Windows 10 upgrade on Win 7 Pro hanged progress, cannot load Win 7 Pro

Hi all. My first post here.



I tried to upgrade my Windows Pro x64 system via the internet method not the Media Creation Tool via USB. The upgrade hung up at 17% for 4 hours, so I hit restart.



Now, I just want Win 7 Pro back (I own the disk) x64 and this M5A99X evo Asus MoBo is a EUFI. I cannot find anywhere to change it to a Legacy.


I pulled everything off the MoBo, reset CMOS, shorted the jumpers, took the battery out, pressed the power button for 30 sec, RAM all out, and the graphics card. This machine worked flawlessly - I built it in 2012 and put it away and have been using it sparingly for 6 mos. I have 16 gig w/ 500 gig SATA drive all clean.


My issue: I tried to figure out how to get Windows 7 Pro x64 back on, I put the disk in the DVD drive and changed the boot order and it hangs in one second at the start up logo.



Getting into SAFE MODE is tricky, as I forget if I need to press F8 or F12. When it comes up I choose SafeMode and it hangs after trying to unload a bunch of files.


I have had the BSOD with Ox000000... code.



I wonder, did the upgrade mess up my BIOS and put it as a GPT and I need EUFI or Legacy?


I am only going to keep two 500 gig hard drives to use with a Focusrite and Ableton products for music recording. This system runs normal at 2.8 GHz and up to 3250.


May I ask anyone for help please, I have been at this machine for 2 days for about 6 to 8 hours reading on the internet, Facebook and there is some possible results but they did not seem to work. I think my BIOS is ruined. When I reset the CMOS and take the battery out, the America Megatrends screen comes up telling me to press F1 to I think the BIOS EUFI screen.


I have the two hard drives formatted but I am only trying to put one on for now and when I try to load windows from disk, a screen comes up telling me to disable or disconnect any device that does not have a Bootable File!


I thank you in advance to any help on this.


PS: could I just buy another MoBo and just put the RAM and GPU and CPU on it and it would run...?

Welcome to the forum. Its hard to say not being able to see the pc. did you leave more than on drive in when doing the update as that tends to screw it as it put files on other drives you upgrade or or install with just one drive.


If you have cleared the bios all settings will be default and need resetting.


Bios should be set to secure boot uefi if you have it with no details of your system we dont know.


Your best option is to download the 10 iso create a usb drive and boot from that and do an install.

Sorry to hear your Windows 10 upgrade did not turn out right. I am not sure from what you wrote, what stage of the installation failed. It might be that the Windows 7 installation is still there.

This is not the correct way to go about the problem you have.
Did you put the jumper back onto the correct pins? You now need to check all the wiring is correct. Consult the manual if necessary. Here is a link to the ASUS manual. Download for English.
If you are still experiencing problems after that, then temporarily disconnect the HDD from the computer, and try to boot to BIOS or boot to DVD.
If the computer is still resetting, then you might want to check the AI tweaker, and turn that off, as that can stress some hardwares.
The AI tweaker is in the ADVANCED Menu. To reach the Advanced menu, enter BIOS and click on Advanced Menu/Exit button on top-right of screen.
There is no UEFI/Legacy BIOS setting on that motherboard. That is not your problem. Windows 7 can be installed on UEFI UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with

Hello Samuria!


I would have to try and reset the BIOS maybe!?!


Which I am not sure how to do that - would I flash it?



I did try the Media Creation Tool and it will not even read the USB stick, nor my DVD ROM/CD...well it does when I try to reload Windows 7 Pro x64, but I think the attempt on putting Windows 10 on the system that got hung up, changed my BIOS as a Gxx sorry forget the Windows 10 thing that allows for bigger drives than 2 TB... But need to change it back to EUFI...there is another reply below and I will try to put as much as you guys need I have written down what all the hardware is and what happened...thank you Samurai

Hello! I will try to answer in order and thank you kindly for your help!


Yes, I put the jumper back to pins 1-2 (jumper to 2-3 when resetting of course!!!), I had all hard ware off the board, even the battery.



You are right I believe I have to go in and get this BIOS back to factory?! or EUFI as I think it is stuck in GPT from the Upgrade attempt from the MS site online (not the USB method!!).


I have the manual and downloaded too to consult and I have the disk for Windows 7 Pro (my licence) and the MoBo's CD. This is a new system that was not used until now - so New/ Old Stock per se.


I have tried booting without the HDD but I can do that again as it is blank (I formatted the HDD off my Windows 7 Home Premium desktop to 'unallocated' and I am sure it was FAT32 or what it NTFS that I would have to reformat would I?


All wires and connections are all in place.



But I will go in and do what you suggested...


What I will do is pull all components out again, take the battery out, then jumper the CMOS with the computer switch off and unplugged and press the Power Button to drain the residual energy left to drain the caps...


Then,


I will keep the HDD unplugged > Go into BIOS and turn off AI Tweaker > and have the system Boot to CD/DVD first (of course!!) and put the Windows 7 Pro disk in while I boot!?!


Maybe I will format the HDD again using my other Windows 7 Home Premium desktop!



I truly appreciate the help, I've lost so much sleep over this trying to fix something I am new too as it's been 8 years (2012 since I built this) but never ran into where the GPT will override the EUFI - but makes sense as it is to help accept larger drives I get that but for me not important...take care and I will come back on and tell you how it went.

It is a no go!


There is no way to disable the Ai Tweaker that I can see, there is a choice for Manual, Auto and DOHP. So, I put it back to Manual (the way it was when I built it) I had it on Auto thinking it would be more efficient/balanced for speed and such.


I formatted the HDD with my Windows 7 Home Premium desktop and put a label and drive letter on it as I did not have that before, the drive was just called 'unallocated' with the Black Line in Disk Management.


So, I Booted the Asus System without the HDD plugged in, and I did yank all the components out again (battery out, CMOS pins shorted and put back to 1-2 position).


I went in and made sure the Boot sequence was where the CD drive would be the primary boot device. I plugged in the HDD after I set Ai Tweaker to manual and put the Pro 7 disk in.



It read the disk but then hung up on me again. I took photos as I do not own the expensive iPhone to do a movie (I still have a land line!!) LOL. I admit I am behind the technology for sure, but I can understand most jargon if need be on here. It is very disappointing for this old guy to not be able to fix this one especially when it was fine...just thought to give in to Windows and get Version 10.


Before I put up the photos in order of the BIOS a person on Facebook has stated this:


Can you not plus in the SSD/HDD into the working computer and using disk management or command prompt, convert it from GPT to MBR? Then try USB boot for windows 10 again? Also how is the USB drive formatted (might have to try the opposite of what it is currently formatted as).


I can either buy on Kijiji someone's windows 10 system for $350 CAD I just hate buying used you never know what you are getting...my concern is if that system (whatever it maybe) will read any of these drives I have?


Or if I can ask if you know of a good place in Canada to buy a bare bones system without the case and psu. Since this system is new but Old '2012' I would just part it out for $2! LOL Hate to see this go really.



I was going to run a interface like Focusrite 2i2 and Ableton software Live 10 Lite and/or Cubase LE5. they require 8 gigs of ram and 500 gig HDD is fine...


I apologize for wasting anyone's time, I am not very rich, and I am just trying to fix my error in attempting to better my system with the great Windows 10!!!


Take care and hope we all overcome the worldly dilemma!

Those Photos, the first one is the frozen screen - the others are the navigation and what is in the BIOS and what they are set at! The others did not load it just was the BIOS settings mostly default except Ai Tweaker on Manual this time...I downloaded the Media Tool again from my Windows 10 laptop and I will try putting it on a USB at the back as a guy on FB is saying it worked for him??!!!

M5A99X Evo ver. 1.0 has a Legacy choice in BIOS!!


I tried the Media Creation Tool and put the USB on a back USB rather than the front (facebook person said it ran for him) lucky him.


I ran for a bit but no go.



Also, Win 7 Pro disk is a no go...they all freeze.



I tried both Windows 10 USB Media Creation Tool and Win 7 Pro disk without the HDD and again - freezes.


As far as getting into DOS, it is called FreeDOS. I do not know how to write to where I try to format the drive from DOS...like Format C:, but what switches do I use? I am not certain if any of the Windows 10 or Window 7 Pro loaded on my HDD - that is why I was inquiring if I have to format it...I can do that with my older machine 2009 x32 Windows Home Premium...


Upon making changes I ran into a: BootMGR missing and a few STOP CODES: WHEA UNCORRECABLE ERROR, I got SYSTEM THREAD XXXXX, and a MACHINE CHECK EXCEPTION. One might be cause by enabling EHCI xxxx, the other was changing Legacy support for USB (if detected) set on Enable rather than on Auto? But, I am no pro that is for sure.



How do you guys get a MoBo back to specs from the factory?


I do have the MoBo disk, but how can I load the drivers that might set this machine back to 'normal' as I am not certain if it is stuck in EUFI or GPT. Since the Windows Media Creation Tool has Windows 10 is that not GPT and if this machine is stuck in GPT is should load?!?


And if EUFI, then Windows 7 Pro?


What a last three nights...TIA everyone!

Keep the AI tweaker on manual setting
Windows 10 creates two partitions. One of the partitions is a systems reserved partition that does not get a drive letter assigned. If you are re-installing OS on that HDD, then it is important to erase the system reserved partition as well, before you start an OS re-install.
Make sure the computer is set to boot into CD as primary device.

Go into BIOS, you should see a list of connected devices. In BIOS go into Advanced Tab, and check SATA configuration. Your HDD and CD drive should be listed. It will say "Not Present" if none connected.

Hey iko22!!!


LOL, I am still at it tonight! 3 am now here! I wonder if this MoBo is compatible with Windows 10?


Post #8

Is Legacy EFI what allows Windows 7?



Post #7
Yep, they are all there! LOL


Post #6
Okay, I will put it back to manual setting. I did have this set to that before I started getting desperate! LOL


I will cut and paste you reply to follow for later today, I need to go to sleep as I am getting worn down, but I do not like to give up at least not yet!


The guy on FB tells me my HDD is dead...LOL...that's why it runs and formats...just a waste of time on FB...I am new to the social media pretty much...I don't even know how to check that I got a reply unless it comes through the email here. Lots to learn.


I read up on this Rufus 3.8, if I have that right, it is for systems where the Media install does not work? I did not understand how to employ it as there is no HDD or the HDD is not accessible yet.


I managed to do a .iso of my licensed Windows 7 Pro x64 disc as I thought maybe putting that in instead of the CD, just in case it may work...but then again the Media win 10 did not.






What would happen if I somehow had a HDD with Windows on it and booted this system, I wonder if it would work?!






The other unknown is; can I use the Windows Pro disk in my Windows 7 Home Premium desktop and load Windows 7 Pro on the HDD that I am trying to use for the other desktop? Or for that matter I have a 3 license Home Edition and wonder if I can put it on this HDD and if it works, just upgrade?




Is this machine stuck in GPT? Is that why I cannot load the USB stick with the Media Creation Tool or the CD ROM as both OS's freeze up during installation....?




Thank you once again - I thank you kindly as always - the battle continues later tonight/today!!


Cheers iko22
