Dvd not readable in win 7

[spex]

I used my sata dvd drive the other day to recover my vista install which had gone after win7 installation, it failed to find it. Today i was trying bf2 in win7 which failed so i uninstalled core and bf2 and went back to try and rescue my vista but found my disk is unrecogoniseable in explorer, only options on right click are format and eject . I went into my bios and set cd to boot and the first boot from cd line pops up but then it skips straight to booting win7. The win7 instalation is only a few days old so very little is installed. Drive shows up as cdrom in device manager but wont populate and no upper and lower filters are visible in regedit

Just tried booting a ubuntoo usb with no success, boot ignored "boot others no" and went into windows7, double clicking dvd in my computer causes eject to operate. My drive doesnt show in explorer but does in MyComp as a dvdrw
