More Information

Turn off System Restore corresponds to DisableSR registry value. With this Policy is turned ON, the System Restore tab may be missing in My Computer Properties. Also, when you run System Restore (rstrui.exe), you receive this message:

System Restore has been turned off by group policy. To turn on System Restore, contact your domain Administrator.

Turn off Configuration corresponds to DisableConfig registry value. With this Policy turned ON, the System Restore tab will remain displayed but the user cannot configure the SR options. It reads disabled by Group Policy.

Go to the registry and delete the lower and "upperfilters"for the CD/DVD drive option. you can access it by going to this option. REGEDIT >> HKEY Local Machine >> System >> CurrentControlSet >> Control >> Class >> Select for the option which is the first {4D36.....}. After deleting the upper/lowerfilters, close the Registry Editor and restart the laptop. Then there try inserting a blank disc or any disc. Thank you.

try to run system restore. but if it doesnt work. check the functionality of the drive in safe mode (by pressing f8 when the computer turns on, dont wait for the windows logo to come up, you need to press f8 before the windows logo screen) try to explore whats on the disk and if it works. delete upper and lower filter by following the path. click start, click run, type regedit, hkey local machine/system/currentcontrolset/control/class/4d36e965-e325-11ce-bfc1-08002be10318
if you upper filter and lower filter, delete both. restart th computer and that should do it.
