No bootable device detected on first startup, second will be fine.

After trying the CrystalDiskInfo;
I would also check in BIOS - BIOS features - "Boot Mode Selection" and "Storage Boot Option Control".

Please post back a screenshot of Disk Mgmt as specified here: Disk Management - Post a Screen Capture Image

Try running a few Startup Repairs from WIn7 disk or REpair CD to see what it reports.

Sorry but I had to ask. Is the solution on Windows 8.1 and Windows 7 different even if the problem lies within the bios? thankyou for your response

Depends on the problem. If you want to post the requested screenshot we might be able to spot the problem as happens in about half of cases.

For the forgotten password - User Account - Reset Password in Windows 7

I wonder if you need to be trying startup repair from a win 8 repair disk or equivalent. I will wait for Greg to comment.

I remembered the password a while ago. I logged in before i go out to work. Maybe its better if I troubleshoot using win7 right? i know this is far away from the repair disk thingy. But if it helps, this is a screenshot of what we are using to asses a hard drive if its fit to be sold as secondhand good. Its called HDtune btw. It says its 100% healthy. Thanks for your help

Hmm, I am not convinced to call this a hardware fault or an OS misconfiguration to be honest.

Did you check AAM/APM of the HDD yet (post #8)?

Then I would try in order:
- use another power connector from the PSU (a different cable coming out) but not the same plug on the PSU. I hope this one is clear.
- Then I would find any SATA harddisk (maybe you have one laying around or ask friends) and remove your current one/s and see if it is recognized by BIOS, even install Win7 on it just to test
- if the issue continue with the other HDD too, either BIOS at fault or just somehow misconfigured. Does your BIOS have an option to delay start or similar?
