What about F12? Did you see my earlier post?

Sorry Greg, I meant to say on my previous post that F12 didn't work. When I press it nothing happens and Windows 7 starts booting normally.

Then I would set flash stick to boot first in BIOS setup, when the install reboots unplug it and keep it unplugged unless it prompts to reinsert it.

That's exactly what I do.
I choose to boot from USB device, install Windows 8 and then when it restarts I remove the USB flash disk.
I remove it because if I don't the whole Windows 8 installer starts again like I never installed it before.

David, thank you for the link. I had the same first two settings as you in the drill-down snip, but I couldn't find a match to Pedro's Ultra #.

1a.) About the screenshots you asked, do you want me to take screenshots from my BIOS?
1.) I'm leaning towards; you do not have Win8 installed properly. The quickness near the end of the Win8 in-stall that you explained earlier has me concerned about the completeness of the in-stall.

  • Open an elevated CMD prompt.
  • The prompt line should read C:\Windows\system32>_
  • At the end of the blinking cursor type in bcdedit, touch Enter or return.
  • You should see something like this:

Use your snipping tool to crop, save, and post in your next reply, I save mine in a 640x480 .jpeg size. You can also go up to the tiny CMD prompt in the upper left corner; right click >edit >copy >into notepad, then post that into a code box, its the # in the menu bar of this Reply Editor.

Note   Note
I see there has been further instruction from Greg with a re-install. Try that, but I would still like to see a screenshot of the bcdedit, whether the re-install was successful or not.

If it isn't I would suspect:
  • Something wrong with the USB Stick.
  • Something wrong with the installation/procedures process.
  • You may have to go into your BIOS and turn the UEFI feature on and then try a re-install.

About the UEFI or MBR BIOS, I don't know what you mean sorry. Can you please explain?
The interface defined by the EFI specification includes data tables that contain platform information, and boot and runtime services that are available to the OS loader and OS. UEFI firmware provides several technical advantages over a traditional BIOS system:[11]
  • Ability to boot from large disks (over 2 TiB) with a GUID Partition Table, GPT.[12][13]
  • CPU-independent architecture[12]
  • CPU-independent drivers[12]
  • Flexible pre-OS environment, including network capability
  • Modular design

Pedro, but also for the other responders of this thread.

I came across this interesting thread while researching Samsung's HDD/iSSD configurations: GUIDE: How to install Windows 7 or 8 via USB on NP700Z*, although, the title may be a little misleading it may work for your Series5 NP530U3C
This guide may work with other Samsung Series 3, 5, 7, and 9 laptops with iSSD/ExpressCache as well. Give it a try and report back. I will add to this list:

- NP700Z5C-S01US
- NP530U3C

Source from the Guide Link above.
There are also three alternative methods.

David suggested earlier that the usual method when installing a new OS, is the user (Pedro) should disconnect any drives that do not have the original boot or operating systems, and it should be the one you want the new OS installed to.

Pedro's reply was:

After reading up on Samsung's iSSD configuration I understand why. It is designed to be an integrated and hidden adjunct to the HDD and it ends up getting in the way of any "clean" re-install because of the System Reserve.
There are no problems if the user needs to use Samsung's Recovery/Restore Functions because it is designed to do that seamlessly.

So Pedro
, I would suggest you go over the methods in the Guide for installing Win8. You will see after reading though it that you are experiencing some of the symptoms described in the Guide i.e. Endless loops, and perceived problems with the USB Drive.

There is so much there I felt it would be better if I sent you there rather than to try and explain it here and have a step lost in the translation.
Take your time and absorb what is in the Guide and the responses from the users in that Forum, from what I see the suggestions of the other users are incorporated into the three alternative methods and it would help if you printed out the methods when you are ready to try one of them.

GUIDE: How to install Windows 7 or 8 via USB on NP700Z*

Please keep us apprised of your progress. If this works I'd still be interested in a bcdedit report.

It is a moot point now, but thank you for adding those UEFI Tutorials after I suggested turning it on to try the install in my last post.
I realized after the fact that if I'm going to suggest something, I should have added guidance.

Hey guys, sorry for the delay, it's been a long weekend.
As for installing it through Windows, it only gives me the option of wiping the whole local drive and install Windows 8. It doesn't let me choose the partition


As for your #35 post, here is the print screen:

As for your #36 post, I'm going to read the guide right now and I'll give some news after I read it.

EDIT: Well I read it and there's just one thing - The guide is for windows 8 install if you want windows 8 as your only installation. This is a problem because they tell me to format my iSSD and if I do that, it might cause trouble with my Windows 7 installation so I can't do that

EDIT2: Tried installing with UEFI Bios on and no good. Just a FYI :)

These are my suggestions for your joint consideration:

Unplug or disable all other HD's and peripherals except the target HD, reset the BIOS to defaults, enable Legacy BIOS or CSM, boot the installer, at first screen press Shift + F10 to Open A command Line, wipe the HD and format an Active Primary partition for Win7 as shown in Step 2.2 of SSD - HDD Optimize for Windows Reinstallation.

Close the CMD box, Install Win7, then Win8 in space you leave for it.

Afterwards we can help you move the paging and Hibernation file to the SSD. Unless Samsung can help you include it it likely will only continue to block install otherwise.

Another idea is to install either OS to the SSD which we have helped others do, by wiping and then partitioning it. There would only be enough room for the OS and your programs, but you can keep your files on the other OS linked via Libraries. When users asked us to help them do this several times before it seemed wild at first but all were happy with it.

Finally Samsung must have a Recovery solution which would set it back to Factory condition after which we could try to shrink C to add the Dual Boot, if you think changes which have been made are blocking progress. Surely the SSD is not in its proper configuration now.

Thanks Greg !
Well after all this trouble I'm ready to give up. I think I'm probably better off installing my Windows 8 in my Desktop computer.
I spent all Sunday searching online for this and the only people that made it possible made it using Hirens Boot, where they kept moving files between SSD and HDD to make it work.

So my conclusion is that Samsung messed up this laptop when they didn't think about this kind of situation (On Ubuntu forums you can see a lot of people complaining also about Dual Boot on this computer).

Well, anyways, before giving up I'm going to call Samsung and ask if they have a tool or any advice on how to do this and I'll let you know when I have the answer. If after that the problem continues, I think I'll just give up

I was hoping we could do as you suggested, and there should be a way to disconnect the iSSD from the HDD, but Pedro mentioned earlier that he was informed by the Samsung rep that he couldn't physically do that, and I also got the impression that it would void Pedro's warranty. Post #7

The recovery partition is on the HHD as an unmarked partition. Post #4


I apologize, that this isn't working out for you. When I first read the GUIDE I thought maybe we could put win8 in your D:\drive, but after reading more, I can understand your hesitation.

I believe Samsung's mindset about the drives was to give the Ultra better response time in returning to the desktop, and agree they were a little narrow minded in this configuration, but that doesn't help you and all the other users that desire a multi-boot system.
It'd be a little tight, and you might have to change some partition sizes, but the room is there.

Thank you for the BCEDIT screenshot. Oops! I mean bcdedit.

Please let us know the verdict after the Samsung call.
