Windows 7: Windows 7 Will Only Boot if Boot Drive is the only Drive Plugged In

Windows 7 Will Only Boot if Boot Drive is the only Drive Plugged In

I have a Windows 7 install on a 60gb SSD (assigned to C: in Windows), and a 3 other drives just for storage, and programs. Windows will only boot if the SSD is the only one plugged in. BCD lists this as my only entry, and is calling the C: drive to boot.
However when I load my Windows cd, this drive is assigned to E: when all my other drives are plugged in. I'm not sure why its doing this, but could this be the problem and is there a way to fix it?
Thanks

We need to see a screenshot of your Disk Managment. Click on the Windows button in the lower left of your screen and type on the space above the button "Disk Management" without the quotes and hit enter. The Disk Management will pop up. Expand the columns so we can read all of the print.

I have all my drives unplugged right now to boot in, with them plugged in I may not be able to boot. I will try though and report back.

If you can't boot with them plugged in, boot with them unplugged, plug them in and make your screenshot.

If you can't boot with them plugged in, boot with them unplugged, plug them in and make your screenshot.
Is it safe to do that? I have hot-swap turned on in my bios.

It looks like Disks 3 and 4 were former System disks which held smaller boot partitions at the beginning, then afterwards they were not wiped of boot code or even deleted before reformatting for data.

As a result you have the risk of stray boot code interfering at boot from those data drives, and you also have a Dynamic Disk on Disk 3 which is only meant to span a partition across multiple HD's.

To resolve this I would move the data off of each to wipe it with Diskpart Clean Command then repartition in Disk Mgmt: Partition or Volume - Create New

Once you've done this post back another screenshot and how it boots now.

Okay update:

I've had it booting for the last few weeks fine (a few times it didn't booting into an ubuntu live cd alone fixed it). Now it won't even boot at all even with just my boot drive plugged in. There is only a black screen on boot up, hitting F8 for safe mode doesn't do anything. Windows startup repair doesn't find a problem and my BCDEDIT appears correct, however rebuildbcd doesn't find any instance of Windows 7.

Thanks

Disk 3 is Dynamic. Take it out and see if you can boot OK.
