Sorry for the possible miscommunication.
In your first post, you stated:
i have Dell N5010 with genuine Windows 7.
But there was no disc provided with it. i want to reinstall my window now and i don't know how.
when i tried it..it asked for disc and all i got is recovery disc that it said is not what it require..
I interpreted the above to mean that you did have
a "recovery disc." While Dell may have provided no
disc when you purchased the computer, most newer computers offer a way to make a recovery DVD
by way of included software. Can you please confirm that you have no discs
for this computer.
If no discs
, can you please see if your computer has software for making a restore DVD:
- Click Start -> All Programs -> Dell.
- Explore all Dell categories looking for Recovery options.
- There should be an option to create one set of Recovery DVDs (possibly a Recovery USB flash drive).
- Please let us know.
