So... I'm confused. AnX suggests that InsydeH20 is the problem. I've found that XP has been PreInstalled.
Please tell me exactly HOW XP can be installed but 2K can't? Is there a particular reason, AnX?
I have found the Service Manual for the (made by Acer) E350. It indicates a D2D Recovery setting in the BIOS - TURN IT OFF and LEAVE IT OFF! It gives no indication of the settings for IDE Configuration, BUT I'm willing to bet that you can TURN OFF Sata-Mode.
Start from this post and read down a couple of posts. It appears that there IS a setting for turning AHCI off.
I'm not sure where, but it MUST exist! BTW, you WILL have to "wipe the disk" (not really wiped, but...) using "diskpart clean" on it to re-initiate the HDD. NOTICE! You have inducated FOUR PARTISIONS! I'm willing to bet that you DO HAVE THE STOCK OEM INSTALL ON IT!!! That, in and of itself, will cause you some headaches (ref. D2D notation above).
HERE is a notation about IDE-Mode by a guy that had Win7 Pr-Installed and "downgraded" to XP.
So... I don't get it?
edit - Here's the Support page -
It clearly indicates both (32-bit) Win7 and XP.
Both D2D and SATA Mode options should be right there on the MAIN screen.
Motherboard is "Acer LA-6311P NAV51"
