Cannot boot into Windows but only BIOS

My goal was to extend my C: drive by shrinking my D: drive and then using that unallocated space for extending C. I have a single HDD. Using Disk Management, I have not reached my goal yet but in the process I switched the disk from Basic to Dynamic, thinking that dynamic disk would allow me to extend a drive with an area that is not contiguous. (adjacent to C)
I realized that switching to dynamic disk did not allow me to extend the C: drive. So I wanted to switch back to Basic disk type but I did not see a way to do so in Disk Management so I used a program called AOMEI Partition Assistant which includes a Dynamic Disk Converter. After running this disk converter that supposedly converts from Dynamic back to Basic, I was not able to boot into Windows after restarting.

At the moment, I am not sure how to extend my drive but my immediate problem is that I cannot boot into Windows anymore. The system boots straight to BIOS even though I have checked the single HDD that contains the OS/boot files is visible and that is in the first boot priority.

Can you take a look at the screenshots I took from my BIOS and tell me what the issue is?

Re: boot into BIOS

If you didn't change anything in the BIOS, it's unlikely there's an error in the settings. Anyway, reset it to defaults and - if the BIOS is the cause - it should be fine.

Does it still boot from the recovery media or the Windows install disc you need to fix the mess on your hard disk?

Re: boot into BIOS

Do you mean recovery media like a recovery disk? My computer did not come with one. Dang it, now I am regretting not creating one myself. I think you can do so easily on Windows 8.1?
What if I have a backup of my system image? Can that be restored through the BIOS?

Re: backup of system image

Restoring that backup depends on how you made it. For Acronis, for example, you boot from their Linux based CD to do the recovery.

Extract drive, backup data and restore OS

Reload the OS, at this point.

There is the option to clone or make an exact replica of your data drive before attempting conversion with these tools. Such an option allows reverse changes. Of course if that had been pursued, you probably wouldn't be posting this issue as you'd be able to restore the backup image to the original drive.

It's possible to save the OS in its existing format on the drive, but for the sake of your time based on the kinds of scenario you've pursued, reload the OS.

Next time, close the OS partition to another disk drive or image before attempting one-way flights of no return which may also permanently wreck end-user data as well.
