Nicom, remove HD and try to enter bios setup again to disable ahci mode.

[NicomUA]

I can't enter to BIOS setup. Always 2 lines on screen.

Even removing the hard disk?

Then you will need to open the case to find the cmos battery and remove it for a couple of minutes.

[NicomUA]

Yes. I already try this. Result are the same.
When HD in notebook and I hold Win+B on boot,notebook start beeping, HD led blinkibg and only first line showing. When it stop beeping, the second line are showing. I think he try to find HP_TOOL partition.

[NicomUA]

No. HP_tools partition didn't help.
