Am windows 7 si mi-a disparut unitatea optica(unitatea cd/dvd-rom) din my computer...
cum as putea sa fac sa reapara pentru a putea sa imi reinstalez sistemul de operare?
am incercat orice si nimic
plus de asta nu boot-eaza cd-ul cu wndows, chiar daca din bios este seatat ca prima optiune de boot ..cd-rom

Solutia 1: daca e desktop pc si nu ai garantie pe unitatea centrala, poti verifica cablurile de conectare. Decuplezi si instalezi la loc.

Solutia2:
Follow these steps to make your DVD or Blu-Ray drive permanently visible:

Click Start, Control Panel and then Tools.
Click Folder options, and then select the View tab.
Clear the Hide empty drives in the Computer folder check box and click OK.

Solutia 3.
1. Click on Start --> Run --> and type in 'regedit' followed by the enter key ( if Vista Start search or windows+R )
2. Expand the "HKEY_LOCAL_MACHINE" key (looks like a folder) by double clicking it (or
3. clicking the "+" next to it.)
4. Expand the "SYSTEM" Key
5. Expand the "CurrentControlSet" Key
6. Expand the "Control" Key
7. Expand the "Class" Key
8. Please look for a key containing the following string of letter and numbers:
{4D36E965-E325-11CE-BFC1-08002BE10318}
9. High light this key by left clicking once on it
10. On the right hand side you are looking for "UpperFilters" and "LowerFilters" under the "Name" column, once you find these please delete them by right clicking on them and choosing "delete"
11. Please exit the registry by clicking on the "X" in the top right hand corner of the screen

Ai cumva un HP?

Desigur, e posibil ca dupa formatare sa iti detecteze unitatea optica. poti formata folosind un dvd extern, sau daca ai un pc nu foarte vechi, folosind un stick usb.
