Windows Technical Preview Installation Problem Legacy BIOS+MBR

anybody out there who gave a big round of applause for our most valued member arsen92 who brings it to the point ... mostly ... no .... all the time

 

Ah, a very important point that you forgot to mention!! I never use Minitool from within Windows OS. I always boot from DVD, and choose option #2, Boot to Safe Mode. So, yes, that could be why you got that message earlier from Minitool, and it refused to convert the drive to GPT.

So, boot from a DVD, and give it a shot. But like I said, one way or another, at some point in time, you'll have to delete partion C: and leave it Unallocated to do the Win10 TP install. I believe the reason you can boot with 8.1 and not with 10 is because 10 TP wants to be put on a GPT drive. When I installed to one of my laptops, it refused to install until I converted the disk to GPT. After that, it went like clockwork.

Another thing, I was going through some notes I had made when I repaired and upgraded another computer, and I found that I had to disable PXE OPROM to get an install done. You might consider trying to do that if you keep getting negative results. It's not going to hurt anything to disable it for a while.

Why do I get the feeling that you are being obtuse?

I believe it's just another example of what I said earlier, he/she has one way of doing something, while most others have another way of doing something. The important point to realize is the fact that many roads lead to the same place, and some people prefer one road over another.

Geez, now I'm being obtuse...

Because most people prefer convenient and fast GUIs over lengthy and time consuming command line interfaces.

 

actually, I don't believe Paul was being obtuse, rather pointing out that Arseny always has a useful and well placed post. MVP of MDL indeed

 

Try another hard disk, please. This is not about partition scheme problem any more. I think your hard disk is behaving funny.

 

In that case, I have learned something, and I recant my statement. It just seemed to me at the time that I read his post, that he was giving instructions and suggestions to someone who struggles to use even Rufus. I probably should have stood back, and looked at the big picture, that he was only attempting to teach the OP another method operand i.

Lesson learned.

Hey Abhishek, I just read something VERY interesting, that may help you out greatly!! Matter of fact, it might help out more people than just you. Here is a copy/paste of some information I found regarding installation of Windows 10 TP:



"Yes, I installed a UEFI upgrade of 8.1-10TP in-place right from the mounted .ISO in an 8.1 boot. Worked flawlessly. Then, just to try out a theory, I did it again, only this time it was a 10TP-10TP in-place *reinstall* right from the 10TP mounted .ISO... I wanted to confirm that I could do a "repair reinstall" of Win10 just like it works in Win8.1, and it works! No need for "Refresh" since the in-place "reinstall" preserves all of your personal files, programs & settings, unlike Refresh (but exactly like an in-place upgrade.) The end result here is exactly what happens in WinXP when you do a "repair reinstall," except you don't need to boot from the install media like we had to in XP to do a repair reinstall.

It's a terrific feature of both 8.1 & 10TP, and Microsoft should be more forthcoming about the "other use" for running an in-place upgrade right from the target boot . IMO, "refresh or reset" should only be used when your Windows install is so broken that an in-place reinstall of the OS just won't work."




Now to me, that's the way to go. I wish I had known about this when I did my last install of Windows 10 TP. I wouldn't have had to re-install my favorite 3rd party programs, none of that. Of course, there would probably have been a couple of programs that didn't work anymore, but all in all, this sounds like the way to go.

So, if when you come back to the forum here, and if you've not been able to install Win10 yet, why not give this method a try? I think it will work fine for your situation, don't you??

sorry to read about your problems. don't know if you've had any luck, but here are my suggestions, for what they're worth. there are so many variables involved here that without having the physical computer or teamviewer it's almost impossible to come up with a 100% fix. i have this problem all the time with people trying to fix their computers over the phone, success of fixes depends on amount of knowledge. some are easier than others. first i would google the error code you got. plenty of examples going back to 8.1. next i would disable the pxe oprom, from what i read it is only needed for a network boot. next i would disable or uninstall any third party security apps ( antivirus, cleaners, firewalls, etc. ) that can be reinstalled after a successful upgrade. for now stick with the mbr. i wouldn't do a convert to gpt unless you have a backup of all your important data. as far as the HD problem suggested, it's possible but i doubt it, unless you have a virus or malware problem. also try installing from a DVD instead of a thumbdrive. some are known to have problems. these are only a few suggestions. remember this is only a Preview, so why go through the hassle of backing up and using it as a primary OS. if anything happens down the road with a bad update or such you may loose everything. gl in your quest. hope all works out.

 

You can also change to gpt partitioning by adding the convert gpt command in diskpart:

Code:

list disk
select disk 3
clean
convert gpt
create partition primary
format fs=fat32 quick label="Some Drive Label"
assign
exit

 

@ Abhishek Anand

You are having a hardware problem. Don't use the existing Windows 8.1 running on your system to define this case. I have come across a situation where existing Windows work with little lags but failed to accept clean installation only to find out that the hard disk is faulty.

From my little understanding, it is time to look into your RAM and hard disk. I think all avenues to forestall your Windows 10 Technical Preview installation have been exhausted. It is now time to have a look into the hardware.

 

Welcome back, and glad to hear your broadband is normal again! Basically, yes, you are correct. Don't even use the USB drive at all, just mount the .iso image from within Windows 8.1, then go the the mounted drive, and open it with Windows Explorer and click on setup.exe. That is what the other fellow was saying, that it worked just fine from within Win8.1 while it was active, and it saved his programs and settings.

The last part of his information was just a test he did to see if he could do the same thing, once he had Win10 TP up and running, and he said it worked fine also. Better than using Refresh or Restore, because you keep your programs and settings.

So, now that you have Windows 8.1 back up and running, don't do anything to the bios, and from within the 8.1 OS just mount the TP .iso file, navigate to it, and double click on setup.exe. See if you get the same results that he did.

You have tried a LOT of other things, this might just work for you!

I must have missed that. It was my understanding that you have been using a USB flash drive each and every time you attempted an install of TP. Am I wrong about that? Are you saying you actually did just mount the .iso file from within the 8.1 OS, then double clicked on setup.exe on that mounted drive. No USB flash drive used at all when you tried that?

 

Try installing using only the mounted .iso file first. IF that doesn't work, try to disable Secure Boot from within your bios settings, then try to install using the .iso file again. That might do the trick.
