would be appreciated...

    Ok, I guess I solved my own problem... going to post in case anybody else has a similar issue...

    I got it to boot by setting the boot priority of the "Windows Boot Manager" BEFORE the priority of my DVD-drive. I guess I'll have to manually go into my BIOS to change the settings every time I want to boot of a CD/DVD. Annoying... but it works, I guess...

    You can use the one time boot menu.
