can i format my drive containing vista now ??

hi all...
i have 3 partition in my pc...
C drive contains vista home basic...D drive contains some data and E drive contains new win7 7260
now...i am not using vista anymore..so can i format my c drive directly...
and one more thing..i have lenovo y510 laptop...and it has a one key recovery option...so if i format my c drive....will i be able to use that one key recovery feature in future ???
and apart from 3 partition...i have one more partition which is hidden...in computer management tool...it shows "OEM".
so what do you say ??? is it safe to format my C drive now to get more hdd space ??? but please...i should be able to use "one key recovery"...so reply wisely..please :)

If you haven't messed with the hidden OEM partition, you'll be able to restore C drive to the way it was delivered from the factory.

I should add that if you created new partitions, you may have problems. If you do, you'll have to delete those created partitions before restoring.

please admins....please help me out soon

Did you even read Bum's reply?

The OEM partition is your recovery partition put there by the Manufacturer. This will restore the computer to default settings and programs (OS included) if you want. Don't delete it unless you are sure.

If you no longer use Vista and want it gone, then go ahead and delete it. No problem. Just use delete partition (from computer management) and then extend the Seven (or whatever partition) into that free space.

As I said above: If you keep the OEM recovery partition, you can do WHATEVER you want to the other partitions with no danger. But if you want to restore, you will need to create a new partition to restore to.

ok thanks i hope it works....:) thanks so much :)
but i tell you....i am afraid so much for the first time :P

Then I would recommend you take a full system backup before you start. I know I will. Use a imaging software like Acronis True Image or Norton Ghost.

and one more question...if i format c drive directly...will it be also deleted from the os selection boot menu ???
