Another tid-bit in case you haven't resolved this yet. In the bios there is a setting for SATA relating to hdd's Change it from ACHI to IDE (sorry don't recall exact wording and is different with each bios).
I swap hardware all the time, usually dual core to i5 quad core, very few issues with Windows 7. From: [email protected] [mailto:[email protected]] On Behalf Of Jimmy Tran Sent: Wednesday, August 27, 2014 9:02 PM To: [email protected] Subject: [NTSysADM] move hdd with windows 7 on it Hi all, Got a dual core Pentium pc with windows 7 home on it. I cloned the hdd and installed it in a quad core i5 pc. It fails to boot and give the error "boot selection failed because required device is inaccessible" 0xc000000e. I obviously want to prevent from reinstalling the OS. Is the problem because I'm going from a dual to a quad core CPU? Does anyone know?
