All this is about a PC with Vista 32Bits on it.
An Asus laptop with single HDD in it - it is no SSD.
During booting the BIOS does not offer the ctlr+I option nor it presents "Intel Matrix Storage Manager Option ROM"
for me that's a sign that option ROM is not present on this PC.
However, the Matrix Storage Manager software was installed all the time.
So, I assume it was installed in order to have the hdd runs in AHCI mode.
No RAID array exists. Backup of whole system was done few months ago.
Recently the software Intel Matrix Storage Manager was accidently removed from system by user.
Unfortunately it was removed inclusively host controller drivers.
As result the system does not boot any more.
Taking this situation, is new installation of whole system, inclusively installing all used software,
performing all personalization, restoring all user data the only one possible way to recover?
Or, is it perhaps possible to recover by repairing some files/folders by recreating missing items
upon attaching this hdd to other working system?
If yes, how will be the procedure?
Nobody on Intel support forum was able to give answer to above questions.
