Windows 7: Windows 7 HDD won't boot but I'm able to access through W8 SSD

After some messing with boot priority, I am able to detect my HDD in the bios but even after disabling every other device and trying to boot to it specifically, I get an error that there is nothing found. I'd figure it's a loose cable but I'm able to access everything on the drive fine through my Windows 8 SSD installation.

Can anyone throw out any suggestions, I know this sounds pretty vague but please help me and feel free to ask any questions.

I've tried clearing CMOS and restoring windows to an earlier point when things were fine and dandy, no luck so far



One thing I can think of is I removed 2 100mg partitions of my current drive? Not quite able to pinpoint something specific I did but I was able to boot to either drive earlier this evening.. upgrading my bios firmware actually resolved a BSOD issue I was having earlier so I've already attempted that

Please complete/update your pc specs, so we can help you.

exact boot error please

Intel i5-3570 CPU @ 3.40GHz (4 CPUs) 3.80GHz
Gigabyte-z77x-ud3h Mobo
500gb HDD Windows 7 64bit
128gb SSD Windows 8 64bit
8 GB Ram
GTX 670

When I disable all drives but my 500gb Windows 7 one, I get this message when I attempt to boot
"Reboot and Select proper Boot device or insert Boot Media in selected Boot device or press a key"

Change boot device order to DVD then 500GB disk
Boot into Windows 7 recovery environment System Recovery Options

Does it see your Windows 7? If so select it. Then enter command prompt
then:
Both commands succesfull? Now try boot normally again

If that is the drive you are using to boot -- your removed the partition containing the boot loader files -- so, of course, it will not boot.

You shouldn't just blindly remove partitions without first determining what's in them and their usage.

please post full blown screenshot of disk management. Can be taken from within win8

I love you

Windows 7 HDD working again.. it wasn't detecting Windows 7 in the Startup repair and the bootrec /fixboot command didn't work (bootrec /fixmbr did) but whatever else I did managed to recover my primary operating system so I appreciate your assistance very much.

Now I can get to work today and won't have to do it from Windows 8 SSD

Thank you so much! Surprised how fast and simple it was, I had the Windows 7 startup repair in my list of options to try but you helped guide me in the right direction

Disk management on my Windows 7 shows 2 small partitions, I must have just hid them on this drive somehow but the other one I full blown deleted them when I just wanted to hide them, I need to look into howto do that

bootrec/fixboot didn't work because Windows 7 wasn't detected (don't know why) so recovery doesn't know what to fix!

bootrec/fixmbr works because he knows what drive you selected to boot from. Did you do more to solve the issue, for example startup repair?

Post screenshot of disk management please

When booted in Windows 7, start an Elevated Command Prompt

Post that output as well please
