Repairing Windows 7 on Samsung ultrabook

Hi all,

my Samsung Series 9 Ultrabook does not start properly. Windows 7 Professional boots, lets me log in, but this morning, the wireless network would not come up and although I could open Control Panel, everything after that was pretty much frozen.

I started the Samsung proprietary tool to repair Windows, which booted into an interface that looked very much like XP, and after that the situation got even worse. I now get only a black screen after the Windows logon and ctrl-alt-del will get me to a screen with a few shadows of menus, but no content.

I can boot into Safe Mode, with or without command prompt.
With command prompt, I can see all the disks, all the partitions.

I can backup all my files onto a usb stick and to a full reset, but I'd like to avoid that.

I have a USB stick with a Windows 7 Professional iso made into a bootable stick.

I have another bootable USB stick with a recovery disk made on another machine running Win7 Enterprise.

If possible, I would just like to repair the existing Windows installation. If that's not possible, I'm fine with a new install, but what happens to license codes etc?

Before I go and fry the system totally, what would be the course of action recommended by you Windows experts?

Please explain why and give me a bit of background. I'm no hardware or OS person.

Is this a purchased copy of Windows 7 or an OEM build?  Meaning with the OEM Build, there is usually a recovery partition.  If it is a purchased copy of Windows, you can start the system with the install copy of Windows and work from there.  You can download directly from Microsoft Windows 7 repair ISOs that you can burn to CD or DVD..

At any rate, it is good that you have your documents, etc. backed up.
Do you have any restore points that you can go back to?

Kdyer, it is an OEM build that came with the laptop. And yes, there is indeed a recovery partition. I can look at it for hours and will still not know what to do with it.

I can see the recovery partition from the command prompt  in safe mode. And then? I know I can hit F4 during boot and do a system recovery, but that will overwrite all my installed stuff, won't it? I'd like to keep my installed stuff. It will take a week to re-install all of that.

>> ... Work from there

Means what exactly?  Can I use a Win install disk to repair the system? I want to avoid a factory reset. If possible, I'd like to repair Windows and keep all my existing installed software intact.

>>  You can download directly from Microsoft Windows 7 repair ISOs that you can burn to CD or DVD..

From where exactly? Ad it's an ultra book. It does not have a DVD drive. USB is the only way.

As I said above, I am no OS expert. I need detailed instructions.

Dronethought, I tried recovery. There were only three restore points, the oldest from the Office update earlier this week.  I tried to restore to the oldest, selected it, clicked Next and then got a window with no content, no button to OK, and the restore could not be started.

boot from your Windows 7 USB stick, and run a repair :

but it can be you have hardware problems (bad disk drive, or ram) so i would first run the memtest86+ for ram, and the disk diag for your disk brand from UBCD (you can make an USB stick to boot it from - after you made the cd, so probably best majke it on a system with a cd drive)
Hardware diagnostic CD    UBCD
 i suggest the UBCD  to run some diags first - to be sure about the basics
go to the download page, scroll down to the mirror section, and  click on a mirror to start the download
Download the UBCD and make the cd   <<==on a WORKING PC, and boot the problem PC from it
Here 2 links, one to the general site, and a direct link to the download

since the downloaded file is an ISO file, you need to use an ISO burning tool
if you don't have that software, install cdburnerXP :

If you want also the Ram tested - run memtest86+ at least 1 full pass,  - you should have NO errors!
For disk Diagnostics run the disk diag for your disk brand (eg seagate diag for seagate drive)  from the HDD section -  long or advanced diag !  (runs at least for30 minutes)                        ultimate boot cd             download page

Instructions how to use Samsung Recovery.

Normally I would suggest a Repair Install (different from startup repair) but I have no experience whether it runs from a USB stick.
This should not affect personal data or installed programs.

@nobus, Thanks, that got me on the way. I found the relevant windows menu by hitting F8 during boot and then was able to get to a working system restore dialog and restore to an earlier point in time.

@jcimarron, I had used the Samsung tool in some flavour after the error first occurred, but it really messed up my system.

cheers, teylyn
