Windows 7 won't boot after new motherboard but can get to BIOS?

[CallumCJ]

Hi I need some help asap, I just swapped out my old motherboard since it was quite rubbish (really old packard bell m-atx board) for a brand new ASrock P5B-DE motherboard.

However after installing the board and plugging everything back in exactly where it came from on the old board, the PC cant boot into windows 7 64bit. I've tried the repair option and it doesn't work.

I've tried disabling and enabling various options in the BIOS. Also tried removing the memory and only using 1 stick then tried both sticks in different slots and that hasn't changed anything.

I've tried inserting my Win7 CD but it doesn't seem to boot from the DVD drive (will keep trying to see if it can).

System specs are:

Intel core 2 Quad Q6600 @ 2.4GHz (using Freezer Pro7 CPU cooler)
Samsung DDR2 800mhz Ram (2GB x 2)
160GB 7200RPM Hitachi HDD
ATI (XFX) 5830 1GB GPU
Zalman 500W PSU


my next point of call (thanks to some google searching) is to try a lower end GPU as i've still got my Nvidia GTS 250 and doesn't use any external power from the PSU.

Any help would be appreciated as I need the computer up and running ASAP

Cheers

(P.S. I'm not overly bothered about doing a clean install as i recently did one anyway and I haven't had a huge amount of programs installed on the pc since then. But if I can fix this without a clean install that would be preferable)

Hello,

I just wanted to post a solution that worked for me as it was really a quick fix. I started doing dism solution from all the threads and then accidentaly red a solution that would save my life. [/b] I just changed BIOS storage settings from AHCI to IDE. [/b]This way i could load up Windows and install my new mobo drivers.

Hope this helps!

The Dowd&Associates article ( http://www.dowdandassociates.com/blog/content/howto-repair-windows-7-install-after-replacing-motherboard/ ) mentioned above is a great one. BUT, before you go through all those steps try this one first.

Enter Bios and go to the drive configuration screen.
If the setting is for AHCI, change it to IDE and vice versa.
Save and exit. Restart computer is the exit doesn't automatically.

You should see that it goes past the point where the bsod and reboot took place fairly quickly. Then wait as it will take a while for windows to churn through the changes and get to your desktop. Then you can load the new drivers from the DVD.

This, of course, doesn't work every time but it does often enough to make it worthwhile to try it. As I understand it, if your old motherboard ran your hard discs as IDE, you have to set the new mobo to IDE to get your hard drives to be recognized. If it comes pre-configured to AHCI, your BSOD is telling you no op system is found. (Which makes sense if the hard drive isn't recognized.) The reverse is true also; if your old board ran AHCI and its preset to IDE again your drive won't be recognized, blah blah!

OF course, if you get the BSOD and an immediate restart, go ahead with the Dowd&Assoc. article AFTER you change the BIOS back to the original setting.

I just wanted to say thank you changing the drive config worked for me, I was experiencing pretty much the same problem as OP, My old mobo died and i replaced with an upgraded version (Gigabyte -X58A-UD3R to Gigabyte EX58-UD5) I missed the different difaults in the bios and was tearing my hair out for days. I shouldn't have missed that I feel rather stupid, anyway thanks.

Thanks. My first successful solution post, that I know about at least. I think I'll have this framed!
Seriously, I appreciate your comment.

The AHCI/IDE bios change worked for me at the 11th hour just when I was about to reformat my hard drive and lose everything. May you live forever, Dave!

I just changed out a motherboard for a breadboard system on my bench. I've been fighting for 2 hours to get it to boot after a big upgrade. I went from an old dual core Intel CPU and motherboard to a Z99 with I7-5820 CPU. I used the recommendation to change SATA type to IDE rather than AHCI and on the next boot it started Win 7. It then went into a configuration process and I will do a cleanup after it is running. The new parts are actually to replace my personal system's CPU and MB but I wanted to run some tests on this first. Thanks for those suggesting this option. I should have thought of it myself but reading it here kicked my memory.

Please guys who are asking for help, start your own thread. Do not jump in on an existing thread, it's bad practice as it creates confusion and makes threads way longer than they otherwise would be.
