Partitioned primary default MBR on 500gb (now 465gb) HDD and X:drive is still there but won't boot up. I'm using a random disk with misc start files . anyway downloaded windows recovery media via my Android tablet copied raw "as is" compressed media to properly prepared 32gb flash drive, also recovery media of mfr with drivers and HDD says it's missing subsystem but these media are setup to run on systems without its system programs. Nothing is on C:\drive that I know of. Does anyone have any idea what subsystem it could be? Maybe Zip/unzip capabilities? Thank you lauraM. Oh sorry didn't mean to discuss my questions ..
