Abit IP35 Dark Rider - double boots problem under newest BIOS

Hello,

I got Abit IP35 Dark Rider, it comes with the same BIOS version as IP35-E.
I changed processor, now it is Xeon E5430 E0. I used the latest unofficial modded BIOS ver. 18 (E0 support). But one wise guy from Taiwan added microcodes for 45nm to clean ver. 17 one more time (see attachment).

It does not matter, no change at all. (In one case on last original BIOS, in CPU settings there was no virtualization nor EIST support)

All the time computer starts with dual boots without cause. After restart, it also happens. I cant install Win7, there was suggestion the mobo is too old, but under E7200 my SSD Plextor has worked under AHCI mode.

There were no dualboots under E7200, only after OC once when I have changed settings.

I am exhausted seeking for help. There is another ATA drive there, I could lost it someday with these crazy booting.

Thanks!
