Windows 8 CD and Bootable USB, Command Prompt (DISKPART), Reset PC
Hello guys! I badly need some help... I have a very big problem with my PC and it all started yesterday. I've upgraded my PC to Windows 10, it seems okay at first but a BSOD (memory_management) occurred after a few minutes. So, I've decided to RESET the PC. The process lasts for 3hrs and is successful. After that, Windows 10 installation has started. It went up quickly to 10% and got stuck for almost 2hrs. Then a message popped out (I can't remember the message though) and it all went black. I have no choice but to do a "hard shutdown". Windows then ran the automatic repair but failed. Reinstalling Windows 8 didn't worked, no hard drive detected. Both "Reset your PC" (Unable to reset your PC. A required drive partition is missing) and "Refresh your PC" (The drive where Windows is installed is locked. Unlock the drive and try again) didn't worked either. I've also tried to fix it in command prompt; DISKPART status: no media, size: 0, free: 0. I ran HP Hardware Diagnostics awhile ago; S.M.A.R.T. Test-Failed Error - 303. :( I've run out of ideas guys. :( I should've followed my gut instinct to do a clean install instead of upgrading.

Because Win10 create a new hidden partition, so in some systems like mine , the other partition "adresses" are modified (WIM stuff). Anyway i never use those features.

I've run out of ideas guys. :( I should've followed my gut instinct to do a clean install instead of upgrading.

If you don't have valuable datas to retrieve, delete the old Windows partition and those you have may created (better have a clean disk), keep the UEFI and the small system one (forget its denomination) if present .
If you have valuable datas, create a Linux live CD and boot from it , you should access your partitions.

How to delete it? Good thing I've backed up my personal files before this happened.

EDIT: Should I use bootrec.exe?

So the last resort is using a Linux Live CD, run Gparted, and format all the drives i mentioned earlier to NTFS or delete all of them and create new clean partitions.

maybe someone will come up with a better solutions but personally i am a format kind of guy (faster and no hassle ) :p

Thanks @Umbra. Luckily, my brother has a spare USB. Downloading Linux Mint now. What about Partition Wizard Bootable CD?
