As I have understood: (Correct me if I am wrong.)

PC #1: There is a problem with the hard drive. In addition you had run Diskpart Clean.

PC #2: No problem with the PC. Yet you had run Diskpart Clean. So it no longer boots.

Immediately we shall take up PC #2.

Follow these instructions to the dot. Do not deviate and attempt anything on your own. I repeat Do not deviate and attempt anything on your own. If in doubt, stop and ask for guidance.

1. Download Partition Wizard bootable CD ISO from Bootable Partition Manger | MiniTool Partition Wizard Bootable Edition. It is pwhe8.1.iso (48.3 MB)
2. Burn the ISO to a CD
3. Safely remove any and all USB drives/ Flash drives on PC#2 and boot into Partition Wizard on the CD, using the one time boot menu.
4. Partition Wizard Main screen will show your system drive. Rightclick on the drive icon on the left in the drive map > Rebuild MBR > Apply > Yes > OK. This will write the MBR code to the first Sector.
5.Again Rightclick on the drive icon on the left in the drive map > Partition Recovery > Full Disk > Next > Quick Scan > Next. This will after the Quick Scan is completed will bring up a screen showing all the partitions found.
6. Post a screenshot for further instructions on selecting the correct partitions.

( In general you will select only those partitions which when ticked will show the drive preview map at the bottom as it was before without any unallocated space.)

Thanks for the reply but it is a little to late for PC 2, it was my room mates PC and he never used it and we already went through drama with DBANing it and reinstalling then later i corrupted the harddrive and just bougth a new one because the data on there wasn't anything important. So now i have already followed Gregrockers advice and i followed the instructions to clean reinstall windows on it, so thats taken care of. The main focus now is data recovery on PC one in which you are correct in your understanding, there was a problem with the hard drive and in addition i ran clean command on it.
Now should i follow your advice for PC 2 but try it on PC one?

And now @gregrocker if i clean reinstall windows on PC #1, would i still be able to recover data, and if not, would a professional data recovery company still be able too..possibly?

Also, just confirming with the rest of anyone reading this, is Malwarebytes and Microsoft Security essentials all ill really need? Because thats all ill put on there if it is. All i do on my computer is school research (occasionally) and most watch movies on those websites, and play games, if you guys have any advice on the best settings that would also be helpful.

OK PC#2 is now off from our attention.

On PC #1:

If you reinstall Windows now, all the data in it will be overwritten and you will lose all that data. So reinsatall only after data recovery attempt.

Yes, try the Partition Wizard as detailed in my previous post on your PC #1.

Let us see where it takes us.

If we can bring it back to the condition as it was prior to the diskpart clean, we can assess and see what best can be done.

( Running diskpart clean wipes the first 2048 sectors including the first sector which contains the MBR code and partition table.It does not delete the Partition Boot Record - which is the first sector of each partition and any data in that partition. Writing the MBR code and then the partition table if PW finds the partition/s should bring it back to the original condition. Then it should be possible to recover the data hopefully - provided your HDD has not deteriorated due to creation of bad sectors)

Have you browsed into the partition which contained the data from the Win7 disk explorer using Copy & Paste - in Windows Recovery Console?

Once there did you find your User name, then under the User profile find your User folders to look for the data? Or was the data elsewhere?

I have never seen the data not be recoverable even when Win7 is not bootable. Only if it has been formatted is the data not normally able to be copied out.

Ok, so I've got two of you telling me things, which should i attempt first, if it matters? I might also have to get back to you guys tomorrow because im getting burned out, but THANK YOU SO MUCH for working with me, I may or might attempt these solutions tonight, but i will definitely post back progress, don't wait up (in case you might be, idk.)

Yes, you can also try what Greg has suggested.

And yes, it will also help if we know how many partitions you had on your system drive and how Windows was installed in it.( Some people do not have any partitions and all data is written on to the C drive. Some people create additional partitions for data keeping only Windows on the C drive/partition.How is yours?)

Try Greg's suggestion first. You can go to sleep and continue tomorrow morning. Greg also needs to go to sleep.

I also need to go out Sunday shopping.

I didnt put any partitions on it i just wrote to the C: drive (custom build) but yea ill check this again tomorrow, thanks again and good night guys.

I just tried the method you linked me too but the HDD doesnt show up all i see is Boot X and the CD :/

Try changing cables, SATA port to see if you can get the HD detected in BIOS setup.

Once detected try again rescuiing your data, then run the maker's HD Diagnostic extended CD scan, followed by a full Disk Check.

I am currently already running Partition Recovery Wizard from Jumanjis suggestion, should i let that finish and then (if it doesnt work) try your suggestion again?

Also, the hard drive problem occurred directly after the computer restarted from a Check disk scan (error 0xc000000f the required device is inaccessible) and the scan went fine.
