My laptop keeps crashing on boot after clean Windows 7 install. Ok, here is the story, and some fact.

Computer: Samsung NP900X3C-A04HK (256GB SSD, 8GB RAM) OS to install: Windows 7 Ultimate SP1 (not from Samsung, own fresh Win)

I purchased this laptop about a year ago, never booted it into the Windows Home that was installed on it, installed directly Ubuntu on the machine. Full disc encryption was the selected install, so of course it wiped the complete disc (including Samsung Recovery Partition).

After some time, I felt like going back to Windows, as Windows 7 is actually quite nice. So I went to buy a fresh Windows 7Ultimate with SP1.

Now to the tricky part. Windows installs perfectly, and after installing all Windows updates, drivers from Samsung, software I need, it is time for shutting it down and go to bed. Starting it up again, and it is not booting, these are the type of errors I have gotten so far (fresh installed it more then a dozen times now, and tried different suggestions from threads on the net). Windows failed to start...

Status: 0xc000000f Info: The boot selection failed because a required device is inaccessible.

File: /boot/bcd Status: 0xc000000f Info: an error occurred while attempting to read the boot configuration data.

And some other errors, not all the same. Not memory of this.

I have run different disc checks, and all says my SSD is in perfect shape.

Note: Soft reboots from Windows menu works, never gets corrupted. But if I Shutdown and then start it up again, this is when it happens.

Can someone help me not get back to Ubunut? What can be the cause, and how can it be fixed so I do not get there problems again?

Do you have another boot CD? – cutrightjm Nov 22 '12 at 21:51
Only the Win 7 install (on a usb stick)... Do you mean as a recovery cd? I want to solve so that the "corruption" doesn't happen again, I don't want to fix the boot for each time I shut down the machine :) – pjotr_dolphin Nov 22 '12 at 21:58
When clean installing W7, delete all old partitions first, then click next to install W7, Do Not pre-format the disk. – Moab Nov 22 '12 at 22:06
Moab, I did that, no pre-format of the disk. – pjotr_dolphin Nov 22 '12 at 22:08
Typo in model number, it should be NP900X3C-A04HK. – pjotr_dolphin Nov 22 '12 at 22:09

The answer is: do not be stupid and ignorant...

I downloaded the wrong drivers, I downloaded for NP900X3C-A04HK, but I should have downloaded for NP900X3A-A04HK.

After upgrading of all drivers, all went well... Have rebooted, shutdown, sleep, etc, and no problems anymore.

The problem was probably that the chipset/motherboard drivers were not compatible, or buggy (older version)...

I agree with your fix. It was possible that it had something to do with the drivers, but more or less there could have been some other issues. I'd like to point out that Windows 7 Ultimate is designed more for computers that have at least 16 GB's of RAM. – JustinD Nov 26 '12 at 18:33
