Windows 7 can't start after updating BIOS on ASUS M5A97 R2.0

[POMMES95]

Hi everyone!

I have just updated my BIOS on ASUS M5A97 R2.0 with the latest update: 2603
(The last version of BIOS was under 2000)

Now windows 7 can't start, it begins but breaks down! So the boot is okay, AHCI mode is on, other devices are turned off, safe mode also begins but breaks down during loading and the system restarts everytime. BIOS works well, also the windows-repair service, it wants to find the problem but it can't solve it.

Windows is on SSD and worked well on it before the update.
I have tried the SFC, RAID mode, system backup but failed
My next step is trying to repair windows with USB.

If it does not work do I must reinstall the windows? What should I do? Please help me!
(and sorry for my english)

Boot into BIOS and set optimized defaults then check the memory speed & timings. Save settings and exit BIOS and see if that works for you?

I have tried it but nothing 🙁
I have met this problem on an Acer notebook, it was the same behaviour but without BIOS update, so I have thought at the beginning of this my only solution is reinstalling windows and I did it now too. So reinstallation has been happened but I must say windows works a bit better than without this BIOS update

You need to install all the MB drivers after a new windows installation. Also, should boot into BIOS and set it up correctly, like mentioned above.
