In some cases (SCSI HBAs), the geometry specified in the image will definitely be ignored. With IDE, it shouldn't be. Why not attach the VBox.log file which would unambiguously show what's really going on?kpv wrote:I have also tried to boot the very same .vmdk/.dd disk images under Virtualbox (4.2.18), without success ("Missing Operating System"). Apparently VBox disregards the CHS geometry specified in the .vmdk files.
We accept patchesAs others have requested in related reports at the bug-tracking database, it would be great if VBox would allow advanced users to manually specify CHS disk geometry.
