Problems with running windows? What do you mean? Did you set your SATA settings back to same as before? Probably AHCI needs set instead of IDE. You can flash back to other older version again now if you want, but be sure to load optimal settings once done, and then reset your SATA Settings again too.
Well, this backup has same issue
I will have to see about correcting, stock BIOS does not contain this problem (It's NVRAM Stored outside NVRAM area, duplicated MANY times, and with incorrect Volume revision values). Before I do anything I will find some other dumps from this same laptop and compare, maybe this is normal, but it shouldn't be!
*Edit - I compared to two different dumps from other same systems, they do not have this issue, so normally I would not feel comfortable editing this BIOS, but we can test a write back of your current backup and if all is OK then it should be fine. If you want to test that please use FPT and write back one of your FPT backups to the BIOS using the following command
FPTw.exe -bios -f backupbiosname.bin
^^ Change backupbiosname.bin to whatever the file name is that you're using. If that goes OK, without error we should be fine. If there is any error during the process stop and do no proceed, show me image of the error and command entered.
