Hi I reinstalled windows 8.1 on my Samsung NP530U3C-A10EE. And now the problem this that I can't boot it without usb stick that contains windows installation files. I can boot up windows and remove the usb stick evertything is working perfectly, but if I try to boot up win without usb, it gives error "Operating system not found. Press CTRL+ALT+DEL to restart". VOLUME C:\ is one where windows are installed (SSD), System Reserved is the system partition that windows create automaticaly (SSD), volumes D:\ and F:\ are my hdd volumes D:\ is empty & F:\ is stored with my personal files (photos, music etc.)

P.S if i make C:\ active I can't boot up even with usb stick plugged in...


Maybe someone knows the solution? Thanks for responses.

You can try from Admin command prompt:
  1. diskpart -> select disk 0 -> select par 1 -> inactive -> exit
  2. bcdboot C:\Windows
  3. shutdown
  4. swap the cables between disk 0 and disk 1. (Make your Windows to be disk 0)
  5. From BIOS, set boot priority to this disk 0
  6. Reboot without the USB connected.

Hope this helps !!!

I managed to do that windows would be recognised and change the boot place to the right one. But main problem still is that I cant boot from ssd because it is not shown in BIOS. Any suggestions? @topgundcp I dont want to make any changes with hardware because the pc isnt mine and I dont want to break it completely

A 24 GB SSD is very small for an OS install. Is that device an mSATA which came with the computer?

According to your Disk Management picture, the system is booting to the mSATA. Maybe there is something still on the Flash Drive it needs to complete the boot.

If you went back to the Hard Drive, because of all the active partitions, it may still be configured incorrectly, or it may still be booting to the mSATA. Another Disk Management picture might be helpful.

Physically disconnect the other HD drive.
Make the Windows 8 HD, disk0 & first HD boot in BIOS.Also connected to the first Sata port on the MOBO.

than do a Start up Repair IF NEEDED.

Note: You may need to do startup repair 3 to 4 times.

When Windows is booting OK, Reconnect the other HD drive, as Disk1.


than
Mark the all other HD Drives INACTIVE
