We are facing an issue with Dell Vostro V3400 & Dell Latitude E4310 laptops. After running EEPC 5.2.5. setup at next restart it gives error "Operating System not found"
HDD access mode has been selected to ATA.
OS - Win XP SP3
No PBA is coming.
I think you will find the current version works fine. There were a number of changes to support some "special" features of the dells between 5.2.5 and 5.2.8
Make sure also you are not using any of the compatibility options, they are not needed (always enable USB, safe mbr, for example)
