Finally I installed in ide mode then with this batch (executed in booted Windows xp IDE MODE) and copying the ahcix86.sys to C:\Windows\System32\drivers i was able to change to AHCI and boot.
@echo off
reg add "HKLM\SYSTEM\CurrentControlSet\Services\ahcix86" /f
reg add "HKLM\SYSTEM\CurrentControlSet\Services\ahcix86\Enum" /f
reg add "HKLM\SYSTEM\CurrentControlSet\Services\ahcix86" /v Type /t REG_DWORD /d 1 /f
reg add "HKLM\SYSTEM\CurrentControlSet\Services\ahcix86" /v Start /t REG_DWORD /d 0 /f

reg add "HKLM\SYSTEM\CurrentControlSet\Services\ahcix86" /v ErrorControl /t REG_DWORD /d 1 /f
reg add "HKLM\SYSTEM\CurrentControlSet\Services\ahcix86" /v ImagePath /t REG_SZ /d "system32\drivers\ahcix86.sys" /f
reg add "HKLM\SYSTEM\CurrentControlSet\Services\ahcix86" /v tag /t REG_DWORD /d 4 /f
reg add "HKLM\SYSTEM\CurrentControlSet\Control\CriticalDeviceDatabase\PCI#VEN_1022&DEV_7801&CC_0106" /v Service /t REG_SZ /d "ahcix86" /f
reg add "HKLM\SYSTEM\CurrentControlSet\Control\CriticalDeviceDatabase\PCI#VEN_1022&DEV_7801&CC_0106" /v ClassGUID /t REG_SZ /d "{4D36E97B-E325-11CE-BFC1-08002BE10318}" /f

If you need to change your drive to AHCI, change the reg key \PCI#VEN_1022&DEV_7801&CC_0106" by your hardware id.
And if you have another hardware you can change the ahcix86.sys by your sys file and the hardware id key \PCI#VEN_1022&DEV_7801&CC_0106" by your hardware id.
